M1 Carbine
From Gunpedia
The M1 Carbine is a .30 caliber Carbine that has been used since WW2 and is still a popular weapon amongst todays Law Enforcement/Security Forces around the world, along with civilian use, it is chambered in .30 Carbine. Due to it being a carbine, it has a shorter barrel, and length, compared to rifles used in World War II (such as the M1 Garand), thus lowering power and range significantly compared to other conventional rifles. However the M1 Carbine was used much during the war. It has been favored for its mild recoil, by soldiers and collectors alike.
[edit] Paratroopers
The M1 was used for paratroopers during WWII, mainly the folding stock was used for the boys. The military wanted a light gun that could pack a punch to help paratroopers get into a safe place without having to lug around more weight when they hit the dirt (paratroopers were fitted with everything in case of an emergency).
