M310 smooth-bore high-velocity cannon

The 120mm high-velocity gun is an anti-tank weapon that fires High-Explosive Anti-Tank (HEAT) shells at extremely high velocity. The kinetic force adds to the explosive firepower of the shell. Two such cannons served as the main armament of Sergeant John Forge's self-created Grizzly tanks. It is more powerful than the M512 90mm cannon equipped on the standard M808B Main Battle Tank.
