The Sten submachine gun - officially the "Carbine, Machine, Sten" - was developed to fulfill the pressing British need for large quantities of cheaply produced weapons after Dunkirk, when German invasion was a very real possibility. Over four million were built during World War II, and the Sten was widely used by airborne troops, tankers, and others who needed a compact weapon with substantial firepower. It proved especially popular with Resistance fighters as it was easy to conceal, deadly at close range, and could fire captured German ammunition - with a design so simple that Resistance fighters were able to produce them in bicycle shops. Featuring vivid first-hand accounts, specially commissioned full-colour artwork and close-up photographs, this is the fascinating story of the mass-produced submachine gun that provided Allied soldiers and Resistance fighters with devastating close-range firepower.
