The M2 Machine Gun, or Browning .50 Caliber Machine Gun is a heavy machine gun designed just after World War I by John Browning. It is nicknamed Ma Deuce by US troops or simply called fifty caliber machine gun. The design has had many specific designations- the official designation for the infantry type is Browning Machine Gun, Heavy Barrel, Cal. .50, M2, HB, Flexible. The Browning .50 machine gun was used extensively as a vehicle weapon and for aircraft armament by the United States from the 1920s to the present day. It was heavily used during World War II, Korean War, the Vietnam Conflict, as well as during operations in Iraq in the 1990s and 2000s. It is the primary heavy machine gun of NATO countries, and has been used by many other countries. It is still in use today. It was very similar in design to the smaller Browning Model 1919 machine gun .30-06 Springfield.

Relationships      
Parents 重機槍 A heavy machine gun refers to either a larger-caliber, high-power machine gun or one of the smaller, medium-caliber (rifle caliber) machine guns meant for prolonged firing from heavy mounts, less mobile, or static positions (or some combination of the two). The latter meaning is generally thought of as an older meaning, and the former as a modern one, but both weapon types have histories extending back to the 1800s. Furthermore, heavier smaller-caliber weapons continue to be used up to the present. A classic example of a rifle-caliber heavy machine gun would be a water-cooled Maxim machine gun that was belt fed, had a water jacket, was crew served, and mounted on tripod or wheeled mount. Other types used linkable strips (such as the Hotchkiss) or large magazines. A common example of a heavy-caliber machine gun would be the Browning M2 .50-caliber machine gun. Firearms with calibers larger than 13 to 15 mm are generally thought of as autocannons instead of heavy machine guns. (from Wikipedia)
