M242 Bushmaster autocannon on an M2 Bradley.

An autocannon is a projectile weapon with a larger bore size than a machine gun, and a faster rate of fire than regular cannon used by artillery units. The term developed from WWII guns used in aircraft, where the distinction was that the shells were explosive. After the war similar guns were used with non-explosive rounds in the anti-tank role, and the name autocannon started to become popular. Autocannon today are typically distinguished by their incorporation of some method of automated loading and firing. The M242 Bushmaster Cannon on the M2 Bradley. ...
