Blake Protectorate 
This was a short-lived nation that existed during the late 31st Century. It mainly remember as being nation carved out of the once lawless Chaos March at the center of the Inner Sphere beginning in 3068.

However, section which contain the explosion will be destroyed. There are two version of CASE; CASE II, An Advanced version known as which keeps area/critical slot where ammunition that explodes from spreading through the rest of the section. Clan CASE, which weighs less encompasses the entire unit allowing from damage from spreading but not as effective as CASE II.[9]

Massive amounts of resources would be stocked there, including anti-space weaponry, including SDS weapons capable of taking out orbiting WarShips. These would continued to built since the Age of War Era to the later part of the Star League Era, leading to the Star League Civil War. After the fall of the Star League, the fortresses were destroyed during ravages of Succession Wars, though some would remain partially used by various nations who had resources to man them. Many would be lost due to chaos of the Succession Wars, becoming potential Lostech treasures waiting some enterprising individual to discover with it's lost high technology.
Chaos March 
This was region at center of the Inner Sphere that briefly existed from 3057 to 3068. This was lawless space formed in the aftermath of the destruction of the Federated Commonwealth's Sarna March region when it was invaded by the Free Worlds League and the Capellan Confederation. The invasion 3057, netted some worlds lost to the Federated Suns & Lyran Commonwealth as part of their efforts to merge into a superstate. Neither nation secured all worlds surrounding Terra. Thus neither did the Federated Commonwealth FedSun's state nor newly formed Lyran Alliance attempt reclaim these worlds finding themselves independent of any national support. It would become hot bed of instability as Pirates and Mercenary units move in to take opporunity for the need of their services. This would come to end when Word of Blake consolidated it's power, forming the Word of Blake Protectorate, claiming all and more of the worlds of the March.

Clan Invasion 
1) Military Invasion which began in 3049, where the descendants of the self-exiled Star League Defense Forces would return in massive invasion which would result in taking quarter of spiral-ward portion of the Inner Sphere into the divided territories of the Clans invaders. 2) The beginning of a new era for BattleTech, named Clan Invasion Era. This Era spans from 3049 to 3060.
Clan Space 
Also known as the Clan Home Worlds which is located in Deep Periphery. This was region where the Star League Defense Force in Exiled settled. Due to civil unrest among the newly created civilian population, factions formed based on their Inner Sphere nationalities. However, due to wars the Clan society rose the ashes of Pentagon Wars. The region of space divided into two sub regions, Pentagon Worlds and larger Kerensky Star Cluster. The Home Worlds would ulimately be have massive upheaval known as War of Reavings, reducing number of Clan colony worlds as well reduce the Clans there do less than handful.
Clan Tech 
This a technology developed by the Clans of Kerensky during the 28th to 31st Centuries. Technological improvement grow vastly more with the Clans verse the Inner Sphere which lost considerable technology during the Succession Wars Era. Typically Clan Tech is sought out due to the increase damage and weight savings of comparable weapons used by the Inner Sphere and technology developed by the Star League. Only the Clans were able to produce this technology. It would not be further available to Inner Sphere powers by the 32nd Century.
Combat Information Center (CIC) 
The Combat Information Center or CIC is a central control room designed coordinating strategic & tactical situation for base to spacecraft such as DropShip or WarShip. Version of the CIC can be found Mobile HQ Vehicles, which act as wheeled/tracked CIC for ground forces. CIC is general found on naval related organizations. CIC can at as control room or bridge for such naval/Aerospace vehicles.
Combat Vehicle 
This is a term for any combat oriented frontline type of vehicle. In BattleTech, Combat Vehicles (sometimes referred to as Armor or Armour (by Europeans). These vehicle are not just known as Tanks and not limited to ground base vehicles, VTOLs (Helicopters) can also be classified as a Ground Vehicle. Combat Vehicles are categorize by how they move/locomotion and by weight. There are four Canon weight classes;
Light Combat Vehicle : This is a vehicle between 1 to 35 tons.
Medium Combat Vehicle : This is vehicle between 36 tons to maximum of 55 tons.
Heavy Combat Vehicles : This is a vehicle between 56 to 75 tons.
Assault Combat Vehicles : These are vehicles between 76 tons to 100 ton, were the largest size a ground non-naval vehicle could be. These vehicle were known to be very slow.
Super-Heavy Vehicles : Extremely rare, ranging from 101 tons to 200 tons, (Naval vehicles can be maximum weight of 555 tons). The Super-Heavies were not widely available to all faction until the Jihad Era, yet still rare.
Types of Locomotion is other category used to classify a Combat Vehicle. They are;
Hovercraft
Wheeled
Tracked
VTOL (Vertical Take off & Landing)
WiGE (Wing In Ground Effect)
Naval (These include submarines as well hydrofoils & displacement hull (regular ships).[11]
Combined Arms (Formation) 
This is the military formation in which integrated and mix vehicles/BattleMechs/Aerospace Fighters/Battle Armor in more interweaved unit. Where most typical commands keep different types of combat units (vehicles/mechs/VTOLs etc) separate, Combined Arms formations do not. Initially by SLDF era, these types were found in Regimental Combat Teams, using separate Regiment / Company / Battalion size forces of mixed types. However, by the 31st Century this would change. Pioneered by secret hidden army of ComStar, the ComGuard. Which on their own unique formations of Level I (1), which 6 units of any type can mix. (example; 2 tanks, 4 mechs). By the Jihad and it's aftermath, military resources would be scarist. Setting stage of Combined Arms being the norm. A typical combined arms mercenary company of troops consist lance (4) Mechs, by 2 Lances of (4) Tanks/Combat Units, 2 lances of Battle Armor or Infantry Platoons. Large formations may feature Combined Arms Battlalions with company of twelve Mechs, with 1 Lance of Mechs split between each Companies. This breakdown of less Mech stemed from military reductions via treaty by instituted by the Republic of the Sphere. By 3132, when Gray Monday triggered massive conflicts between nations and it's own worlds having splinter groups. This arrangement of Combined Arms combat units would be the normal mixing with civilian vehicles & IndustrialMechs being armed for combat. Some cases Mechs, BattleArmor, Ground Vehicles tied into the same Lance (of 4 units).
Company (Formation) 
This a military formation of troops, 2nd largest non-infantry formation. Typically associated with vehicles/mechs and mechanized formations. A company consists of four Lances of troops. Troops in this formation usually consist of 12 BattleMechs, Combat Vehicles, Aircraft (sometimes). Clans do not use this organization, they employ what is referred to a Binary which is 10 such units, however typically are more powerful due to typically difference firepower and technology. Companies are typically commanded by officer of the of a Captain. There other version of the company, such as reinforced (extra lance), augmented (organized mix of vehicles/troops) and combined arms company which is mix Battle Armor, 'Mechs, and Combat Vehicle blended together in lances.[12]
Command Circuit 
This is method of travel arrange for DropShips to be relay to pre-arranged JumpShips awaiting to take the arriving vessel for next leg of travel. Thus a DropShip, flies to the waiting DropShip to be immediately taken to it's destination or another waiting JumpShip. This is used under extreme circumstances by governments and extremely wealthy individuals. Due to coordination need to undertake this effort. Typically DropShip going to another part of the Inner Sphere requires months of changing JumpShips or waiting week roughly for it's original JumpShips to charge for the next jump.
Concord of Kapteyn 
This was a treaty sign in 3022 by Capellan Confederation, Draconis Combine, and Free Worlds League. Brokered by ComStar, this was intended as an alliance to counter the pending merged of the Federation Suns and Lyran Commonwealth into a super state later known as the Federated Commonwealth. The treaty ultimately was interstellar failure of diplomacy due to lack trust of all three Succession Houses when the Armed forces of both the Federated Suns & Lyran Commonwealth conquered large number of worlds between the two nations allowing them to have unified and secure border.[13]
Combat Vehicle 
Combat Vehicles are more traditional ground vehicles used for combat in the Battletech universe. They evolved from normal combat vehicles used since the 20th Century on Earth. Like BattleMechs, they can equipped with array weapons and armor. They were sidelined as leading combat vehicle when BattleMechs were invented, however they continue to support and be used in battle. These are family vehicles broken down to sub types based on their propulsion system. A Combat Vehicle must be under certain weight class for Combat types.
ComStar (Faction) 
This is was organization that was originally created by the Star League Counsel after the Star League Civil War as caretakers of the massive interstellar communication arrays known as HyperPulse Generators. The HPG Network allows communications between the stars. As centuries past, in effort to sustain itself from onslaught of the violent Succession Wars, ComStar turned to a religious dogma in order to prevent secrets of its technology to leak out and provide integrity to the organization with hidden goal restoring the Star League under it's direct control. Hidden until the 31st Century, was the ComGuard. The Armed forces of the ComStar, virtual army not unlike the Star League's SLDF of old, which would play prominent role in stopping the the Clans from taking the Inner Sphere. It would be 3050s ComStar would sudden be sundered into two factions, ComStar being one without the religious trappings and one imbedded it named the Word of Blake (WoB) which would set for final showdown by 3070s where a very weaken ComStar would fight with rest of the Inner Sphere against the WoB after trigging conflicts of the Jihad Era. The organization itself began in 2785 and ended 3150 after its bankruptcy when a Hyperpulse Generator Network was sabotaged causing communication blackout through out the Inner Sphere, better known as Gray Monday. ComStar's slow demised over few decades would ushering new age of conflict known as the the Dark Age.
Com Guard 
This is the armed forces of ComStar, the operators of the HyperPulse Network Generator (HPG) Network. The Guard formed in secret during the Succession Wars as secret army. First formally appeared as security guard force for the Generator Stations, where communication signals are sent across space. However, using mercenaries as trainers and others in secrecy, by 31st Century, the order had grown impatient waiting formerly standing up army. By the Clan Invasion, the ComGuard Army had made full appearance in 3051 where it fought the Clan in Trial of Possession for Terra. In course battles, beat back most of individual Clan armies in massive global battle on Tukayyid‎. The army fragmented when ComStar shredded it's religious trappings, giving birth of opposing force known as Word of Blake Militia. ComGuard was size of Armies which no Inner Sphere power could field at the time of the Invasion. By 3070s the Jihad had shattered the Guards, and it's remaining fight forces would be used to liberate Terra with others as part of a coalition force. The ComGuard would be disarmed and absorbed into the Republic of the Sphere's new army. Splinter group in 3140s would use a single Division of forces in ComGuard name, but it would be short lived and last Guards would be destroyed.

Com Guard Formations: Com Guard base their formations on Levels. An individual unit are referred to as Level I. These Level Is usually operate in formations basis of groups of six combat units usually mix different types units, known as Level II. These were could be mistaken as demi-companies. Each Level II allowed for any arrangement of combat force from all 'Mech formation or mix infantry platoons and combat vehicles or all fighter craft, or mixture of Mechs and Combat vehicles and so forth. Six Level II form Level III, which is a formation of 36 Level I or individual combat units which also known as a Battalion. Six Level IIIs is referred to as a Level IV or a Division which consist of 216 Level I/Combat Units. The largest formation in Com Guard are Army size force or Level V, which consists of six Level IVs. This 800-1000 Level Is force is seldom operates together. Typical Com Guard deploys it's Level IIIs together to allow for flexiblity and ease of transporting the formation.[14]
Circinus Federation 
In canon is a Periphery nation which is situated on "western" part of the Inner Sphere's borders of the Lyran Commonwealth and Free Worlds League. The nation culturally seen as a pirate nation and was taken over by the Word of Blake in 3060s. It was destroyed by the end of the Jihad by mainly fragmented forces of the former Free Worlds League in 3081.
Cluster (Clan) 
This is third largest combat formation used by the Clans. Clusters consists of usually 3-5 Tinaries or 3-5 Binaries, Supernovas, and/or Supernova Trinaries. This size formation usually commanded by a Star Colonel.
Cyborg 
This an augmentation (also known as bionics) of a person with mechanical parts. Uncommon in the BattleTech universe, usually forego due to taboos or bias towards persons with replacement for lost limbs due to varying degrees of accidents or injury inflicted in combat. Typically, this bias comes from the Free Worlds League worlds, where past leaderships whom had been enhanced faster injury turned bad and gave bad impression. The Jihad war period, the Word of Blake special troops, namely the Manei Domini were terror to both soldiers & civilians alike whom though themselves above mere weak "flesh" people cemented this negativity / bias towards individuals augmentation with bionics. However, not all share this personal. Battletech prior to the Jihad had 5 levels of bionic replacements from simple hook to fully flesh-like covered limbs replacements. The 3060s saw rise of more advanced (or Lostech) mechanical enhancement where Intelligence & Special ops troops (primarily Word of Blake) purposely replaced injured troops damage/crippled limbs or other organs with mechanical ones with superior abilities, strength, and even beauty improvements for their intended missions/job profiles. See Manei Domini for further information.

