Picture of the Sten in Real Life
The Sten was used by the Brittish in the World Wars, it was a great weapon because it was quick and cheap to produce. An advantage of the Sten was that you could use captured German ammunition.
 Call of Duty
In Call of Duty 3 this gun was only used in a few missions but when you did use it there was no problem with it. One of the best things about the Sten was the side-mounted magazine which allowed a quick reload.
