  • Length: 8.2 meters
  • Width: 3.8 meters
  • Height: 4.8 meters
  • Weight: 15.2 metric tons.

II. Type.

  • M-120 HAV: Two crew lightly-armored amphibious 6-wheeled personnel carrier and infantry fighting vehicle, capable of carrying up to 12 foot soldiers with standard gear.
  • MT-1 MLRS: Three crew lightly-armored amphibious 6-wheeled missile launcher system.

III. Service Life

  • M-120 HAV: Replaced the LACV-60 Light Cavalry Vehicle beginning in 2015, and was used extensively by the UEDF ground forces and to a lesser extent by the UEEF Tactical Corps and Marine Corps.
  • M-120A: UEEF protoculture cell-powered electric flywheel engine version to reduce noise and environmental emissions for infiltration operations.
  • MT-1 HAMLRS: Used by the UEDF and UEEF, this rocket artillery piece was adapted from the Fiat M-120 HAV. This variant was introduced in 2020 to provide a rapid deployment rocket/missile battery to supplement the aging MLSAM-8 system.

M-120 HAV

  • The commander’s hatch of the M-120 could mount any of a variety crew serve weapons. Most common was the FN MAG 7.62x51mm NATO general-purpose machine gun, M2 HB Browning .50 Caliber (12.7x99mm NATO) Machine Gun, (unnamed .50 CAL) or Mk 19 40mm automatic grenade launcher.
  • Gun ports for passengers


  • 1 x Missile Launcher system carrying 30 300mm x 4m short range surface-to-surface missiles.
  • or 1 x HD SX-2 Missile system containing 6 x Long range 700mm x 4m Surface-to-Surface/Air missiles capable of targeting vessels at altitudes of up to 30,000m, but the missile will be ballistic for the latter portion of the flight.

MT-1 Hell Peacock 1VIII. Armor.

The armor of the Fiat 6836/6846 Heavy Armored Vehicles is composed of a standard Chobam laminar developed in the late 20th century and improved with the materials science advances made during the Robotech era. This armor was mainly designed to defeat projectiles and other kinetic weapons. The armor stops all small arms, and heavy infantry weapons fire, provides good resistance to light mecha-mounted weaponry, and provides fair resistance to medium mecha-mounted weaponry, such as the Valkyrie’s 55mm APFSDS round.

The 6836/6846 provides full protection from nuclear, biological, and chemical hazards, using an overpressure crew compartment environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies can provide atmosphere for one week maximum.

IX. Development.

The 6836 and 6846 Heavy Armored Vehicle designs were based on FIAT’s 6636 heavy armored vehicle fielded in the 1980’s and in use during the Global Civil War. The 6836 APC provided a weapons mount for a crew serve weapon. The United Earth Defense Forces (UEDF) gave this vehicle the designation M-120. A number of the United Earth Expeditionary Forces (UEEF) vehicles were upgraded to a protoculture engine to boost performance and reduce emissions.

M-120 Armored Infantry Vehicle 1The 6846 was a missile platform variant of the 6836 where the top of the vehicle was redesigned to accommodate the missile system. This provided a relatively agile and quick response missile artillery platform that provided some degree of protection to the crew. The UEEF gave this missile transport the designation MT-1, which was eventually adopted by the UEDF as well.

While many of these vehicles were constructed and put in use around the world, the Robotech Masters’ Bioroids and Invid troops were more than a match for these vehicles and not many survived the wars.
