The M1 carbine is a lightweight, easy-to-use, semi-automatic carbine that became the standard firearm for the U.S. military during WW2, the Korean War and the Vietnam War. It was used widely by the U.S. military and foreign forces, paramilitary and police units.
The first M1carbines were delivered in mid-1942, with initial priority given to troops in the European Theatre of Operations (ETO).
The M1 carbine with its reduced-power .30 cartridge was not intended to serve as a primary weapon for combat infantrymen. However, it soon became a popular with infantry officers, U.S. paratroopers, NCOs, ammunition bearers and the Military Police.
