WW2 Weapon can be summarized as two different weapons used during World War II: the STEN, a British submachine gun, and the BRENGUN, a German anti-aircraft gun. The STEN was a lightweight, low-cost submachine gun that was designed to be easy to manufacture and use. It was used by British forces throughout the war and was also adopted by other Allied forces. The BRENGUN was a German anti-aircraft gun that was used to defend against Allied air raids. It was a powerful weapon that could fire up to 800 rounds per minute. Both of these weapons played an important role in the outcome of World War II.
