What it is

A portable automatic weapon with a short barrel firing a pistol cartridge (9 mm Parabellum) with a drum magazine, for trench fighting. It was issued to German assault troops in 1918 and gave the submachine gun its name.

The Italian Villar-Perosa (1915) is sometimes considered the first submachine gun, but it was a twin-barrelled support weapon; the Thompson (1918) and MP 18 compete as the first in service.

What it led to

  • the Thompson, Sten, PPSh-41 and MP 40
