The standard infantry weapons in most modern armies, assault rifles are automatic rifles that use intermediate cartridges and detachable magazines. Assault rifles are categorized in between light machine guns, which are intended more for sustained automatic fire in a light support role, and submachine guns, which fire a pistol cartridge rather than a rifle cartridge. Most famous and widely used examples of assault rifles include the Kalashnikov family, the M16 rifle, Enfield SA80, Heckler & Koch G36, FN F2000, and the Steyr AUG.
