Rifles on 24

Assault rifle is a term describing a type of automatic rifle generally defined as a selective fire rifle or carbine, chambering intermediate-powered ammunition. They are categorized between the larger and heavier light machine gun, which is intended more for sustained automatic fire in a support role, and the smaller submachine gun, which fires 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 rifles ('battle rifles') such as the regular M16 and AK-47's. These rifles are often used by CTU, terrorists, U.S. Military, and Law Enforcement S.W.A.T. teams.
