The Ranger, is fast Heavy OmniMech built 3132 by the Springfield Arsenal in the Royal Federation of Arcadia to meet the their armed force seeking faster 'Mech design.

This unique design was created by Big Steve for his fan story Emergence - The Concert of the Sphere in the Concertverse AU.

  • Wiki Note: This is alternate Universe, however due to limitations of BattleTech mech design programs, items on this Mech will be listed with (CL) as they are equal to Clan Technology. Additionally, this design also uses Experimental Technology, which includes its weapons.


A post-4th Succession War update to the RNG-2, the RNG-3 Ranger is Loric's answer to the need for a fast heavy OmniMech for the AFRF's armored cavalry units.

Battle History[]

During the 3139 fight on Freedom between the 1st Launum Armored Cavalry and the 2nd Sword of Light, the RNG-3 performed admirably in enabling the outmatched Launumeños to stymie and delay the Combine 'Mechs in their destructive rampages through Freedom's countryside. Their speed and the use of jump jets on many configurations provided many opportunities for tactical ambushes or quick responses that thwarted the hunt for Musashi Honda's surviving guerrillas and ensured the 2nd Sword of Light's failure in the campaign.


The Ranger is primarily found in the cavalry-orientated regiments of the AFRF, particularly the Striker regiments and the Royal Cuirassiers. The Kell Hounds and Ransom's Raiders have both shown a certain enthusiasm for the design in their cavalry formations. Loric's main manufacturing center at Hagerstown has been quite active to ensure a regular production rate.

Armament and Equipment[]

With a top speed of over 96 kph, the Ranger is as fast as cavalry "Mechs with lower weight and can even keep pace with light-weight hunter-killer 'Mechs. Since the size of the 360-rated iXL engine proved prohibitive on providing flexible pod space for the design, Springfield Arsenal contracted RussTech for its improved XL gyros as well as employing Terran-quality endo-steel and ferro-fibrous armor. While this removed room for any additional equipment in the core of the machine, it brought the weight down to allow twenty-five tons of pod space, giving the Ranger surprising flexibility for a sixty ton 'Mech with a sixteen and a half ton engine which has 10 Double Heat Sinks.

The "Prime" Configuration/Variant that is Medium Range / Close Range combatant, able take role of the Striker. It's primary weapon (main gun) is it's Class 10 LB-X Autocannon, the right arm mounted weapons draws ammunition from two ammunition bins to allow switch between solid & cluster rounds.

A Streak six-tube Short Range Missile Launcher is mounted in the right torso with a single ton of ammunition mounted in same location. Three additional Heat Sinks are fitted to help manage the configuration heat.

Ammunition: The Prime carries 2 tons of LB-X 10 reloads in right arm. It's Streak SRM ammunition is also stored in the right Torso. CASE is integrated with the chassis (like Clan Mechs)
