Designation: Caterpillar CBL-10 Triton Light Combat Battloid

I. Dimensions:

  • Total Height: 6.2 m
  • Total Depth: 2.6 m
  • Total Breadth: 3.0 m
  • Weight: 13.2 metric tons

II. Type:

  • Design: Caterpillar/Vickers-Chrysler Robotech Systems Inc.
  • Builder: Caterpillar, Fábrica Argentina de Aviones
  • One-man Light Combat Battloid

III. Service Life:

  • Used by the UEDF Tactical Corps Marsh Division from 2015 until 2031. The Triton was also used by the Land Forces of the Merchant Republic from 2020 until 2031, and by the Soviet Union as the GBR-25 (UEDF reporting name Roundhouse) from 2022 until 2031.

IV. Propulsion:

  • Powerplant: SCE-2P Miniaturized Protoculture-cell energizer
  • Fuel Capacity: 6 Standard Canisters of Protoculture.
  • 4 x BRT-10 reaction thrusters mounted in the ankles, each capable of producing a maximum rated output of 15 kN.

V. Performance:

  • Running speed: 88 kph
  • Max jumping performance: Typically 30 meters high out to a distance of 75 meters.
  • Protoculture supply: 225 hours operational use.

VI. Electronics:

Sensor Systems:

  • Westinghouse TPG-144 X-band pulse-doppler phased array radar with battlefield surveillance mode.
  • Phillips AllView II multi-band digital spherical camera system, for medium range all attitude infra-red imaging, optical and ultra-violet band detection and tracking in Battloid mode
  • Thomson LT-8 multi-frequency laser ranger and designator.

Tactical Electronic Warfare System:

  • Selenia GroundWarrior active/passive sensor jammers.

VII. Armament:


  • 1 x General Electric E-18 ion cannon mounted in the forehead. Capable of firing 400 kJ pulses at a rate of 90 per minute, primarily designed to intercept missiles.

(CBL-10-Mk. I)

  • 2 x Vickers 40mm Grenade launchers mounted on the forearms. The launchers can fire up to 50 grenades each before reloading is necessary. Typical riot duty includes a mixture of tear gas, smoke, and fire suppressant rounds, while combat duty includes HE, HEAT and Anti-Personnel rounds.

(CBL-10-Mk. II)

  • 2 x CCWS-001 retractable close combat weapons system, consisting of a 0.9 meter long tungsten/ceramic vibro-blade mounted in each arm in place of the Mark I’s grenade launchers.

Optional hand-held gun pods:

  • or 1 x Mauser EU-10 Laser Gun Pod. This gun pod fired energy pulses of up to 10 MJ per blast. This gun pod could fire up to 150 times/minute due to the large capacitors mounted on either side of the pod. This was the most common gunpod assigned to these Battloids due to its decent penetration capabilities and high rate of fire. The weapon incorporated a carrying handle to assist in transportation and could be attached to an arm in a carrying position.
  • or 1 x Mauser EU-11 28mm Laser Gun Pod. This gun pod fired energy pulses of up to 12.5 MJ per blast. This gun pod could fire up to 110 times/minute. This was the gun pod issued to the VHT-2 Hovertank due to its smaller size and higher penetration capabilities.
  • or 1 x General Electric EU-12 pulse laser pod, firing 12 MJ pulses at 130 pulses per second. Specially developed for the SC ground Battloids, this cannon used pulse technology to offset the beam attenuation caused by the lower layers of the atmosphere in which it was used. This pod was utilized in cases where more impact than penetration was required, and was introduced around 2031, although primarily with the combat Battloids first.

VIII. Armor:

The armor on the Triton is a new development in low-mass composite-materials Chobham plating that became the standard for all Terran mecha after its application to the VQ-6A Vandal. Aside from the respectable protection provided against projectiles, missiles, and other kinetic weapons, this armor is also resistant to plasma globes (annihilation discs), lasers, and to a lesser extent, particle guns, owing to the fact that the armor can flake off and evaporate in layers under fire from such high-energy weapons, taking much of the weapon’s energy and converting it into the latent heat of sublimation in the armor. The armor stops all small arms, heavy infantry weapons fire, and light mecha-mounted weaponry, provides fair to good resistance to medium mecha-mounted weaponry, such as the Valkyrie’s 55mm APFSDS round, and provides poor resistance to heavy mecha-mounted weaponry, such as the VHT-1’s 105mm shell.

The Triton provides full protection from nuclear, biological, and chemical hazards, using a fully-sealed cockpit module activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The cockpit module is also armored and gives the Triton the option of operating off-planet on the moon or elsewhere in the system. The internal consumables supplies can provide atmosphere purification for one week maximum on Earth and 48 hours in a hostile environment such as the moon or Mars.

IX. Development:

The UEDF Surface Command decided that the large vintage Destroids were too conspicuous and vulnerable to standoff missile attacks to be fully effective. Also, in urban combat, the huge robots could easily lose small vehicles in back streets that were too small to accommodate the large Destroids. As such, they desired to create a smaller and more agile mecha that could better adapt to a variety of operating environments. From this desire, the Battloid concept evolved: a smaller, more agile, multi-purpose robot. To decrease the size and provide operational flexibility, the primary weapons shifted to an assortment of gunpods instead of the slow to reload integral weapons. The Triton retained an integral laser weapon so that the power of the mecha’s protoculture energizer could be tapped to supply the demand of the anti-missile air defense laser, as well as a pair of grenade launchers for self-defense and secondary missions. It was also beneficial that the smaller Battloids were much simpler and cheaper to manufacture allowing the depleted UEDF armies to rapidly rebuild a cohesive fighting force after being depleted by the departure of the Pioneer mission and their appropriation of most of Earth’s mecha forces.

The CBL-10 Triton was designed by Caterpillar and Vickers-Chrysler Robotech Systems Inc. in the late teens. The design intent was to build a light weight Battloid for use in marshy and jungle environments, such as the Amazon Basin, during the Malcontent Uprisings. Unlike the CBL-8 Dryad, the Triton was developed from conception as a light combat robot. The CBL-10 Triton was also designed from the beginning to be capable of air borne operations, with four BRT-10 reaction thrusters mounted in the ankles to arrest its fall when dropped by parachute. These thrusters also improved the Tritons leaping performance, though they did not give it true jump capability like the CBH-4 Salamander. The Triton was also equipped with exceptionally strong servo motors, as Caterpillar was planning to sell it on the civilian market. (This never came to fruition, as Caterpillar was later acquired by Haneda Heavy Industries in 2016.)

EBSIS GBR-25 Dzhaggernaut (Juggernaut) Roundhouse Main Battle Robot 1The Triton served primarily with the Tactical Corps Airborne Divisions, as well the Marsh Division, where its light weight made particularly adept at moving through swamps and river estuaries. In addition to being built by Caterpillar, the Triton was also manufactured under license by Fábrica Argentina de Aviones in their factory in Montevideo in el
Vencedor. When el Vencedor seceded from the United Earth Government to form the Merchant Republic in 2020, the new government nationalized the Fábrica Argentina de Aviones facility and continued to produce the Triton for its own forces. The Merchant Republic found itself in the Eastern Block of Soviet Independent States after its secession, and sold a great many of its locally produced Tritons to the Soviet Union. The Soviets eventually began building the Triton under license at the Leningrad Kirov Plant (LKZ) as the GBR-25 Dzhaggernaut (Juggernaut, UEDF reporting name: Roundhouse) Main Battle Robot.

Many Tritons survived the Second Robotech War and, along with their Soviet analogues, saw widespread use in the early years of the Invid Occupation.