D[]

Dark Caste 
The Dark Caste is an unofficial designation for people who live outside Clan society. This caste are also known as "Bandits Caste". They are considered to be outcasts and criminals of the Clan society. While not definition of these individual people. They sometimes raid Clan settlements for supplies. While groups Dark Caste can vary, they do tend to live primitively, with little technology. However, some of the Dark Caste has technology (stolen or salvage) and can travel between worlds, which is rare. Clan politics uses the Dark Caste to as means for Warriors to hunt like animals when not otherwise engaged with other clans in official trials. Warriors seldom use their tradition of Zellbrigen (fighting with honor rules) when hunting bandits of the Dark Caste.
Davion 
1) The main ruling family name of the Federated Suns, these are given the title of either First Princes or Princess. The family known to be the primary movers in the politics of the Inner Sphere. There are splinter off of the family, including Steiner-Davion, whom went on to directly & indirectly influence nearly every major nation in the Inner Sphere. It should be noted that there are "cadet" off shoots of the family, which uses a hybrid name examples; Hasek-Davion, Green-Davion, etc. 2) (Slang) A reference who is a citizen of Federated Suns, who is under the rule of House Davion family.
"Death From Above" (Tactic) 
This is a tactic used by MechWarriors with 'Mech equipped with Jump Jets. A desperate gamble, seen as unhonorable by some among the Clans. This is when a Mech uses their Jump Jets to go airborne above another target and then cut their jets to allow the weight of their machine crush the target below them. However, this is dangerous maneuver which requires good piloting skills as well luck that target's pilot is not better they are. Resulting them moving out of the way causing only damage to the dropping Mech.
Demi-Company (Formation) 
This is a "half" Company usually consisting of six units, such as BattleMechs or Combat Vehicles. In some factions, Demi-Companies are also known as Reinforced Lance, which is a combined arms formation usually consisting of two types of combat units; example BattleMech lance of 4, augimented with pair of Combat Vehicles, pair Battle Armor squads. The ComGuard uses Demi-Companies in their basic formation known as Level I, where all six units of the formation are interchangeable with all types combat units found in BattleTech.
Dezgra 
This is a Clan term/slang for Disgrace. A person with no honor. Which Clans hold honor above all else.[15]
Dispossessed 
This is status of disgrace for a MechWarrior. Where the warrior has lost his 'Mech in combat or other reason. This is considered a dishonor and disgrace among MechWarriors. While government troops in less risky times can re-assigned readily available 'Mech, however during the Succession Wars and even Dark Age Era this would be point no return. Where during earlier wars, the pilot would need capture a 'Mech for themselves from enemy forces or die as infantryman which was highly likely thing to occur.
Division (Formation) 
A large military formation consisting of three Brigades troops (9 Regiments). These very large military formations were almost exclusively used by SLDF, the armed forces of the original Star League. Due to the sheer size and logistics required to these formations into a combat area, Inner Sphere powers do not have means to move or even man such staggering size force in modern BattleTech times. A alternate version of the Division was used by ComStar & Word of Blake's armed forces in the 31st Century. These Divisions consisted of (formally named Level IV units), 216 combat units. However a unit could be an type of troops/vehicles/mechs/aerospace vehicles, thus a combined arms formation. While SLDF was known not mix their forces together beyond regiment size.[16]
DropShip Collar 
A Docking Collar is a common mechanism found on JumpShips and WarShips. This device allows smaller DropShips to mate with large interstellar vehicle to be transported to another solar system and be able to detach once it reaches it's destination. Docking Collars can not handle strain of interplanetary engines, Military JumpShips / WarShips must release their DropShips from it's collars or risk it being torn away from the vehicle once it's big engines start moving.[17]
Draconis Combine 
This is the of one the major interstellar nations of the Inner Sphere located Northeast of Terra/Earth. Draconis Combine is a communist style nation, which whom culture is heavily influenced by pre-World War II Japan. They are generally ruled by House Kurita (family) and their supreme leader known as the Coordinator. The soldiers of the nation follow strong Bushido/honor not unlike Japanese Samurai culture once followed. The nation symbol is the Dragon, which it's leader, the Coordinator, is referred to as the Dragon.
Draconis Combine Mustered Soldiery (DCMS) 
This the name for the overall armed forces of the Draconis Combine. Commonalty known as the DCMS, they are charge up holding the honor and defense of the dragon. They are known to in some time periods to prefer to duel their opponents for personal honor. The DCMS like all armed forces is broken up by it's divisions; Draconis Combine Admiralty [DCA] (all things Aerospace; rare Warships, DropShips, and Aerospace Fighters are among other units that this branch handles.) Regular and Regional Forces. Typically, they are named for the Region they are assigned to defend and raised from.
DropShip 
DropShips are the most common interplanetary spacecraft with the ability to land on surface of a planet or other type of object. They largely employed as form of transports for civilian or military equipment. They range from 500 tons to maximum of 100,000 tons. These ships come in two forms, Sphereiod (circular/ball shaped) or Aerodyne (like a plane, with wings). DropShips can externally dock with interstellar spacecraft known as JumpShips, to allow them to travel across the Inner Sphere. Prior to the modern JumpShips, these primitive DropShips (known as DropShuttles) were restricted to the maximum weight of 5,000 tons due to limitations of Primitive JumpShips. Dropships are organized by roles; "Carrier" for any type vehicle/mech/aerospace fighter, Passenger/Civilian/Cargo Transport, Assault (combat ship), Tug (moves larger vessels, or space bound objects), and the Pocket WarShip (Which has capital and subcapital weapons dedicated to anti-Warship combat).
Drop Port 
This is a form of paved landing area that used principally to handle DropShips, and other instellar commerce. While extend of facilities can vary depending on the development of the planet, these space ports generally will have super damage resistant Ferrocrete pavement, with controller tower. Vertically landing Spheriod shaped Dropships (Oval / Circular Shaped) have special landing pads, while a landing strip is made for aerodyne Dropships and other winged vehicles. These ports may as few as one or two per world, which also can act as inter continental travel points for DropShips and smaller vehicles to travel in sub orbital travel around a planet. These Drop Ports are usually house warehouse for commercial traffic and finds itself target of invasion or raids conducted hostile forces.

Exarch (Title) 
This the title given to leader of the Republic of the Sphere, whom a council of Paladins of the Sphere vote among their own peers.
Enclave 
Term for self-contain settlement established by a Clan. A Colony with it's own industrial & defense functions, with housing and self-defense assets. Like most Enclaves, these city-states relay on other such Enclaves or trade to sustain itself. Clans have been known to keep it's citizenry (castes) contained in these cities. Many which can starve due to lack farm lands.
Element (Combat Formation) 
Name representing smallest component of a military formation. Sometimes referred to as a Unit. Elements can represent; Platoon Soldiers, Individual Battle Armor, one Combat Vehicle, a BattleMech, an AeroSpace Fighter, or singular combat oriented component found in fighting forces.

1) This is a generically engineered human intended for infantry world created by the Clans. They are extra large humans, sometimes seven feet tall, with massive muscles and highly intelligent. They typically are associated with use of Battle Armor, a type enhanced powered combat suit. 2) Type of Medium sized Clan Battle Armor, which is the standard model Battle Armor for Clans to deploy.
Electronic Warfare Suite (ECM) 
This device found range of vehicles, Mechs, Aerospace vehicles, and Battle Armor.[18] In terms of BattleTech game, Electronic warfare is intended to jam sophsicated equipment from establishing lock-on or strong-signal to locate user of the ECM. Typically, referred to ECM Suite, or it's brand name Guardian ECM Suite on Mechs, planes and combat vehicles build by the Inner Sphere powers. ECM can undo-jamming caused by ECM (called ECCM ) as well create a "Ghost" element causing radar and other sensors to see double image of the target. More advance ECM exists as well the "standard" Guardian ECM or the ECM Suite typically found on Clan built units.[19]
Endo Steel 
This is a Chassis component communally used in BattleMechs. This a light weight skeleton structure created by Star League Technology. Usually in canon, this is only created in space/orbital factories verses on the planet.
Era 
Era is measurement of time in the BattleTech universe, where measured amount of years/centuries is labeled due to a significant historical event that accrued during this time period. Time is also broken up by "Sub-Eras" which has major event that warrants notice within the Era. Currently the canon Battletech Universe has 7 known eras.
  • Star League Era - Age where the rule of the Star League, it's dominance of all humanity from it's formation and it's downfall. This era ushered in new technology, some in which has gone unseen before and since it's demise. Like hidden treasures, some this technology is referred to as Lostech.
    • SubEra - Age of War - Early Time period the where all Inner Sphere powers fought for dominance and formation of the major nation emerged as the newly formed Terra Hegemony , which guide it's former colonies to stop their destructive Total Warfare and eventually come under their leadership as head of the Star League superstate.

    • SubEra - Golden Century - This is a time period after the establishment of the Clans and reclaiming the Worlds of the Pentagon Cluster when technology and economic improvements rose to heights not seen by the Star League, seen by the people of the Clans of pinnacle their culture's development. Despite end of individual freedoms and purges of various Clans such as Wolverine, Mongoose, and Widowmaker being removed for various reasons.
  • Clan Invasion Era - Time period that the Clans, descendants of the Star League self-exiled armed forces returns in form of Warrior ruled Clans to conqueror the Inner Sphere and restore the Star League.
  • Civil War Era - All major Inner Sphere powers turn on each other.
  • Jihad Era - Second Star League, which was formed to defeat the Clans and maintain peace in the Inner Sphere is dissolved due to the events of the Civil War Era. The Word of Blake, their main purpose to reform the Star League goes on blitzkrieg and strikes capitals and major industries of the Inner Sphere in attempt restore the lost League and carve new nation at center of the Inner Sphere for themselves.
  • Dark Age Era - This time period where the newly form Republic of the Sphere is formed and governors in the name of peace until 3132. This is when the Inner Stellar communications network is destroyed, causing the Inner Sphere to turn from peace to war . Causing old rivalries and ambitions pent up from 70 years of peace to turn malevolent.
    • SubEra - Republic Era - Formation of the Republic of the Sphere and wars it fought in early days to establish itself and the moves try to stabilize its nation and promote peace across the Inner Sphere.
  • IlClan Era - Manifest destiny of the Clans is fulfilled, where one Clan takes Terra forming the IlClan, the replacement for the fallen Star League.
Escorpion Imperio (Faction) 
This was a Clan / Periphery nation, in Periphery. Fusion and conquest of the two Deep Periphery nations by Clan Goliath Scorpion. Ejected from Clan Space, the Clan travel it's entire Touman to Nueva Castile and the Umayyad Caliphate. These low-tech factions had been locked in war for centuries. Once conquerored in 3080, the Imperio would quietly rebuild itself as it prepared to conqueror the neighboring Hanseatic League in 3140. This conquest result in nation changing itself into Scorpion Empire. Little is known beyond the conquest since itself has cut ties with the Inner Sphere completely, as it fends off probes done by the Clans in old Homeworlds of the Kerensky Cluster.
Exodus (Events) 
In Canon BattleTech history there been five events named "Exodus". The original one is not often referred to as the "Exodus". 1) Exodus (2102) & (2313) - These events were named alternately First & Second Exoduses. This extremely early mass migration from Terra in late 23rd Century which lead to colonies that would later become future Succession States and Periphery states. This was when the K-F Drive was initially invented. Second Exodus was result of the rise and fall of Terran Alliance. As people left Terra for new worlds. This lasted until Alliance's political upheaval which lead to isolationist party of the government to issue the Demarcation Declaration which cut off all contact with colonies beyond 30 light year radius. 2) Operation Exodus, which is also referred to as the Exodus. This is when the SLDF abandoned the Inner Sphere, lead by Commanding General Kerensky in to the Deep Periphery. After year travel and hardship they would colony small cluster of habitable worlds known as Pentagon Worlds establishing the Star League in Exile. 3) Known as the Second Exodus, this was lead by Nicolas Kerensky, son of the Commanding General, whom lead loyal SLDF forces from the chaos ensuing the Pentagon Worlds to the expansive colony region where he would found the Clans and train his people for conquest of the Pentagon Worlds.
Exodus Road 
This is the course the SLDF Fleet (also known as the Exodus Fleet) had used through the Deep Periphery to reach region of space they would settled. The Exodus Road is highly protected and guarded from non-clan. Originally, not even the crews of the JumpShips used to move along the Road have complete course that makes it up, or it's is locked in the NavComputers. Exodus Road is also a Clan cultural & historical significant event, since it part their eventual founding.
Exoskeleton 
This is a device that used to enhance individual person's strength. Typically in the BattleTech universe, these mechanical suits use Myomer muscles and metal skeletons powered by batteries. Mainly intended use for civilian handling heavy objects such as small cargo and moving heavy objects. Police use these devices as "poor man's" Power Suit, for conditions where they need added strength and ability carry heavier loads such as worn armor and infantry size weapons.[20]

