A British submachine gun used during World War II, or its variants.
Acronym from 'Sten' combining the designers' names (Shepherd and Turpin) and 'EN' for Enfield factory. Created 1941, it became one of WWII's most famous weapons.
The Sten gun was so simple to manufacture that the British made over 4 million during WWII, and so easy to build that other countries created illegal copies—simplicity was its superpower.
