The M2 Machine Gun or Browning .50 Caliber Machine Gun is a heavy machine gun designed towards the end of World War I by John Browning. It is very similar in design to Browning's earlier M1919 Browning machine gun, which was chambered for the .3006 cartridge. The M2 uses the much larger and much more powerful .50 BMG cartridge, which was developed alongside and takes its name from the gun itself (BMG standing for Browning Machine Gun). The M2 has been referred to as "Ma Deuce", as a GI phonetic slang or "the fifty" in reference to its caliber. The design has had many specific designations; the official designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications and lowflying aircraft. The M2 machine gun has been in production longer than any other machine gun.
The Browning .50 caliber machine gun has been used extensively as a vehicle weapon and for aircraft armament by the United States from the 1930s to the present. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, and during the Iraq War and War in Afghanistan in the 2000s and 2010s. It is the primary heavy machine gun of NATO countries, and has been used by many other countries. The M2 has been in use longer than any other small arm in U.S. inventory except the .45 ACP M1911 pistol, also designed by John Browning.
The current M2HB is manufactured in the United States by General Dynamics and U.S. Ordnance for use by the United States government, and for U.S. Foreign Allies via FMS sales. FN Herstal has manufactured the M2 machine gun since the 1930s.
