If anone is wondering what in the fresh hell is going on here, et me help you...
The Sten Mk.ΙΙ was a nightmare... Firing in full auto -occasionally- when placed on single ( and vice-versa ), discharging accidentaly ( even when placed on the ground ) and , of course, the ever popular problem : jamming in an inopportune moment...
The only redeeming qualities of this weapon were the production cost, the slim profile, the ease of reassembly/disassembly and the size, making a well-maintained Sten a decent weapon to use. It was also a guerilla and partisan favourite.
tl,dr: that is a poor android trying to run away from her own, malfunctioning weapon...