Federated Commonwealth (FedCom) 
Was a interstellar superstate, a nation that existed during the 31st Century in 3028 till 3067. Second largest interstellar state of the Inner Sphere since the Star League. The nation consisted of two existing Succession Houses, House Steiner & House Davion. Briefly merged with the heir of Hanse Davion and Melissa Steiner (now Steiner-Davion) being head of the new nation. Known also as the FedCom, the Fourth Succession War declared in 3028 at marriage of Hanse and Melissa as part of plan to allow both states to merge with borders secure and sunder any nation that stood in it's way. By 3057, enemies of the FedCom mounted a invasion that would destroy region linking House Steiner and Davion. With the House Steiner half of FedCom declaring it's independence from FedSun half, calling itself the Lyran Alliance, lead by Katherine Steiner-Davion. Archon Katherine (Styling herself after grandmother as Katrina) would take over the House Davion half with her bother, the Archon-Prince Victor Steiner-Davion, leading the reborn 2nd Star League against the Clans. On his return within few years of abuse to his people on both sides, Katrina, tyranny growing, Victor would declare war. Victor begun the gathering forces under collective name of Federated Suns, stating FedCom was dead. By 3067, the FedCom Civil War[21] was over, with both nation states with new leaders and FedCom now formally dissolved. FedSuns portion of the FedCom would revert back to it's name, Federated Suns once more.[22]
Ferro Fibrous 
Ferro Fibrous (Abbreviated as FF Armor) is a type combat armor used on various type of ground and aerospace vehicles. While not stronger than Standard Armor, it is lighter. This allows for additional heavier equipment to placed in a unit which has it. Trade off is the armor takes up room inside (critical spots) which cuts down on number things that may be mounted on the vehicle. There are other types of FF Armor, such as Light Ferro Fibrous armor and Heavy Ferro Fibrous armor.[23]
Ferrocrete 
Ferrocrete is a high grade construction & pavement substance used commonly by modern Inner Sphere & Clan societies. It is a super tough material in construction of buildings as well as pavement. Where older concrete would crumble under the weight of repeatively heavy vehicles, such as military and civilian Mechs which routinely 100 tons in some cases.[24]
Federated Suns 
A interstellar nation founded in the (southeast) from the center (Terra) of the Inner Sphere. Open culture, capitalist nation, which has French/British influences in their culture. They are referred to as being "Good Guys" of the BattleTech setting, but since changed. They are known for their most democratic of Inner Sphere nations. They are lead by leader titled, "First Prince". The nation broken up in large border realms known as Marches ruled by Dukes/Duchesses, while smaller regions are referred to Combat Theaters and PDZ. These smaller zones help better organize worlds from invasion and it's defenses.
Fidelis 
This is a people whom live in secret in the Republic of the Sphere since founding til it's fall in 3150. Knowledge of the Fidelis is unknown to the Inner Sphere in general. The people of the Fidelis are descendants of the last of the Clan Smoke Jaguar. In order to survive, they removed all signs of their people's former identity. During their time since 3061, they lived in secret roving world to world, becoming highly skilled at any job they take. Treating its people equally. They would during the Jihad in 3070s become into the service of Devlin Stone's Coalition Army eventually in service of the Republic of the Sphere as a secret special ops group only known by Republic's top leader. They will undertake services for the Republic as debt paid for allowing them to settle in secret on the world of New Earth. They would remain in service until their debt to the Republic was paid, allowing them the freedom to choose their destiny. Their armed forces among the Fidelis were the most skilled, even comparison to the Clans by the end of the Dark Age Era. Their people's leader known as the Custos (Latin for Custodian) guides his people until the day they ma reveal to the Inner Sphere who they really are.
First Lord 
The title of the individual whom rules the Star League, the intergalactic empire that once ruled the entirety of the Inner Sphere & surrounding Periphery.
First Prince 
The title is designated for anyone whom rules the Federated Suns and short-lived Federated Commonwealth (as Archon Prince). The use "First" harkens back when each of the
Flamer (Weapon) 
This is a high-powered form of flame thrower which is usually powered by Fusion Engine of a unit, while non-fusion power vehicles / troops use chemical ammo. This ground weapon typically does not much damage to large units such as BattleMechs however, they can cause target to heat up cause them to be sluggish or non-functional. Combat Vehicles or other units without Heat Sinks to obsorb flame heat can cause target to be burn of and be rendered destroyer. Classically, the weapon has been used to burn woodlands or other flamable objects for purposes create cover. However, the weapon is used as well anti-personal weapon.
Fourth Succession War 
See Succession Wars
Free Guilds 
This is a loose group of merchants which reside lowest reaches of Clans' Society. Wild considered to be a tolerated version of the Dark Caste, which acts like formal version of the Merchant Caste. They are also necessary group within Clan Society that supports it. They would eventually be reaved (reduced) in Wars of Reaving in early 3090s by remaining Homeworld Clans.
Free Worlds League 
A interstellar nation founded in the (southwest) of the Inner Sphere. Open culture, capitalist nation, which has Greek/Indian influences in their culture. Originally a democratic nation, ruled by a Parliament, the nation politics' is highly fragmented, in cases of emergencies, the Captain-General is given powers to rule the country. However centuries past, the position became semi-permanent.
Free World's League Armed force is Free Worlds League Military (FWLM).
Freeborn (Term) 
This is a natural born human, which this term is used with the Clan society. This sometimes used as insult used by Trueborn (artificially created humans) against one another, due to Clan society viewing Trueborns are superior genetic stock in skills, abilities, strength and intelligence. However, Freeborns / normal human can be just as equal to Trueborns, surprising them.
Fuel Cell (Engine) 
This is a uncommon powersource used typically used for low-end commercial & combat oriented vehicles, and in rare case Industrial 'Mechs. Unlike conventional internal powered engines (ICE), this is a type of hybrid of fuel & electrical engine components which essentially an conventional fuel generator. Like ICE engines, they do need power amplifier to power energy devices. Power Cell saves weight, tempature management, and costs. However, its is not as poweful as a Fusion Engine.[25]
Fusion Engine 
This is the principle power source used by all combat units (Mechs, Aerospace Fighters, Combat Vehicles (Tanks), WarShips,) in the game that has room to fit it. A form of Cold Nuclear Fusion, this is a type of "Safe"/Low Radiation power source. They vary in size with engine/power ratings. There are four variations of this type power source aside from the standard fusion engine; Light Fusion Engine (Lighter than standard engine, allows more speed and weight savings to add equipment.), Extra Light Fusion Engine (Known as the XL Engine, it is similar to the newer Light Fusion Engine, but its weight savings takes extra room. Notorious known for taking up room in the side torso of 'Mechs, making them more vulnerable being damaged/crippled.), Compact Fusion Engine (Also known as Compact Fusion, it is heavier than standard engine, less vulnerable to being damage.) The Clan versions of the XL Fusion is not easily crippled by engine damage.

H[]

Hanseatic League 
This is a Deep Periphery nation located Coreward, Anti-Spin. ("North" of the Inner Sphere), it is a mercantile nation founded principally by former Lyran Commonwealth citizens escaping the devastating Succession Wars. The nation focus on trade, was known player in having it's neighboring deep periphery nations attack each others. The nation most advanced of the three nations ( Umayyad Caliphate and Nueva Castile), employing barely Succession War level technology if not scarcely BattleMechs at all like it's neighbors.
HarJel 
This is special gel like substance which can repair any physical component of machine which may have been damaged when it hardens. Typically this used in Clan Battle Armor to temporary repair the suit and it's occupant. Also, it is with spacecraft fill in gaps when hull is breached. Casually, BattleMechs are repaired, but it not common.[29]

Heat Sink 
This is a device that regulates heat in a various fusion power machines found in the BattleTech universe. Often associated with BattleMechs or devices that creates high rate heat from using energy base applications. This is similar to a automobile's radiator, they govern fluids through them which can be toxic. Other version of the Heat Sink were created, most common these is the Double Heat Sink, (double heat obsoption), Compact Heat Sink (Smaller, heavier) and Radical Heat Sink (Able to remove all heat for so many turns before possible failure).
Heat Sink, Double 
Variant of the standard Heat Sink, this version doubles efficiency of cooling effects for a machine's heat issues. Prototype and earlier version of this device are sometimes known as freezers.
Hegira (Term) 
This is the Clans word for request for honorable retreat from the battlefield. An opponent would gain all that is on the battlefield itself as well the objective of the Trial that was fought if Zellbrigen was called.

Hesperus II (World) 
This is a key military manufacturing world lying in the Lyran space. Originally established by the Terran Hegemony as part their shared worlds, this planet became key BattleMech manufacturing plant built into the planet's famed Mountain rages that dominates much of it's surface. The factory fortress became target of faction over the course of the centuries only having fallen to the Word of Blake during the Jihad Era briefly. This became the House Steiner's most important of worlds as part of their backbone of the their defense forces means to replenish their losses.
Holotank 
It is a device that projects 3D image on computer projection table. Typically these devices are use strategic planning board.
Holy Shroud, Operation 
This was Succession Wars Era undercover operation conducted by the Comstar. This operate was meant to accelerate the technological decline of the Inner Sphere's nations by killing the majority of the leading scientist. This was done in order usher the time where they would no longer be able to build technologies which only Comstar would hold. Once the nation were to be unable wage war, not even travel between worlds...Comstar had planned execute plane of mass take over to save humanity, no one would be able to stop them.
Hyperpulse Generator 
Better known as the HPG. This is a specialized technology which allow gravity pulses to be sent through hyperspace to allow communication between the stars. The technology is related to JumpShip's K-F Drive. A HPG is capable of sending message not unlike the Telegraph, but with more advanced ones using visual recordings, however very expensive. Most common HPG is planet base, named a HPG Station. The HPG Station consists of massive control dish which it must align itself planet or orbital body which has another Hyperpulse Generator Station. There are different grades of these stations which handles message traffic. Basic communication is text, while higher grade is video messaging, while in very rare occasions, highest grade of stations can be made create a Real Time communication, but disrupts message traffic tremendously due main power, and individual stations needed to make the connection. Clans and the Star League developed smaller Mobile HPG
Hyperpulse Generator Network 
This a massive network of HPG Stations build and used by Star League and more notably ComStar throught the Inner Sphere. The Clans also maintained it's own network of HPGs, some more advanced and not connected to older Inner Sphere Network.

