The main battle tank[2] is a vehicle used by the United States Armed Forces before the Great War.


A large, heavy duty conventional main battle tanks employed by the United States military. The main battle tank is a behemoth that employs a pair of tracked chassis using leaf spring suspension, with a single turret mounted on the top. Its key advantage is firepower: the main battle tank is equipped with a pair of large-caliber 140mm[1] cannons using conventional ammunition.

Altogether, the tank weighed over sixty tons, making it unusable in marshlands and other soft terrains, despite the reliability that allowed for a single soldier to hotwire them and restore them to working order.[3] The armor of the heavy tank unusually uses riveted steel which actually increases spalling in the cabin from hits. It has no visible secondary armament. The powerplant is an equally heavy-duty nuclear engine, with it back pods allowing for the exposure of heat sinks for quick air cooling while stationary.[4]

  • The tank near relay tower 0BB-915 has become stuck in rough terrain, as evidenced by a handful of skeletal soldiers with shovels. A nearby note indicates that the tank was taken for a joyride by a group of drunken soldiers immediately prior to the Great War.
  • A depiction of the tank appears in the comic strip in the Cold Steel boardgame from the Fallout 76 update Locked & Loaded.


The tank appears in Fallout 4 and Fallout 76.

Behind the scenes[]

The heavy tank was modeled by Tor Frick[5] and implemented by Lucas Hardi.[6] The tank itself is modeled after the M46 Patton tank, which was used by the U.S. Army during the early years of the Korean War.[4]

  4. 4.0 4.1 Modiphius vehicle description
    "This battlefield behemoth is an example of one of the US Army’s pre-war main battle tanks and one of the most powerful vehicles to ever rumble through the wasteland. Powered by a nuclear engine, its single turret design boasts a twin pair of heavy duty 140mm main cannons which it can use to demolish all but the most formidable of assailants in a single salvo. Weighing in at a monster 60 tons, its mass makes it unsuitable for use in soft terrain, but otherwise it’s a steel beast which dominates conventional battlefields. Modelled on the M46 Patton tank last used by the US Army in the conflicts of the mid to late twentieth century, several abandoned examples can be found scattered across the Wasteland and if you’re fortunate to find a working model it can be hotwired and restored to full capacity with a minimum of fuss. Woe betide your foes, if you succeed and one of these leviathans ever becomes fully operational again."
