The M2 Machine Gun or Browning .50 Caliber Machine Gun is a heavy machine gun designed toward the end of World War I by John Browning.
 Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 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").
 It has been referred to as "Ma Deuce", in reference to its M2 nomenclature.
 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 low-flying aircraft.
 The M2 has been produced longer than any other machine gun.
The Type 92 Heavy Machine Gun (九二式重機関銃 , Kyūni-shiki jū-kikanjū ) entered service in 1932 and was the standard Japanese heavy machine gun used during World War II.
 It was used extensively by the Imperial Japanese Army and Collaborationist Chinese forces.
 Captured weapons were also used extensively by Chinese National Revolutionary Army troops against the Japanese during World War II, and the Korean People's Army against the United Nations forces during the Korean War.
 The Type 92 refers to the Japanese Imperial year 2592 – 1932 in the Gregorian calendar – in which the gun entered service.
 Designed by Kijiro Nambu and built by Hino Motors and Hitachi, total production was about 45,000 guns.
The Type 3 Heavy Machine Gun (三年式重機関銃 , San-nen-shiki juu-kikanjuu ) , also known as the Taishō 14 Machine Gun, was a Japanese air-cooled heavy machine gun.
The QJZ-89, also known as the Type 89 heavy machine gun is a heavy machine gun designed in the People's Republic of China.

 The weapon is both gas (three settings) and recoil operated.
 The ammunition belt is the standard DShK metal non-disintegrating link.
The Flieger MG 29 (also called the Flab MG or FLab MG 29/38) was a Swiss light machine gun developed in the 1920s and produced until shortly before the dawn of the Second World War.
 It was mounted on aircraft and was later used as an anti-aircraft gun.
 However, it was too heavy to be used as am infantry support weapon.
 It employed a closed bolt system.
 Some guns had the ability to bolt a large box onto the bottom of the machine gun to hold the ammunition belt.
 Two versions of the gun existed, the "normal" version and a second version which bolted two guns together and made them to fire from the same trigger, known as the "Doppel-MG" (double machine gun).
 After the second world war, better anti aircraft systems and aircraft weapons were available to Switzerland and the infantry support role was filled by the MG 51.
 The higher rate of fire, but much heavier MG 29 was finally mounted on the first prototype of the Panzer 58, the precursor to the more famous Panzer 61 tank before being retired.
The DShK 1938 (ДШК, for Дегтярёва-Шпагина Крупнокалиберный, "Degtyaryova-Shpagina Krupnokaliberny", "Degtyaryov-Shpagin Large-Calibre") is a Soviet heavy machine gun firing the 12.7×108mm cartridge.
 The weapon was also used as a heavy infantry machine gun, in which case it was frequently deployed with a two-wheeled mounting and a single-sheet armour-plate shield.
 It took its name from the weapons designers Vasily Degtyaryov, who designed the original weapon, and Georgi Shpagin, who improved the cartridge feed mechanism.
 It is sometimes nicknamed "Dashka" (familiar form of female name Daria) in Russian-speaking countries, from the abbreviation.
A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute.
 Not all fully automatic firearms are machine guns.
 Submachine guns, rifles, assault rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire.
 As a class of military rapid-fire guns, machine guns are fully automatic weapons designed to be used as support weapons and generally used when attached to a mount or fired from the ground on a bipod or tripod.
 Many (but not all) machine guns also use belt feeding and open bolt operation, features not normally found on rifles.