I[]

Improved Advanced Tactical Missile (iATM) 
Variant of the long range ATM system, it was developed by renegade scientists known as The Society in 3070 during the Wars of Reaving. Called the Improved Advanced Tactical Missile (or iATM), they have same type missile tubes/launchers (iATM-3, iATM-6, iATM-9, & iATM-12) but use Streak SRM (fire & forget) technology and unlike SRMs can used for indirect fire. The iATM uses same warheads as the regular ATM, but included two additional alternate ammo types; Improved Magnetic Pulse Ammunition and Improved Inferno Ammunition.[30]
ilClan 
This is designation for Clans of Kerensky of the one Clan that shall lead others. To designated the IlClan, this clan would need to conquer Terra, which would usher the reestablishing the Star League by conquest of the Inner Sphere.
ilChi 
This is a Clan title for a State Messenger who goes between Clans as representative. This is not unlike function of an ambassador. This is a unique position created by Clan Blood Spirit, as part their founder's efforts to encourage good relations between war like Clans. However, this position was abolished as possible Clan-wide due to increasing aggressiveness nature of Clans had evolved to being "UnClan-Like". Despite this, Blood Spirits kept for Clans they had friendly relationships with. It's unknown if the position was maintain beyond Blood Spirit's annihilation in 3084[31][32]
IndustrialMech 
This a civilian type of 'Mech, intended generally for commercial uses or non-combat labor. They are sometimes referred to as "WorkMechs". Their roles include; Salvage, Cargo handling, Agriculture, Ammunition handing, and Security. Typically these machines are powered by Internal Combustion Engines (ICE) and usually are fitted with industrial grade armor which isn't as strong as standard armor found on BattleMechs. However, they can be armed in desperate situations. Mechs modified in this fashion are designated with MOD (if their formerly civilian models), signifying it's a armed IndustrialMech. However, planetary militias do field what term as purpose built MilitiaMechs, which are low-tech combat mechs. These "combat" versions of the IndustrialMech can be fitted with heavy industrial armor and added military grade equipment which are more survivable than IndustrialMechs retrofitted with weapons. SecurityMechs are have similar abilities, but not as significant as a MilitiaMech. However, if either design faces modern BattleMech, they would not be able last in combat for but just short while.
Inferno 
The Inferno missile is a warhead used with SRM launchers. They contain a flammable plasma warhead that explodes into head and damage. While not damaging warhead, heat from the weapon can cause unit being stuck to suffer from possible shutdown or utter destruction due to intolerance to flammable warhead. Only SRM Launchers may fire Infernos. Similar non-missile launchers include Flamers type weapons.
Inner Sphere 
This is given name of the BattleTech universe's setting in side the Milkyway Galaxy. This region does not consisting of entire galaxy. However, it does include a massive part of it. Anything beyond heart interstellar civilization is considered to be Periphery (on the border if the Sphere) and the Deep Periphery refers to anything beyond borders of the Inner Sphere. After certain point in BattleTech's universe, most deep space exploration & mass colonization on whole ceased. Center of the Inner Sphere is Terra (Earth).
Intel 
Abbreviation for Intelligence, in military organizations it is information on opponent actions.
Interstellar Expeditions 
Also known as IE, This is a privately funded organization dedicated to exploration, usually for profit. Formed during the late 30th Century originally by hobbyists. However, by the 31st Century it became organization was used probe into the Deep Periphery as well as mysteries of the Inner Sphere's past that maybe profitable.[33]
Iron Womb 
This is the name for the device that used to birth the Clan's genetically engineered Humans as possible Warrior candidates. The devices maintained by Clan Scientists using the DNA of previous genetically Blood-Named Warriors (referred to per sex, Gene Mother, Gene Father) who earned right to contribute their genes to creating new generation of warriors. Different or multiple individuals can be used to contribute to the creation of a child. Including of the same sex.
Isorla 
This is the Clan term for spoils of war or battle. This can be set as a prize for a Trial or winning a battle. This can include individual warriors who showed honor & skill opposing them to entire planets. Depending on the circumstance.

J[]

Jihad 
This was a time period of war (3067 to 3081) in the Inner Sphere where the Word of Blake. Tech-influence religion faction angered with collapse of the Second Star League, would launch strikes at all the major capitals of the Inner Sphere and engineered sub-factions to fight one another. In meanwhile, they would make their own land grab forming a new nation in center of the Inner Sphere, with Terra as it's capital. Though this name of era, Word of Blake waged war against everyone, thus sometimes over all time period is though of a War onto itself. Sometimes being referred to as the "Jihad" or "Blake War". However, this is inaccurate due to the many different small conflicts & short-wars were accruing during the Jihad until the end.
Jump Jets 
Jump Jets are form of vehicular type equipment typically found on 'Mechs or Battle Armor. They are form temporary jet booster, that helps a unit to be propelled into the air for short period and lands certain distance depending on how many Jump Jets are fitted on the unit. This method of movement is consider to be a "Jump" as a person would do. They are typically powered by a unit's Fusion Engine, giving significant mount power to do this Jump. Jump Jets cannot be used while in water if the jump jet nozzles in water itself. Jump Jets can be used in space, though additional "fuel" can be fitted for more sustain flight. While rare, Combat Vehicles can be fitted can be fitted special jump jets. Game mechanics have made this rare, to give Mechs and Battle Armor more uniqueness in the game. There are three types of Jump Jets; Standard Jump Jets (which have no distinction from Battle Armor, BattleMech/OmniMech), Improved JumpJets, which double distance (and heat) a unit may move, Vehicle Jump Jets (rare form, only Combat Vehicles/OmniVehicles may use), and Jump Jets found on LAMs, which are form of Super Jump Jets only these transforming BattleMech may fitted with.
Jump Point 
A jump point is area in space which a JumpShip safely exit and enter hyperspace. These regions of space labeled are usually area with no gravitational influences. Such factors cause MisJump and resulting harm to the ship conducting the jump. The Zenith and the Nadir of a star's gravity well usual designated Standard Jump Point used by interstellar commerce. However, other such places such as "Pirate Jump Points" which are found inside the Star's orbital plane, near worlds. However, Pirate Jump Points can be highly dangerous due to changing influence a star's gravity. Typically only desperate spacers or foremention pirates would risk such a jump. Normally attached DropShips must detach from the JumpShip and undergo some cases days of travel to the interior of the solar system. JumpShips are limited to using station keeping engines, must not move due to economics of their constriction and their frailty. Jump Point of a Star is more economically better solar system, with space stations, notably charging station. Which collects solar energy from a large sail, like the JumpShip. This can almost instantly recharge a JumpShip, once it's moved by tugs to receive power directed from the station. Jump Points can be great distance form Solar System due to varying sizes of solar systems.[34]
JumpShip 
A form of Starship used by Human civilization in the BattleTech Universe. The ship final component of a 2 segment transportation system. They can not move quickly in normal space, require stay in area without any gravitational influences. These ships use massive amount power which they need to leap between measurement of distance to reach their destination instantly. However, they must use massive solar sails known as Jump Sail to recharge their batteries. Charging can a Jump Ship using the sail depends on the star, but on average 5-7 days. In some cases special batteries can be added to allow a double jump. JumpShips since destructive Era of the Succession Wars, JumpShips are fairly rare, near taboo to destroy due to loss of means building them in large numbers.

K[]

Kapteyn Accords 
See Concord of Kapteyn
Kearny-Fuchida Boom (KF Boom)
This is a part found on all DropShips. In short, this component allows docked DropShips to safely travel with a JumpShip in hyperspace. They act as external connector, that plugins into a DropShip when it connects with the Drop Collar of a JumpShip. Without KF Boom, drop ship would not travel through hyperspace and result in it's destruction once a ship jumps. Only Primitive DropShips lack KF Boom, must be docked INSIDE ships equipped with DropShuttle Bays.
Kearny-Fuchida Drive (KF Drive)
This is a large, cylinder like device made from titanium-germanium container with other electronics in side that allows for large spacecraft to jump into hyperspace. The device requires rare element of germanium, which is not easily cultivated/mined. Due to the nature of hostile universe BattleTech is, JumpShips became fewer during the Succession Wars Era, thus the titanium-germanium would be incredible valuable to what individuals can acquire raw materials, making them rich. The KF-Drive requires vast quantity to charge so it may open a hole in hyperspace. While travel in hyperspace is almost instantaneous, charging the KF Drive can take a week depending distant the from the sun a Jumpship need to collect solar energy from. Using Fusion Reactor about a ship to charge (Hot Charge) is possible and done in early age of exploration. Its not recommended, due changes of damaging the KF Drive. A charge from KF Batteries or / KL Batteries can provide safe charge for the Drive to be used.[35]
Kell Hounds (Mercenary Command) 
This is a historical and one the most revered of the mercenary companies that were formed in the 31st Century at the tail end of the Third Succession War. Formed by brothers Morgan & Peter Kell, cousins of sister-in-law Archon Katrina Steiner, leader of the Lyran Commonwealth, they were an elite mercenary unit whose exploits were well noted in the Inner Sphere for fighting smart and quick to adapt situations. Based on Lyran world of Arc Royal, the Kell's were part of the royal family whom ruled this world and eventually a region in later generations. Kell Hounds despite working for whom their contracted with, were always loyal to rightful rulers of House Steiner, eventually House Steiner-Davion. The company grew from 3018 to two Regiment force, whom has close ties to Clan Wolf-In-Exiles whom called Arc Royal home.[36]

This is a star cluster of settled worlds occupied the Clans. These worlds were originally settled by the SLDF, and however initial civilization collapsed due to ethic fighting, forcing son of General Kerensky to form the Clans and conquered these Pentagon Worlds and later expanded to habitable stars near the original Pentagons Worlds. Collectively, this region named for both Kerenskys and part overall region known as Clan Space.
Kerensky (Bloodname)
This was the surname of the founders of the Clans, Andery and Nicholas Kerensky. Like all Bloodnames, the founder names are earned through Trials of combat known as Bloodname Trial. Providing they earn proper degree of honor and do nor do they disgrace themselves; their DNA samplings are mixed with that of the founder and other Bloodnamed warriors of the same heritage of Kerensky, namely Andery or Nicholas. The bloodname of Kerensky is the most revered of 800 bloodnames of the Clans, since Nicholas Kernesky is the creator the Clans as well the first unified leader, the ilKhan.
Kerensky, Aleksandr
Last commander of the Star League Defense Force and the Protector of League during future leader Richard Cameron rearing. He would face the League's greatest crisis, where President Stefan Amaris of the Rim Worlds Republic would usurp the throne of the Star League and conquers it's core, the Terran Hegemony for himself with his nation's armed forces. General Kerensky leads the SLDF retake it, after being fooled into putting down a Uprising created by Amaris to lure the SLDF from Hegemony. After conquering Rim Worlds Republic, Kerensky would lead his forces in bloody campaign to retake Terra and Hegemony. However, the Hegemony in ruins, the Star League members voting to dissolve the Star League itself for their own purposes. Not wanting to risk greater war, Kerensky leads SLDF on Exodus from the Inner Sphere where he would found the Star League in Exile, which would sunder to political forces within SLDF and devolve into Warrior lead Clans after his death.
Kerensky, Nicholas
Son of Aleksandr Kerensky, and founding founder of the Clans. Because of his life experiences growing up as part child of general and resisting Amaris Empire on Terra, his brief tenure as officer in the SLDF in Exile, Nicolas in envisioned a society based on "Honor and Strongest Leads", using trial combat containing conflict between humans while regulating them into caste system. He accomplished this by reforming the former SLDF who followed him in 2nd exodus into society of Clans, lead by Warriors. He would designate himself "IlKhan", put end to the Pentagon Wars, home colonies of the SLDF had settled that turned to war. Its greatly suspected he himself suffered from mental illness and had engineered the Pentagon Wars to gain control and escape his father's shadow.

This a Clan designation of a formation intended for a Clan's senior leadership, its Khan and saKhan. These formations can vary in size, from Binary / Trinary to Cluster of troops.
KF Jump 
This is informal name for a JumpShip to make "Jump" to Hyperspace. A jump itself using the Kearny-Fuchida Drive for the occupants of the JumpShips is a brief operation. Jumps are essentially quick moves for a ship, as long there sufficient power for the KF Drive. Unlike other science fiction settings, Jumpships moves instantaneously from one place to another. Though gravity disruption can be detected upon arrival a ship from hyperspace.

This is the Clan organization which consists of a collection of fleet ships (warships, jumpships, dropships). Khanate acts as a Sub-Clan within a Clan. In canon, during the Dark Age Era, Clan Sea Fox was reorganized using Khanate, due to lack of worlds. These Khanate have their own Khan, referred to as ovKhan, whom answers to Clan's Khan & saKhan. Khanate can act on their own, growing, trade, they can add their own list of properties, by worlds, enclaves (city settlements) which are few on planets. Khanate are not strictly military formations, they are consist of it's labor/tech/science castes living on retired/converted JumpShips/WarShips/gutted DropShips into massive habitats they can cobble together. Khanate consist of five smaller fleets known as Aimag. They're warrior caste of a Khanate are arranged like traditional clan formations, but nothing larger than Clusters. Khanate takes the place of a Galaxy in Clan's Touman organization.[37]
Kindraa 
This name / designation for "Sub" Clan which is exclusively found within Clan Fire Mandrill. Due to the fragmented nature of the Clan, Kindraa are formed based on the Bloodnames leading it. Kindraa are typically named for the leading Blood House that leads it. Kindraa fight among themselves instead for whole of the entire Clan. This fragmented nature would lead to it's demised.
Kurita 
Family name of Ruling Family of Draconis Combine.
KLONDIKE, Operation 
Early Succession War Era military operation (war) in the Deep Periphery. The operation was when the first generation of the Clans, formerly SLDF, wage war against rebellious factions had formed in the original settle space of the Star League in Exile, Pentagon Worlds. This is operation where the Clans cement their control Pentagon worlds, placing the settlement in warrior-centric culture envisioned by founder Khan Nikolas Kerensky.

