Bren guns are also known as light machine guns and squad automatic weapons. These weapons were first introduced by Britain in the 1930s and were used extensively in World War II. Today, Bren guns are still used by some military and police forces around the world. Other synonyms for this weapon include automatic rifles, submachine guns, and assault rifles. However, each of these weapons differs slightly in terms of design and functionality. Additionally, Bren guns are often compared to the M1919 Browning machine gun, which was another popular weapon used during World War II. Regardless of the synonym used, Bren guns are highly lethal and effective weapons that have played a key role in shaping military history.
