MP-18 SMG

The MP 18 was a World War I-era submachine gun designed and manufactured by Germany. Introduced into service in 1918 by the German Army during World War I as the primary weapon of the Sturmtruppen, assault groups specialized in trench combat, it was arguably the first such weapon used in combat. The MP 18 remained in limited service with the German armed forces during the Second World War, specifically with the Sicherheitsdienst, later eastern foreign divisions of the Waffen SS and also with Kriegsmarine coastal artillery units.