L[]

Land Air Mech (LAM) 
A LAM is a type of Mech which is uniquely able to reconfigure itself into a aerospace fighter and a hybrid of the two. They are extremely rare type of Mech which know how to build them was lost during the Succession Wars, with last vestiges of the type or ability to manufacture them ceased at the beginning of the Clan Invasion in early 3050s. Only Light & Medium Size BattleMechs could be built as LAMs. The type was actually removed from BattleTech due to lawsuits & game balance issues.
Landmine (Weapon) 
This is a autonomous explosive weapon typically buried underground to ambush unsuspecting troops. These weapons use pressure plates to activate once stepped on. The manner explosive varies in choices, from using non-lethal gases to knock out troops, to Inferno (fire explosive) type warheads. There large varies of of the Landmine used from anti-infantry to anti-BattleMech. Additionally there are sea based version of the mine, Sea Mine used for anti-ship/submarine defense. These weapons can be deployed by burying them by troops, using quick dispensary methods such as Thunder Long-Range Missile dispensers [LRM] (rockets crashing into the field), or special purpose-built vehicle normally referred to a Minelayer. Typically these weapons are used defensively of guard facilities or important locations which do not have enough defensive weapons. Minesweeper type equipment found on Combat Vehicles or firing Long-Range Missile Launchers into the suspected buried minefield will prematurely detonate these weapons. Enhanced versions of the landmine fired by LRMs are enhanced so they will react to targets more throughly. There is also version of the landminds that have command detonation via remote control radio signals or wired.[38]
Lance (Formation) 
This is smallest basic organized military formation for vehicles/mechs/aircraft found in the Inner Sphere based militaries. This consist of four combat units, BattleMechs, Combat Vehicles, Aerospace Fighters. The number of combat oriented units can vary, depending on their function. Basic Lance of 'Mechs or Combat Vehicles consist of 4, while Aerospace Fighters/Conventional Fighters only consist of 2, and is usually referred to as a "Air Lance". House Liao employs Augmented Lances, which six units with primary units and two supporting elements such as 4 Mechs, 2 Combat Vehicles or Combat Vehicles, Two Mechs.[39]
Lithium-Fusion Battery (L-F Battery)
The LF Battery is a powerful energy storage unit associated with JumpShips and WarShips. This battery can storage enough power to allow for a JumpShip to able to conduct a second jump into Hyperspace at a moment's notice. They require charge time same as it would be for charging a Kearny-Fuchida Drive.[40]

Star League military campaign during the Star League Civil War, which General Aleksandr Kerensky lead the SLDF reconquer the Terran Hegemony and dispose of "Emperor" Stefan Amaris.
Long Range Missiles (LRM) 
This a common direct-fire missile system found in use in the BattleTech universe. The missiles and it's launcher are typically referred to one in the same name. Commonly known as LRM, this weapon intended Long Range combat situation. Twin to Short Range Missile launcher (SRM), due to long range nature, it carries a less destructive warhead than it's Short Range variant, the SRM. However, the missiles are not exclusively fired from it's own LRM tubed launcher. They're are other launchers, typically multi-missile launching launchers (MML), Extended Rangee LRM [ELRM - Double range of standard model], Enhanced LRMS (NLRM) [Can shoot closer ranges, than standard model] and small man-portable launchers that can fire SRMs. There are different types of LRM missiles, some do not allow to be fired from its typical launchers (LRM-5, LRM-10, LRM-15, and LRM-20), and require a special launcher to be used. These Optional LRMs warheads include; (Clan) Streak Missile Launcher (Fire & Forget Launcher), One-Shot Launcher, Smoke (fired at ground leaving smoke provides cover from enemy fire), Thunder LRM (Deploys Minefield via Missiles.[41]
Loremaster 
This is the designated person who officiates Clan Ceremonies. They study the rules and judge trials and disputes.
Lostech 
This is term for any hyper advanced technology which was lost during the fall of the Star League and early Succession Wars. This technology ranged from typically battlefield weapons typically found on SLDF Royal Mechs, to type units, such as the WarShip, or the means to make such products such type mechs, or technology. Some more extreme cases such as ability to Terraform a planet into a habitable planet, or do things more automated. The Succession Wars as total warfare as it was, provide cover for ComStar to kill scientist to usher a new Dark Age. Their original plan was to have masses of humanity suffer technology loss so badly, that so they in turn could weight out as not even JumpShips could be made and the would take over all and save the InnerSphere as their saviors they would rule. This did not happen. Hidden bases or forgotten relics of the pass are found periodically, causing individuals to have advantage over others or become rich. However, ComStar during the Succession Wars Era, would quietly remove such items (capture, destroy, or even buy) hands of individuals, but not all.
Luthien 
Capital world of the Draconis Combine and House Kurita, it's ruling family. The world been nicknamed the "Black Pearl" due to the pollution of factories darkens it's skies in the past.
Lyran Commonwealth 
A major interstellar Nation of the Inner Sphere, located the northwest from Terra/Earth. A highly capitalist nation known to value wealth. Ruled principally by Steiner family. The Lyran culture has normatic/german influences. The nation was briefly known as the Lyran Alliance (3057 - 3081) after union with the Federated Suns ended as the Federated Commonwealth.
Lyran Intelligence Corps (LIC)  
This is a Lyran Commonwealth / Lyran Alliance spy organization used for intelligence missions including assassination against foreign and domestics threats to the Lyran homeland and it's rulership.[42]

M[]

Machine Gun 
Standard ballistic weapon used to kill infantry type and low armor targets. Unchanged from it's creations since the 20th century. Maximum range of 90 meters (3 hexes), these weapons are prone to causing the user mech being destroyed due to ammunition explosion. There are three variants of the standard Machine gun; Light Machine Gun (longer range, less damage), the Heavy Machine Gun (less range, more damage).[43]
Master Unit List 
Better known as the MUL, this is the official BattleTech online reference list to combat and non-combat elements (Battlemechs, AeroSpace Fighters, WarShips, Battle Armor, and anything vehicle wise.) in the BattleTech Universe. It is the official reference website for BattleTech when identifying, introduction dates, battle values of individual units played in the game.
Magistracy of Canopus 
This is a moderate size interstellar nation which lies south of Terra (Spinward) on the Inner Sphere's border with Free Worlds League. Established by individuals flee Terra during the Age of War Era, the nation became female lead nation. While free nation, the Canopus was known for it's medical and entertainment venues. Canopus is known for female angle leadership, it's military in early times (some cases still does) buy its ranks, but not often. Historically, Like all Major Periphery nations bordering the Inner Sphere, it was force to join the Star League in the Reunification War, where it forces were grounded down. It along with other Periphery States as they were known tricked into joining the Periphery Uprising to cast off financial burdens placed on it by the major states (Great Houses) of the Star League. Namely taxes and other economic concerns by Rim Worlds Republic. The Republic had created the Uprising, for it's own ambitions. Namely, it's leadership take over the Terran Hegemony and Star League by coupe. While fairing better than most Periphery nations, it along with the Inner Sphere would suffer from technological decline during the Succession Wars. By 31st Century, the Canopus's crafty leadership had join string alliances and established itself in larger role as it's ruling family married into Capellan Confederation's leaders creating strong bond. By the 32nd Century, the nation had also joined alliance in former Free Worlds League principality, Duchy of Andurien.
Maglev 
This is a form advance technology transportation found on some planets used to heavy materials or people on form of Magnetic track. This track allows the train to leviate about the track to allow for higher speeds than ordinary train or locomotive. This advance for of the train is highly expensive to maintain and only found few places in the Inner Sphere due to the destructive Succession Wars ravaging much of the human space higher grade of technology. They are found usually on key worlds where industrial need or capital worlds.
Manai Domini 
This was a an elite class of fanatical soldiers whom were in service of the Word of Blake. These were soldiers whom were cybernetically enhanced by with special and exotic technologies exclusively to them. These men and woman earn their spots by being maimed in combat in the service of the Word, being elevated and "Reborn" as Manei Domini soldiers. The group was originally special operations group operating in the early 3060s in the Chaos March region found in the center of the Inner Sphere. There in course years in secret they would learn their trade and expand their ranks to include using cybernetic enhancements from strength, hidden weapons, enhancements to their senses, bodies in some cases greatly changed, with abilities not possible for normal human, and most notably direct neural interfaces to control vehicles, mechs, battle armor and other combat related units with uncanning control. Unlike normal humans, its believed these cybernetically enhanced troopers have a short life span but, this is unclear. These soldiers would emerged from secrecy at the dawn of the Jihad, formally organized into their own Divisions of frontline but elite combat formations. They would further enhance the capabilities by having their own dedicate series of OmniMechs, Battle Armor, Aerospace Fighters, and Combat Vehicles. Unlike other Word of Blake soldiers, the Manei Domini answered only to individual known as the Master. The Master, formerly Thomas Marik, whom was secretly kept his real identity secret, with substitute agent masqueraded as him in public and ruling the Free Worlds League in his steed. The Manei Domini reign fear down on all who opposed them, viewing normal humans as "Frails" They would allegedly meet their demise as organization by end of the Jihad War in 3081. With many who remained hunted down, while others disappearing along with portion of the Word whom had not been ousted from the Inner Sphere and killed.[44]
Marik 
1) Ruling family of the Free Worlds League, better known as House Marik. 2) Nickname for individuals hailing from Free Worlds League.
Maskirovka 
This is the name of the Capellan Confederation's spy agency. Russian word that translates into English as "disguise".
Mech 
Slang for BattleMech, OmniMech, or a civilian IndustrialMech.
Mech Bay 
This is formally known as a BattleMech Bay or Repair Bay. This is found in range of locations, usually a fix structure found from DropShip's bays dedicated to 'Mechs, Repair Bases where technicians have dedicated tooling and supplies to totally restore, rearm, reconfigure, or fully repair 'Mechs. These bays have gantry that towers as tall as 14 meters however, some sizes vary. Other repair bays are mobile vehicles as well.
MechWarrior 
The official title of individual who pilots a BattleMech or OmniMech for combat purposes.
MechWarrior: Dark Age
This was a collectable game miniatures tabletop game devised by WizKids in 2001. The company was founded by BattleTech co-creator Jordan Weisman. The game was set in 3132 in the BattleTech universe, was largely a new time period yet explored by the original game line which was frozen in 3067. Weiseman revived original Battletech tabletop game, allowing it to continue. Game would cease being made by bankruptcy of the company however, the original Tabletop game would continue and move into the what term as Dark Age Era (3085-3150) time period and absorbing much of miniatures and fiction MWDA game created.
Medium Range Missile (MRM) 
Better known as the MRM, this a brute force style missile launcher. Developed by the Draconis Combine in 3050-3060s, these weapons were intended to bridge gap between ranges LRM & SRM launchers. Unlike the older weapons, MRM have large volume of missiles that can be fired per volley. MRM launchers are arrange of tubes of 10 (MRM 10, 20, 30, & 40), if not counting Battle Armor/man-portal launchers. These smaller launchers have less tubes than vehicle/Mech type uses. Unfortunately, the trade off for large volume of fire is accuracy. Where percentage shorts fired tend to miss unless enhanced by a Apollo Fire Control System which cuts down shorts miss and difficulty to hit.
Memory Core 
This is a piece of technology developed by the Star League. Officially known as a Star League Memory Core, this device is form of computer memory used to store all the technology, research, knowledge of all types, and other assorting information related to the League. Due to League's destruction, technology was lost due to wars of the Succession War Era, which was secretly pushed by ComStar, whom destroyed memory cores when they were uncovered to prevent technology (lostech) being recoverd so they could ultimately dominate the Inner Sphere, reforming the Star League in manner they wished. However, in the 3028 a memory core was discovered and it's contents of lost technology was spread across the known Inner Sphere reviving it's technology base. Three memory cores had been recovered in canon history, including 3028 discovery known as the (named for world it was found), Helm Memory Core. Others include; New Dallas Memory Core (which notablly revealed ancient technology & designs forgotten the Inner Sphere) and Graus Memory Core, recovered prior to the Clan Invasion.
Mercenary  
A soldier for hire, whom can acquire great wealth. While individuals can freelance their services, typically they form mercenary companies (organization / business vs size of force). Also known as Mercenary Commands, these companies can formed around any type of military machines such as; combat vehicles, Aerospace Fighters, Dropships, and However, more so commonly companies consist primary of BattleMechs. These companies can grow as large from 4 unit Lance to rare multi-regimental size brigades. Mercenaries can under take missions an potential employer may need, typically choosing these missions by "neutral" parties such as the Mercenary Review Board sponsored by large organizations or national interests. The latter is dangerous, such as nations try to permanently attain the services for mercenaries by making them in-debt to the employeer via "Company Store". The "Store" tends to easier mean to access replacement parts and equipment, but with loans which can easily bankrupt the company.
Misjump 
This is a result of accident accruing when a JumpShip is making the jump to Hyperspace. A misjump can result in injury to the ship's crew, navigational displacement of vessel through hyperspace in completely different starsystem not planned for, minor to catastrophic damage to the jumping ship, and rare and dreaded cases, the destruction of the ship. Typically it is a navigational displacement, however, multiple things mentioned can accrue at same time.
Multi-Missile Launcher (Weapon) 
Communally known by it's abbreviation as MML, the missile system is a fusion of both Long-Range (LRM) and the Short-Range Missile Launchers (SRM) used in the Inner Sphere. The system is designed to take combination of both systems and fuse them into a system that can switch from one kind of launcher to another. The system was intended cut down number different kinds of lauchers. However, they are heavier than their original cousins and require separate ammunition bays per type of ammo required. The launcher allow for firing of any type special ammunition barring need for guidence system such as Artemis IV which needs to be added on. Streaks ammo types cannot be used in MML nor can torpedoes which both require specialized purpose-built missile launchers. There are four size (missile tubed) launchers available for the MML; MML-3/MML-5/MML-7/MML-9.[45]
Myomer 
This is a artificial muscle which are used in 'Mechs, Battle Armor, and medical applications such as replacement limbs for people.[46]

