The legendary British, World War II STEN submachine gun is featured in this concise, illustrated book. Famous for its use by British elite forces, as well as the French underground during WWII, variants of the STEN were manufactured and used by many countries during the war and up through the 1970s. Beginning with its initial design and construction, the Mk.I and Mk.I*, Mk.II, Mk.III, and Mk.5 versions are presented in detail, including up-close images of manufacturer's markings.
