An assault rifle is a selective fire rifle or carbine firing ammunition with muzzle energies intermeiate between those typical of pistol and battle rifle ammunition. Assault rifles are categorized between light machine guns, intended more for sustained automatic fire in a support role, and submachine guns, which fire a handgun cartridge rather than a rifle cartridge. Assault rifles are the standard small arms in most modern armies, having largely replaced or supplemented larger, more powerful battle rifles, such as the World War II-era M1 Garand and Tokarev SVT. Examples of assault rifles include the AK-47 and the M16 rifle. Semi-automatic rifles, including commercial versions of the AR-15, and "automatic" rifles limited to firing single shots, even though incorrectly classified in the United States as assault rifles by the now defunct 1994 Assault Weapons Ban, are not assault rifles as they are not selective fire. Belt-fed weapons or rifles with very limited capacity fixed magazines are also generally not considered assault rifles.