N[]

Narc Missile Beacon 
Homing system which comes in a form of a type missile launcher/missile system. When a Narc missile strikes it's target, it acts as a radio beacon to draw in specialized long-range missile (LRM) ammunition to increase probability of the them to hit. Ammunition used can also feature an explosive verses a non-damaging homing device. Guardian ECM Suite can jam the signals of the Narc however, does not prevent the variant explosive type from detonating.[47]
Naval Autocannon 
Naval Autocannons (abbreviated NAC) are form of ballistic weapon used by large spacecraft and large planetary defense batteries. The weapons are the among most powerful ballistic type weapon used, typical for WarShips. Their destructive power is 100 times more than typical weapon found in normal BattleTech on a BattleMech. Example: AC/10 (Autocannon 10) does 10 damage to standard armor, while Naval Autocannon / 10 does 100 damage. These weapons are typically larger than anything a DropShip or smaller could ever hope to mount. There are five classes of these weapons used; NAC/10, NAC/20, NAC/30, NAC/35, NAC/40.
Needler 
This hand weapon used kill unarmored persons. The weapon uses chunks of plastic, which it fires high velocity at the target in shreds. These shreds of plastic will tear a human flesh on contact. It useless against anything armored.
Neg 
A Slang found in Clan culture for Negative, which was originally a military term for No.
Neurohelmet 
This is a helmet used by MechWarrior to allow a BattleMech and other vehicles to take advantage of a Human's sense of balance to allow it move with more accuracy. A neurohelmet uses person's inner ear/sense of balance for any kind of 'Mech from not falling over while moving. This operates in addition relying on using a Mech's Gyro. These helmets are bulky and are placed over the shoulders as well as the pilot's head. These helmets have been known to be used with pilot of other vehicles such as AeroSpace Fighters.[48]
New Avalon 
The capital world of the Federated Suns. Seat power of its ruling family, House Davion. It is the home of the nation leading research school, New Avalon Institute of Science, factories that produce Legionarie and the Valkyrie BattleMechs among other things. Mount Davion found in the old capital of Avalon, was military headquarters of that coordinated the Sun's military forces, better known as the "Fox's Den" in early 31st Century until it's destruction in 3070s by Word of Blake.
New Avalon Institute of Science (NAIS) 
The is the arguably the most prominent leading school & research facility of the Federated Suns. The Institute (better known as the NAIS), has been was founded by Hanse Davion in early 31st Century as part the effort to recover Lostech and innovate resurgence new technologies to help people of the FedSuns.[49]
Niops Association 
This is a tiny space nation lying on the edge of the Inner Sphere. The single star periphery nation is noted for being hold out colony of the original Star League, having retained much of the the scientific knowledge lost during the Succession Wars, while avoiding hidden agenda of ComStar to eliminate all high technology for their long term plans to "save" the Inner Sphere from itself with their secretly long held knowledge of Star League Technology. Individuals from the Association are referred to as a Niopian. The Niops however is resource poor nation, never employed anything larger to be a threat or to spread technology it long since held.[50]
Nova (Clan) 
1) (Military Formation) This is a small Clan combined arms formation where two different types Stars consisting typical of BattleMechs/OmniMechs and Elemental Battle Armor are assigned together. This type formation is commanded by a Star Commander (sometimes referred to as a Nova Commander or Nova Star Commander) This formation trains to work together support each other in combat. Larger version of this formation is known as a Supernova. 2) (OmniMech) The Nova is the Clan name for a medium OmniMech, which was renown for it's armed mounted weapons and maneuverability. While popular, it's production facilities had been captured by the 29th Century, their numbers would drop to unmaintainable levels by late 31st Century during the Clan Invasion Era. However, by the 3070s, during the Jihad War, a non-Omni/non-modular version of the Mech would be placed into production, however not as flexible as the original.
Noteputer (Device) 
This is BattleTech universe of a combination of a Laptop & Tablet style portable computer It used used for administrative purposes (office work). [Note: BattleTech invented this device before the concept of small portable computers existed.]

O[]

Occupation Zone 
This is the designation for area of space control by a Clan after the initial invasion of the Inner Sphere in 3049. These areas are found Spinward from Terra. Originally known as Invasion corridor.[51]
OmniFighter 
These are highly modular version of the AeroSpace Fighters. With alotted tonnaged dedicated to weapons or specialized equipment for their choosen missions. Similar in nature of modularity to the OmniMech, these modules are referred to OmniPods. Unlike conventional vehicles, refit to different "Configuration" suiting the missing, only takes matter minutes than hours or days.
OmniMech 
This is modular version of the BattleMech. Where refitting changing out weapons and equipment on a BattleMech means redesigning the Mech, taking considerable amount of time to do. OmniMech uses OmniPods which are containers that allows weapon or equipment plugin into the OmniMech in short amount time. Typically due to balance issues (weight or game balance) OmniMechs usually patterned amount of "configurations" weapons usually found on a OmniMech per model or class of mech. OmniMechs themselves, have fix amount of weight of Podded equipment they can carry based on their size and allotted room. Equipment that cannot be moved, that is permanent to the OmniMech is usually referred to fixed equipment. OmniMechs are knowns to require more maintenance than normal BattleMechs (this was game mechanic to balance out differences between OmniMechs and standard BattleMechs.)
OmniPod (Technology) 
This is a form of modular equipment that's contained inside a "Pod". These Pods allows for weapons and equipment to be easily added to vehicle/'Mech/Aerospace Fighter which was designed to be modular. Purposes of OmniPods for the easy customizing or changing out needed weapons to suit the mission or easy repair/replacement damaged ones. Such Units are designated with word "Omni" on them, such as; OmniVehicle, OmniMech, OmniFighter. The technology is design for technicians to install desired items into a unit. Limitation is the weight capacity a chassis to receive Omni-Pods. Example a Tomahawk II Assault OmniMech, whose chassis capacity is 56 tons. Thus 56 tons of weapons and equipment can be placed in pods and mounted where ever there is pod fitting on the 'Mech. Typically, this the arms, legs, torsos, and sometimes the head. It is standard naming practice to have any given unit's primary weapon/equipment load out (Most common) to be designated as the "Prime", differentiating weapons/equipment load outs are known as "Alternate Configurations". Standard units (regular construction) call their related designs variants, but these can not be changed unlike omniMech. Omni-based vehicles are known to require higher maintenance and cost. <Wiki Note: <This was done for game balance purposes, so not to obsolete standard built units in BattleTech>[52]
OmniVehicle 
This is modular version of the Combat Vehicle. They are like other Omni-based vehicles able take various modules containing weapons, equipment, sensors, engine enhancements, based on allotted amount of carrying weight they have and room for critical component slots.
Outreach 
The famed world of the Wolf's Dragoons during the 31st Century, which during their rule during the century prior to the Jihad, was a mercenary world. A place where mercenary soldiers make contracts and sell their services to any who wish to hire them.
Outer Reaches Rebellion (Event) 
One of the earliest events of Age of War prior to the Inner Sphere nations having to form. Due to over taxation of world of Freedom, the Outer Reaches Rebellion would turn into out right war (2236 - 2237) when the Terran Alliance needed to put down rebellion down. Other neighboring colonizes hear the plight of Freedom began rebel as well. Poorly armed colonist began inflicting heavy causalities against the Alliance troops due to unorthodox tactics and aid from various parts of colonized space. By December 2237, the Alliance's political parties squabbled, with the Liberal Party blocking military funding for the war from the Expansionist party. Ending the war by attrition of the Liberals. The wake of this political squables would lead to the Terran Alliance with drawing all support to colonized space and leading to creation of the modern nations of the Inner Sphere but not without great suffering and failure of many colony worlds whom were dependent on the Alliance support to survive.[53]
Outworlds Alliance 
A periphery nation situated on the Draconis Combine & Federation Sun's joint border. A pacifist like nation, which invests in AeroSpace Fighters more than BattleMech forces due to their nature wish only to defend and not invade. They were best known for having the best AeroSpace Fighter pilots in the Periphery and Inner Sphere. They would be later taken over by the late 31st Century by Clan Snow Raven in a forced merger of two groups, with the Snow Ravens best known for one of the "naval" focused Clans among Kerensky's Children.

P[]

