During World War II, the MG 34 was supplemented by a new GPMG, the MG 42, although it remained in combat use.[6][7][8] The MG 42 was more efficient and cheaper to manufacture, and more robust, as well as having an extremely high cyclic rate of fire of 1,200 to 1,500 rounds per minute.[6][7][8] One of the Einheits Maschinengewehr GPMG roles was to provide low level anti-aircraft coverage. A high cyclic rate of fire is advantageous for use against targets typically exposed to fire for a limited time span, like aircraft or targets minimizing their exposure by quickly moving from cover to cover. It was nicknamed "Hitler's buzzsaw" by Allied troops, and alongside the MG 34 it inflicted heavy casualties on Allied soldiers on all European and North African fronts of World War II.[6][8][9] Following the war the victorious Allied nations took an interest in the MG 34 and MG 42, influencing many post-war general-purpose machine guns, many still in use today. They lent design elements to the Belgian FN MAG and the American M60, while spawning the Zastava M53, Swiss M51, and Austrian MG 74. The MG 42's qualities of firepower and usability meant that it became the foundation of an entire series of postwar machine guns, including the MG 1 and MG 3; the latter, as of 2023[update], is still in production.[6][7][8][10]
