Sten MkII

The STEN (or Sten gun) was a family of British submachine guns chambered in 9×19mm and used extensively by British and Commonwealth forces throughout World War II and the Korean War. STEN is an acronym, from the names of the weapon's chief designers, Major Reginald V. Shepherd and Harold Turpin, and EN for Enfield.

They were notable for having a simple design and very low production cost making them effective insurgency weapons for resistance groups. The Mark II was the most common variant, with two million units produced. ...