Periphery 
Region of Space that borders the Inner Sphere, where host of smaller nations or independent worlds exists. Largest of these nations were the Rim Worlds Republic, Magistracy of Canopus, and the Taurian Concordat. This region is regarded backwater of humanity, with less technology advanced and wealth in comparison to the nations residing in the Inner Sphere.
Periphery, Deep 
The Deep Periphery is largely unexplored region of space far from the settlements of humanity in the Inner Sphere. However, some established powers have settled some places such as the Clans's Kerensky Cluster & Pentagon Cluster. Other minor periphery powers have also settled in the Deep Periphery to avoid the repeatitive and highly dangerous conflicts in the Inner Sphere, such as the Hanseatic League.
Periphery Uprising (Event)  
Sometimes referred to as Periphery Rebellion, this was a historical event which was staged during the last years of the Star League Era in 28th Century. The three of the four major Periphery States of the Star League would secretly be supplied weapon and means to restore their militarizes try rebel against unfair taxing and unfair treatment they have received form the major Star League Member States, aka The Great Houses. However, rebellion was a ruse to draw away the SLDF from the League's central nation, Terran Hegemony, and force them to send entire Star League Defense Force. The Rim Worlds Republic would use this as means to stage a Coup and kill the Star League's leader, Star Lord Richard Cameron and cease control of the League itself installing the Republic's leader, President Stefan Amaris.
Pentagon Civil War (Event) 
This was conflict fought by five original worlds settled by the SLDF in region known as the Pentagon Cluster in the Deep Periphery. War was fought by ethnic groups who were reclaiming their old Inner Sphere heritage. The chaotic conflict forced the majority of the armed forces of the SLDF retreat to Strana Mechty, one of the then colony worlds This retreat was called the "Second Exodus" which was implemented by Nicolas Kerensky. The War provide a convenient means for Kerensky reform Star League in Exile into the Clans. As the Clans were forming, the Pentagon War fragmented society greatly on the 5 worlds of the Cluster, reducing them to mix of primitive technology and warring states. The situation would not be resolved until the Clans had fully formed and returned invade and force Clan way of Life on to the people of the Pentagon. Its suspected that the war itself was engineered by Nicolas Kerensky.
Pentagon Worlds (Place)
Sometimes referred to as the Pentagon Cluster, these worlds are located in Clan Space. A cluster consist five worlds, which were first to be settled by the Star League in Exile lead by SLDF Commanding General Kerensky. Majority of the population of the Exodus Fleet of the SLDF settled on these five worlds. Over course of years, wars broke amongst the settlers forming mini-factions modeled after the nations of the Inner Sphere. This lead to the creation of the Clans, whom returned after twenty year absence and conquered the worlds and modeled them after their new Clan system.
Pilot 
1) A person who pilots a air vehicle of some kind. Usually small vehicles, not large Aerospace DropShips or larger vessels, whom are simply crew. 2) Clan geneo type, person who was genetically modified from their artifical birth (Iron Womb) to tolerate riggers of piloting a air or space small vehicle. These individuals are usually shorter in height and have slightly bigger heads which this physic allows them tolerate gravity or G forces high speeds. However, it's been shown pilots aren't as superior to normal human pilots. Typically Clan pilots whom fail their Trial of Position can still become a ground based Warrior / Pilot. After passing second Trial, they can end up prepared to use a ProtoMech. This is 'Mech like Unit which is less than 15 tons. However, a ProtoMech Pilot must undergo surgery with special implants so they may control a ProtoMech with their minds. However, the combination of using surgery and special medications shortens their lives.
Pirates 
This is a group / faction that exists in the BattleTech universe. They are raiders, whom are considered be thieves, killers, lawsless individuals who attack worlds for resources, wealth, slaves, and illegal mercenary work. Unlike classic sea going pirates, they are not limited to spacecraft. Their typically known to be more form of raiders, whom do not work for any recognized official faction. They are best known using BattleMechs when attacking worlds, stealing what they can. They are sometimes former military units gone rogue, wanted individuals whom are not able to hold job. They are the most ruthless of factions in the BattleTech universe, with no morals. Like any illegal factions, they are typically hunted down by contracted or nationalize forces to restore peace. Pirates usually operate as bands, groups of individuals working for Pirate Captain or with larger formation "Lord". While not typical, pirates seldom have lands of their own. However there are some from single, to multiple world named nations which are havens or run by these pirates.
Pirate Point 
This is navigational reference used for Hyperspace travel. A Pirate Point is a unstable location inside the gravity well of a solar system for a JumpShip to move to that close to a planetary body, such as a planet or other locations. This hazardous location inside a solar system go to due to the potential of the gravity of planets, moons, the stars in the system could destroy the a JumpShip. Usually pirate points allow for vessel's smaller ships such as DropShips to days to weeks off their trip inside the solar system. Pirates tend to use these unstable Jump Points quickly go in and out of a target with less chance being intercepted by opposing forces.[54]
Point (Clan Formation) 
This is smallest organized group of Troops used by the Clans. There are part of a larger formation called a Star and 5 points may be attached to a Star. A Point depending on the type of unit/troops it consists of; single 'Mech, two AeroSpace/Conventional Fighters craft, 25 conventional infantry lead by a Point Commander, two Combat Vehicles, Single DropShip/JumpShip/WarShip, or prominently team of 5 Battle Armor, lead by officer known as Point Commander.
Point Commander 
This is a Clan officer, whom is in charge of a Point formation of Clan troops. This is lowest officer rank in the Warrior Caste of the Clan's military. Basic Troopers, Battle Armor Troopers, Combat Vehicle units, and Aerospace Fighter Pilots report to the Point Commander, while the Point Commander reports to the Star Commander.
Power Armor 
This is the militarized version of the Exoskeleton-suit, a machine that human wears to enhances their physical strength and allows them carry additional equipment normal soldiers are not able to wear. Power armor are lighter and less bulky than Battle Armor which are uprated and more advanced suits in comparison to the power armor. Power Armor is also referred to as PAL (Power Armor, Light). Typically these suits are used in infantry formations to enhance their performance, and prove to be less expensive and more flexible in some cases to the Battle Armor. They usually do not have integrated weapons, sometimes has Jump Jet fitted to them.
Primitive 
This is label used for outdated & obsolete technology. At first when introduced, they were and still are superior to anything that came before them as far combat firepower and abilities. However, when technology found in the 25th Century and beyond was introduced and became "Standard" Technology, this early generation of 'Mechs, Weapons, Armor, Vehicles, and so forth would end up being referred to Primitive (Unit type). Example; 'Mech made with Primitive Technology, is referred to as a Primitive 'Mech. Ths is due to modern 'Mechs are superior in every aspect including engines, heat absorption, weaponry and so forth. Many these "Primitive" type technologies would be become "Commercial grade", be used for other proposes.
Primitive JumpShip 
This is an obsolete form of the basic JumpShip. These vessels, like regular JumpShips are able to move between the stars. However, unlike modern JumpShips, they are hybrid of both WarShips and what became JumpShips. These craft infact have Interplanetary Engines, allowing them move to planets or other bodies within the Solar system, however at great cost. Increase range of it's KF Drive requires to use more space than modern KF Drives. These ships typically have no Solar Sails or Drop Collars, which permitted externally docked DropShips to dock & jump with the ship into hyperspace. Smaller, more primitive types of DropShips, known as DropShuttles would need to dock inside a Primitive JumpShip so to be transported. Primitive JumpShips had very limited range, from 15 to 25 Light Years depending on size. Like all Primitive Technology based vehicles, the Primitive JumpShip would suffer from obsoletion due to cost to maintain a vehicle no longer in production. Example of a Primitive Jumpship is the Aquilla. As of this writing, there no stats for a armed Primitive Jumpship setup for combat. This is due to decision made in fictional background of BattleTech.
Protomechs 
This unique type of 'Mech which are economically small in comparison to 10 to 13 meter tall BattleMechs. A Clan type of Mech, not unlike Ultralight BattleMech in weight. These Mechs can range from 5 to 15 tons. With any ProtoMech 10 tons to 15 tons are considered to be "Ultra Heavy". The heaviest of ProtoMechs are nearly on par with the abilities and firepower of a light BattleMechs. Their potency in combat is due to their nature, they may strike singular target in groups consisting of Points. Warriors whom are recruited to use these machines are typically ones who failed pass their Trial of Position to become a Pilot. Those whom pilots of these machines require special surgery and special cocktail of drugs allow them to interface with these mechs. When used by the Clans, ProtoMechs operate in groups of 5 in formation known as Point, like Battle Armor employed by the Clans. While inexpensive, these 'Mechs are unpopular due to shortening of the lives of the pilot and psychological issues they develop.

Q[]

Quiaff (Term)
Clan slang term used to ask for positive confirmation, similar to adding "yes?" to the end of a sentence, originating as a portmanteu of "query affirmative?". For example: "These pirates are unworthy of zelbrigen, quiaff?"
Quineg (Term)
Clan slang term used to ask for negative confirmation, similar to adding "no?" to the end of a sentence, originating as a portmanteu of "query negative?". For example: "It is strange that we of the Clans do not use contractions, but portmanteus are acceptable, quineg?"

R[]

Rasalhague Dominion
The Dominion is a fusion of both a Inner Sphere nation "The Free Rasalhague Republic" and Clan Ghost Bear. The Republic was invaded in 3049 by Clan Wolf & Clan Ghost Bear in the part of the Clan Invasion of the Inner Sphere. The Ghost Bears being enlightened to it's new Inner Sphere citizens, allowed more freedoms than most Clans occupying the Inner Sphere. By 3060, the Ghost Bears Occupation Zone became the Ghost Bear Dominion, showing signs of progress/change in the the Dominion as it was called, with Clan leadership governing it still like has been with Clans. In 3070s as the Jihad War raged with the Word of Blake, Remains of the Free Rasalhague Republic was attacked, which triggered the Bears to invade and invite the Republic back with it's kin in more formal merge. The Republic agreed, over course war up to 3090s the Dominion make up would change. 3101 would mark nation change to the Rasalhague Dominion, with fusion council of lower castes, politicians of the Rasalhague citizenry and Clan Ghost Bear's warriors. The Dominion very defense nation, only waring when it needs to. Many times having wars with Draconis Combine whom still has conservative elements wishing to reclaim former Combine worlds from the Dominion.[55]
RAT, Operation (Military Operation) 
This was the code name for the Federated Sun's military operations in their invasion of the Capellan Confederation in 3028 for war later named Fourth Succession War. This operation would prove to be successful, severing the Succession State in half. Limiting it means to build / rebuilt its military forces and threaten the new Federated Commonwealth posed to form.
Raven Alliance 
This is a hybrid nation state in the Periphery bordering the Draconis Combine and Federated Sun. Formerly known as the OutWorlds Alliance, the aerospace oriented and low-tech pacifist state merged with the Clan Snow Raven. The two became slightly uneven hybrid nation with the Clan leading them. Specialized in Naval & Aerospace warfare, the nation weak in combat on the ground. The Remains of the OA's ground forces were used as planetary guard forces, while the Ravens for the most part focus on the air. The nation formed during the Jihad in the 3070s. The Snow Ravens themselves since then, shown their management would be poor of the former Alliance worlds and later conquerored Draconis Combine & FedSuns planets, being poor resource wise.
Reaving (Term)
1) This is the Clan terminology for removing Bloodnames warriors and their generic heritage. In some cases killing any gene-children (artificially created children descending from the warrior) to "purify" whatever crime or flaw a faction has deemed intolerable. This is a grave action for any Clan to undertake, highest of crimes. Only the original blood named warrior/founders would be left intact or any before the subject cause of the reaving.
Recognition Guide 
Recognition Guide (RG) is Clan name for the Technical Readout publication used identify combat & civilian machines/mecha/vehicles/etc in the BattleTech Universe. The term was first introduced at beginning of the IlClan Era. Published by Clan Sea Fox in 3150, at the dawn of the invasion of Terra.
Refusal War (Event) 
The Refusal War was a Clan conflict that accrued in the Inner Sphere between Clan Jade Falcon & Clan Wolf in 3057. A destructive conflict fought to prevent Clan Jade Falcon from prematurely restarting the Clan Invasion after years of frustration. The conflict would leave both clans depleted, with segment of Clan Wolf going into exile to the world held by Inner Sphere, becoming Clan Wolf in Exile. Clan Jade Falcon would be in ruins, claiming "last" Clan Wolf Warrior, Vlad Wolf, as bondsman in ruins. It would turn out that Jade Falcon's Khan political underhandeness would lead to resurrect of Clan Wolf for his own plans as "Clan Jade Wolf" with majority of the former Wolves in it. However, Vlad Wolf would take a Bloodname and kill Falcon Khan due to his deceit and murder of Ulric Kerensky, ilKhan. Ward would resurrect Clan Wolf, but posted to enemy of the Inner Sphere.
Regiment 
This is a large military formation, where units within this formation number (108 BattlMechs or Combat Vehicles). Usually formation this size require at least 4 assault size DropShips to transport, such as Overlord-Class DropShip.[56]
Regimental Combat Teams (RCT) 
This is a large formation of Regiments teamed up serving as one entity. Originally RCTs consisted or four Regiments, 1 consisting of BattleMechs, other consisted of Combat Vehicles/Armor Formations (Tanks) and supporting elements of transportation & supplies. Federated Suns would create new model of RCT which would be common in the Inner Sphere in the 31st Century, consisting 1 Regiment of Mechs, three Regiments of Combat Vehicles, five regiments of Infantry, two Aerospace Fighter Wings (36 fighters each) and battalion of Artillery. Further RCTs would be changed and refined as newer combat units, such as Battle Armor is introduced.[57]
Remembrance 
This is a living document of history maintain by each of the Clans of Kerensky, better known as the Clans. The document is not unlike epic poems maintain by ancient Vikings of Europe, which chronical the history of a clan with entries of heroic deeds and other assorted events a Clan experiences. Warriors and potential warriors are required to learn this document. To have entry of one personal deeds is considered a HIGH honor among the clans, next to passing a individual DNA to make next generation of Warriors. Many who are unable to earn Bloodname, are just as honored to be remember of their own actions in their Clan's Remembrance. The document is maintained by a Clan's Loremaster.[58]
Rendering 
Alternate Clan name for a Civil War, which Clansman have cultural issues using this name. Example of this is during the 3136 when Galaxy Commander Malvina Hazen fought Khanship from sitting Jade Falcon Khan, Jana Pryde in 3136.
Republic of the Inner Sphere 
This is a nation that was formed after the defeat of the Word of Blake in 3081. Formation of the Republic came about by the influences of David Lear and Devlin Stone, the general whom lead coalition forces to defeat manic Blakist. The Republic in the canon universe stood from 3081 to 3150. They were largely free and capitalist multicultural nation, which was twp branch government of Senators and Paladins whom all answered to the Exarch. Elements people of all factions in the Inner Sphere would join the nation until it's demise at hands of the Inner Sphere based Clans.
Reunification War 
This was first war fought by the Star League between the years of 2577 - 2597. The conflict was part efforts of the Terran Hegemony's Lord Cameron using the conflict against the Periphery States to unify the League. Initially Periphery was high resistant to being forced to join the Star League, seeing no benefit of the union. As weak attempt to resist, they formed loose alliance known as United States of the Periphery, consisting of the Taurian Concordat, Magistracy of Canopus, OutWorlds Alliance, and Rim Worlds Republic.

However, the base line chassis is called "Standard" or "Standard Structure", while on flying or Aerospace vehicles is refer to as Structural Integrity (SI). Difference is how much weight for it allowed on the vehicle (Parts of the vehicle) and how much durability vehicle can take if damage destroys a vehicle/mech's outer armor. There are different types of chassis; Standard, Endo Steel (more weight, less room for parts), Endo Composite (Better weight savings, takes less room, however more expensive, rare, availability varies from Jihad/Dark Age Eras and beyond), Reinforced, and Composite (Lightest, takes less room in criticals, double damage when hit directly.)

