The Maschinengewehr 34, or MG 34, was a German machine gun that was first produced and accepted for service in 1934, and first issued to units in 1935. It was an air-cooled machine gun firing 7.92 mm Mauser rounds and had similar performance to other medium machine guns.
However, it was also designed to perform both as a light squad machine gun and also in heavier roles, in an early example of a general-purpose machine gun. In the light role, it was intended to be equipped with a bipod and 75-round drum. In the heavier role it was mounted on a larger tripod and was belt-fed. In practice the infantry usually just belt-fed the bipod version, resulting in it functioning as a classic medium support weapon.
It was designed primarily by Heinrich Vollmer from the Mauser Werke, based on the recently introduced Rheinmetall-designed Solothurn 1930 (MG30) that was starting to enter service in Switzerland. The principal changes were to move the feed mechanism to a more convenient location on the left of the breech, and the addition of a shroud around the barrel. Changes to the operating mechanism improved the rate of fire to between 800 and 900 RPM.
The new gun was accepted for service almost immediately and was generally liked by the troops. It was used to great effect by German soldiers assisting the fascists in the Spanish Civil War. At the time it was introduced it had a number of advanced features and the GPMG concept that it aspired to was an influential one. However the MG 34 was also expensive, both in terms of construction and the raw materials needed (49 kg of steel) and it was unable to be built in the sorts of numbers required for the ever expanding German army. It also proved to be rather temperamental, jamming easily when dirty.
In the light machine gun role it was used with a bipod and weighed only 12.1 kg. In the medium machine gun role it could be mounted on one of two tripods, a smaller one weighing 6.75 kg, the larger 23.6 kg. The larger tripod, the MG-34 Laffette, included a number of features such as a scope and special sighting equipment for indirect fire. The legs could be extended to allow it to be used in the anti-aircraft role (and many were), and when lowered it could be placed to allow the gun to be fired "remotely" while it swept an arc in front of the mounting with fire, or aimed through a periscope attached to the tripod.
After WWII some MG42s were in turn rechambered for the new (at the time) 7.62 x 51 mm NATO cartridge and classified as MG2 while a slight redesign was called the MG1. The seventh and final design iteration of the MG1 was called the MG3 and it currently (as of 2006) still in service around the world.
