small arms and light weapons
The International Instrument to Enable States to Identify and Trace, in a Timely and Reliable Manner, Illicit Small Arms and Light Weapon", adopted by the United Nations General Assembly on 8 December 2005, defines small arms and light weapons as:
any man-portable lethal weapon that expels or launches, is designed to expel or launch, or may be readily converted to expel or launch a shot, bullet or projectile by the action of an explosive, excluding antique small arms and light weapons or their replicas. Antique small arms and light weapons and their replicas will be defined in accordance with domestic law. In no case will antique small arms and light weapons include those manufactured after 1899:
(a) “Small arms” are, broadly speaking, weapons designed for individual use. They include, inter alia, revolvers and self-loading pistols, rifles and carbines, sub-machine guns, assault rifles and light machine guns;
(b) “Light weapons” are, broadly speaking, weapons designed for use by two or three persons serving as a crew, although some may be carried and used by a single person. They include, inter alia, general purpose or universal machine guns, medium machine guns, heavy machine guns, rifle grenades, under-barrel grenade launchers and mounted grenade launchers, portable anti-aircraft guns, portable anti-tank guns, recoilless rifles, man portable launchers of anti-tank missile and rocket systems, man portable launchers of anti-aircraft missile systems, and mortars of a calibre of less than 100 millimetres.[2]
