The MP 18 is a German submachine gun designed and manufactured by Bergmann Waffenfabrik. Introduced into service in 1918 by the German Army during World War I, the MP 18 was intended for use by the Sturmtruppen, assault groups specialized in trench combat, as a short-range offensive weapon that would provide individual soldiers with increased firepower over a pistol.

Although MP 18 production ended after World War I, it was highly influential on subsequent small arms design; it formed the basis of most submachine guns manufactured between 1920 and 1960.^[3]
