The Sten Mk2 is a British weapon designed for recon crews, trading out range/damage for reliability, lower weight, and a larger clip size. It is a fairly good all-round weapon, requiring no particular traits.
The Sten Mk2 was a weapon born out of necessity during WW2. The British, unable to import enough Thompson submachine guns were unable to field a light automatic weapon in large numbers. As a result, the War Ministry commissioned a project to produce a domestic product. The Sten was the outcome and reflects an austere design principle. Manufactured from stamped metal and uncomplicated, this weapon was produced en-masse and went on to arm many troops (conventional and unconventional) throughout WW2. Its appearance was quite strange and earned many monikers such as the "Stench Gun" or "Plumber's Nightmare". Despite some manufacturing inconsistencies, a well made and maintained Sten was an effective weapon (and was documented to be in limited use by US forces). Its British donation and adoption by Israeli forces eventually resulted in the development of the Uzi SMG.