There were four wars which this time period gets its name, while smaller conflicts are also fought before end of the 3049, when the Clans invaded the Inner Sphere.
Succession War, First 
This was first war of the Succession War era, where all five remaining Star League member state, at the peak of the their military build up and technology unleash total warfare against each other. This would the conflict where brutal strikes each other left millions dead from worlds being annihilated from devastating planetary bombardments and use of nuclear weapons. By the end of the conflict a considerable amount of factories are destroyed and technology levels of all the combatants begins to slide downwards, with countless millions dead on all side, what was former Terran Hegemony lay in ruins as mass land grab among other moves.
Succession War, Second 
Mere decades after the First Succession War, the Second would begin. The remaining forces with enough military strength and consternation Star League level technology is thrown in to final throws of battle for domination in effort try make gains before the mighty nation is expended. This is era where Star League technology levels would go extinct, where last of the Inner Sphere's WarShips would be lost in efforts hold one another off from tipping tables to the other winning a conflict before troops make their land fall.
Succession War, Third 
This is a war would lasts centuries. However, during this time period, the Inner Sphere's Succession States as they would become to be known as would only periodically muster enough BattleMechs and troops to casual raids for resources and rarely launch massive invasion troops mustering beyond a Regiment (105 BattleMechs). Considered to be raid wars, where only company of 12 'Mechs would use try to acquire fleeting resources found and ever increasing rare technology.
Succession War, Fourth 
The final Succession War in name and the shortest one, with war being fought from 3028 to 3030. This would be war where Federated Suns and Lyran Commonwealth would commit to alliance to merge their states into nation not seen since the fall of the Star league. Where they would Federated Suns conduct massive invasion into the Capellan Confederation and Lyran Commonwealth would move towards Terra cutting into the Draconis Combine and Free Worlds League where they would secure the borders between the two nations. The three other Succession States having formed an written document forming alliance known as the Kapteyn Accords, failed to work together to prevent Federated Commonwealth from forming, resulting Capellan Confederation being cut in half, leaving the Free Worlds League in chaos.
Successor States 
The Successor States (named as such due to their being the "Successors" of the Star League) are the major military powers of the Inner Sphere, each governed by one of the Great Houses and with its own customs and culture. After House Cameron was wiped out in the Star League Civil War, the five remaining Great Houses spent the next several centuries fighting each other to determine who would succeed as the next First Lord. By the 31st century the Successor States found themselves bloodied and no closer to their original goal when the Clans invaded. In response to this new threat the Successor States set aside their differences, eventually forming a Second Star League to beat back the invaders. This peace was only temporary though, and with the dissolution of the second Star League the Successor States have continued their struggle for dominance into the 32nd century.

Supernova (Clan) 
1) (Formation) - A Clan Supernova, is a military formation that combination of two Nova formations. This usually replaces a Binary or Trinary formations. Supernovas center around a Binary Star of Mechs to form a larger combined arms group.

As with novas, Supernovas are not restricted to just Battle armor and Mechs, while they can include Combat Vehicles (10), Aerospace Fighters. Or truly mixed Star which its Points included completely different units, such as ProtoMechs, Battle Armors, Combat Vehicles. Usually such a mix relays on more Omni-design machines that can help provide organic transportation for the slower units. A Keshik or a Galaxy's command formations are usually Supernovas. 2) (BattleMech) A Supernova is a assault size BattleMech, designed during the 29th Century, with large array of ER Large Lasers.

Technical Readout 
This a type of in-universe publication (actual table top published source book) which acts as a guide to civilian & combat units ('Mechs/vehicles/aerospace/battle armor) that appears in the BattleTech Universe. These guides, are published names are traditionally use game year or Era its representing. Example "Technical Readout: 3025" or "Technical Readout: Succession Wars". Some specialty publications of this kind do not use year/era reference as part of their name, but by what focus of the publication. Such as "Technical Readout: Vehicle Annex" which specialized on civilian type vehicles or secondary vehicles on frontline combat units.
Technology 
BattleTech organizes Technology in game levels (which changes per Era due to the length the game's universe history), which extends over a 1000 years. Two major meta group factions have their own technological levels, the Inner Sphere and the Clans. However, technology is also different per time spans / eras and is measured as such. There are four official technology levels and one unofficial. This is breakdown of these levels. It should be noted that, game since forming 1985 has different ways measuring technology. These technology level were setup and reflect game rules of what grade of equipment could be used. Please see the canon wiki for more details on the subject Technology Levels and here for Rules Levels. Below is breakdown on basic current groupings.
  • Primitive Technology - This is beginnings of galactic wide technologies, still more advanced in some cases from 20th Century Earth. Primitive describes technologies and equipment (mainly military) which are the prototypes to technology found in modern eras. Primitive also can be classified as Industrial/Commercial since its used by civilians verse military. Early AeroSpace based vehicles, ground based vehicles including 'Mechs of both Industrial & Battle variety, as well early weapons. Many these weapons are also prototypes which have negative effects or less than effective abilities. While not cutting edge, this technology is also classified as Experimental Technology.
  • Standard Technology - This is sometimes referred to as Level 1 in older rules, this is better known as Inner Sphere Standard or Inner Sphere Technology. This is baseline technologies used during the Succession Wars Era and during the earlier Age of War Era. Technology here is baseline used in the BattleTech as of game year 3025 till 3050.
  • Advanced Technology - This is higher grade of weaponry which is by all counts cutting edge. Both only available in limited numbers or have high cost in currency or game Battle Values. WarShips are considered to be Advanced Technology in the game due to difficulty building them and the technology used to make their Interplanetary Engines.
    • Clan Technology - Clan Technology is superior to the Inner Sphere's tech, like Inner Sphere Advanced, Clan Technology Advanced is has limited availability while virtually impossible to obtained by Inner Sphere factions in 31st Century when Clans first appeared. This is technology solely developed by the descendants of the SLDF based on older Star League Technology. Noticeable Improvements include; Increase range of weaponry, better accuracy, decrease weight weapons & equipment, clone/bioengineering technology (Iron Wombs) creating /improving humans soldiers, further development of Power Armor into Battle Armor, Modular designs for Weapons & Equipment ("Omni-Pods") for vehicles/Mechs, and limited self-repairing technology called Harjel as examples.
    • Star League Technology - Star League Tech was form of advanced tech only available to the Star League and later ComStar until the 3040s when Helm Memory Core was discovered allowing Inner Sphere factions once again access to Advanced Technology. This technology allowed for Warships to be created, extended range lasers, specialty vehicles and mechs such as Land Air-Mechs.
  • Experimental Technology - This is highly technology, high expensive and rare. While normally cutting edge, not completely perfected. Earlier technology such as Primitive is also classified as experimental due to them the beginnings of technology was primitive and not fully perfected (Standard Inner Sphere). Advanced stealth equiupment which does not take much room in unit it's equipped in is another example such experimental technologies. In some cases these technologies are only briefly available and then extinct to be never be duplicated again.
Terra Alliance 
The Terran Alliance was 1st interstellar nation formed by Human kind. Center on Terra, the democracy lead nation would usher age discovery with invention of the K-F Jump Drive, creating countless worlds across space. However, as humans colonized space, old political unrest continued on Terra, created divisions among it's political standings, eventually leading to isolationist taking over the leadership of the Alliance and cutting off most it's colonies encircling Terra. As Terra turned on itself ending in a Civil War, it's own military would turn it's guns against the unstable democracy in a coupe lead by Admiral James McKenna. This coupe would form a new nation with limited elections called the Terra Hegemony.
Terra 
This is name used for Earth in the BattleTech universe. It is center of all human culture and once the seat of power for Terran Hegemony, later the Star League, ComStar, and Republic of the Sphere. For most of it's existence, it has been the mostly the most technology world in human space. In later eras, Terra would be again the capital of the Republic of the Sphere and ilClan's version of the Star League. Only casually the name "Earth" has appear in canon which directly refers to the planet itself.

Triple Strength Myomer (Technology) 
This is special version of the metallic-like material used create artificial muscles for various applications. Better Known as TSM, this variant of myomer when heated to correct temperature, will triple the strength of Mech using it for as long as it's at specified temperature. Sole found on use BattleMechs, however a commercial version of this myomer is used but not for combat applications does not have same power as the TSM.

A obscure design concept, Tripods can be any weight class. Standard weights that uses Tripod style, require a Pilot & a gunner to use, while normal 'Mechs only need one MechWarrior to do both. Larger Superheavy 'Mechs have three person crew (Pilot, Engineer/Commander, Gunner). This additional crew allows for a Tripod to do more than one person 'Mech. the three legged design allows it to tranverse terrian quicker than normal machines.

They are type of Mine which detonates when specified weight class of BattleMech steps on it. The weapon effectiveness is limited to weight class it set to trigger. If should be close to the weight class it has change of detonating. Infantry or weights far exceeding the specific weight class its set to explode will cause it not to activate at all.

Usually a finger print is the only action needed to unlock the device's message. It is one few things which are considered to be Lostech that survived the Succession Wars. Usually these messages cost considerable amount of money to send due to the security they provide, which was handled by ComStar. These messages during the Succession Wars and until the end of the Dark Age Era were unable to be read, including by handlers.
Void Signature System 
This is a Experimental Technology level of Stealth system developed by Word of Blake. The 'Mechs fitted with this system are rendered invisible on most sensors. It's stealth system requires use of ECM suite, and slow to no movement to void detection. It is based on Star League's Chameleon Light Polarization Shield and the Null Signature Systems. The technology barely survived the Jihad Era, exclusively belonging to Republic of the Sphere until its fall.[83]
VTOL 
This is type of Combat Vehicle which is basically a type Helicopter, however vertical Launch able can Aircraft be also designated under this type of designation.

Warbook (Software)
This is computer software used to identify combat units that sensors detect. Based on information sensors pick up from magnetic (judging weight detected by movement), visual, and other associated information. The program gives percentage from 0 to 100% on the probability of the identity of what it detecting. New or units never programmed into the Warbook would cause it guess what it is based on data it knows. Essentially, classic example was the appearance of the Clans in 3049 at beginning of the Clan Invasion where the TimberWolf, a Clan heavy OmniMech. The Warbook used existing information and pieced together / assigned its own id. Given the Timberwolf's appearance similar to arms of a Marauder and body of an older Catapult Missile Support Mech. The Warbook noted as similarity assigned name "Mad" "Cat", where Timber Wolf gain it's more famous name, as fusion both Mech's names.

The Wolf Empire runs not to dissimilar to the Rasalhague Dominion, where they co-govern the worlds under Clan Wolf's paws. It's leadership, would be solid by raise of the Alaric Wolf turn Alaric Ward-Steiner, trueborn genechild of Katherine Steiner-Davion. The Empire, continues to push into the center of the Inner Sphere with ambitions of taking Terra. They would reach Terra by 3150 and engage Jade Falcons and the remaining Republic of Sphere armed forces for control of Humanity & the original Star League homeworld.
Word of Blake 
This is religious political organization first formed within the ranks of ComStar, the maintainers of the Inner Sphere's interstellar communication.

They're military would become the Word of Blake Militia, from many of the ComGuard defectors after the split. It would eventually retake Terra for itself, and lead charge reform the Star League at the cost massive war when the quasi 2nd Star League collapsed in 3067. Ultimately leading to it's demise in 3081 and it's members hunted down by the Inner Sphere and Clans a like.
Word of Blake Protectorate 
This was a short-lived nation residing in the heard of what once was called the Chaos March, the very center of the Inner Sphere. From Terra, the Word of Blake began in 3066 to expand the protectorate through initially treaties with neighboring planets and eventually through coups engineered to cause the planet to fall into the Word of Blake's control. With fall of the Second Star League, which enraged the political powers of the Word of Blake, military forces struck most of the Clan Occupation Zones and Inner Sphere Nations capitals. This allowed for the Protectorate to enlarge taking worlds belonging to Federated Suns, Lyran Alliance, Draconis Combine, Free Worlds League, and the Capellan Confederation. Not unlike the ancient Terran Hegemony, these worlds were cemented by native troops of each world forming Protectorate Militia backing up frontline Word of Blake Militias and their recently revealed elite regiments belonging to the Shadow Divisions of the Manei Domini. The Protectorate would last until a Coalition multi-national forces was gathered together formed large military task force liberate worlds of the Protectorate starting in 3076-3078. By 3079, the WoB Protectorate would end up being occupied by this Coalition forces. It was governed under the name "Terran Protectorate" briefly until Coalition leadership convinced it's international and Clan partners the benefits of having a neutral but strong nation holding the Center of the Inner Sphere from further aggression. Thus transforming the former Protectorate into the Republic of the Sphere.
