The light machine gun was an important weapon of World War II. Designed to support infantry, it could be carried and operated by a single soldier. Heavy and medium machine guns, on the other hand, required two or more.
The British light machine gun was the Bren Gun. It was developed in the 1930s and continued to be used by the British Army until 1992. It is most well known for its use in World War II, when it was the main British light machine gun, but it was also used in the Korean War and other conflicts, including the Falklands War of 1982.
The German light machine gun during World War II was the MG-34, considered by many to be the best machine gun in the world at the time. It could be carried very easily by one man and could fire up to 900 rounds a minute. At best the Bren could only fire 520 a minute. The MG-34 was made in huge numbers after 1936, after Hitler decided to ignore the Treaty of Versailles. This was the treaty that ended World War I. The Germans had to promise, among many other things, to restrict the number of weapons and the kind of weapons they could build.
The MG-34 was first used in 1936 by German troops helping the Nationalists in the Spanish Civil War.
