About Autocannons

An autocannon or automatic cannon is a rapid-fire projectile weapon that fires an explosive shell, as opposed to the bullet fired by a machine gun. Autocannons often have a larger caliber than a machine gun (i.e., 20 mm or greater). Usually, autocannons are smaller than a field gun or other artillery, and are mechanically loaded for a faster rate of fire.
