Category:Machine guns (Earth-8573)

A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in rapid succession from an ammunition belt or magazine, typically at a rate of 300 rounds per minute or higher. Not all fully automatic firearms are machine guns. Submachine guns, rifles, assault rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire.
