|Type 100 submachine gun|
The Type 100 submachine gun is a Japanese submachine gun.
The Type 100 submachine gun, designed and built by the Nambu Arms Manufacturing Company, was the only submachine gun produced by Japan in any quantity. It was first delivered in 1942 and used during World War II in several variants. Unusually for a submachine gun, a bayonet can be attached to the barrel, but this feature was seldom used in combat. Early models of the Type 100 were plagued by frequent jamming caused by the feeding mechanism. This was solved with later, simplified models, which also had a higher rate of fire. Overall, firepower of the weapon was inferior compared with Allied submachine guns, because it was chambered for the small 8x22mm Nambu pistol cartridge, whereas its counterparts used more powerful military pistol cartridges such as 9mm parabellum and .45 ACP.
The Type 100 is the primary weapon for the Japanese medic class in Battlegroup42.
