M310 smooth-bore high-velocity cannon

The M310 smooth-bore high-velocity cannons, or simply M310 guns, are two 120mm guns mounted on the M850 "Grizzly" Main Battle Tank.

Overview
The M310 guns fire high-explosive anti-tank (HEAT) shells at very high velocity; the kinetic force adds to the explosive firepower of the shell. The weapon can be loaded with S1 canister shells, which produce a large, high-volume blast of explosive fragments, greatly increasing the weapon's lethality against infantry.
