The Parabellum MG 14 was a 7.92 mm caliber World War I machine gun built by Deutsche Waffen und Munitionsfabriken.
Like the earlier Vickers machine gun, it used a toggle action that broke upwards rather than downwards, the opposite way to the MG 08, making for a much more compact receiver.
The MG 08's belt-style ammunition feed was enclosed in a drum, the recoil casing was lightened and the cooling jacket was modified for air- instead of water-cooling.
An MG 14 was used in the early development of the German version of the gun synchroniser by Anthony Fokker.
However, the limited supplies of the weapon were more urgently needed for observers in reconnaissance aircraft and defensive gunners aboard Zeppelins and heavier-than-air bombers and it was reserved for flexible mounts where its combination of light weight and high rate of fire were most useful.
