The M8-120 Thunderbolt II is a Tier 9 progression Light Tank under Marat Shishkin's dealership.

History[]

Class: Light Tank (Prototype)
Developed: 1993-2015
Service: N/A
Vehicles Built: 2
Operators: N/A

The M8 (also called "Thunderbolt II") is an upgraded XM8 prototype from the old Armored Gun System program from the 1990s, initially developed to replace the obsolete M551 Sheridan Light Tank. The program was originally terminated in 1997 due to lack of funding and would then stay dormant for more than half a decade. In October 2003, the company that had built the original XM8 unveiled an upgraded prototype called M8 Thunderbolt Enhanced Capability Demonstrator. The biggest change was the gun upgrade. Instead of the older 105mm gun, the Thunderbolt had a 120mm soft-recoil smoothbore gun that could fire standard NATO 120mm APFSDS and HEAT ammunition. Unfortunately, nobody was interested in this vehicle.

In 2006, a second (different) Thunderbolt prototype appeared with a different name (120 Armored Gun System or 120AGS) only to be shelved again and revived another decade later. In 2015, the final iteration of the Thunderbolt appeared as a contender in the recent U.S. Army Mobile Protected Firepower program only to again disappear after not being selected, this time probably for good.

Vehicle Traits[]

  • Stealthy: This vehicle does not lose any camouflage when moving at any speed, which is handy primarily for scouting.
  • Heavy Weapon: This vehicle carries one of the largest weapons around with significantly increased damage per shot.
  • Modern Kinetic Rounds: This vehicle's kinetic (APFSDS) rounds are very effective against ERA kits.
