A general-purpose machine gun (GPMG) is an air-cooled, usually belt-fed machine gun that can be adapted flexibly to various tactical roles for light and medium machine guns. A GPMG typically features a quick-change barrel design calibered for various fully powered cartridges such as the 7.62×51mm NATO, 7.62×54mmR, 7.5×54mm French, 7.5×55mm Swiss and 7.92×57mm Mauser, and be configured for mounting to different stabilizing platforms from bipods and tripods to vehicles, aircraft, boats and fortifications, usually as an infantry support weapon or squad automatic weapon.
The T-26 tank was a Soviet light tank used during many conflicts of the Interwar period and in World War II. It was a development of the British Vickers 6-Ton tank and was one of the most successful tank designs of the 1930s until its light armour became vulnerable to newer anti-tank guns. It was produced in greater numbers than any other tank of the period, with more than 11,000 units manufactured giving it the title of the most produced tank during the interwar period. During the 1930s, the USSR developed 53 variants of the T-26, including flame-throwing tanks, combat engineer vehicles, remotely controlled tanks, self-propelled guns, artillery tractors, and armoured carriers. Twenty-three of these were series-produced, others were experimental models.
The MG 34 is a German recoil-operated air-cooled general-purpose machine gun, first tested in 1929, introduced in 1934, and issued to units in 1936. It introduced an entirely new concept in automatic firepower – the Einheitsmaschinengewehr – and is generally considered the world's first general-purpose machine gun (GPMG). Both the MG 34 and MG 42 were erroneously nicknamed "Spandau" by Allied troops, a carryover from the World War I nickname for the MG 08, which was produced at the Spandau Arsenal.
The MG 42 is a German recoil-operated air-cooled general-purpose machine gun used extensively by the Wehrmacht and the Waffen-SS during the second half of World War II. Entering production in 1942, it was intended to supplement and replace the earlier MG 34, which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II.
The Maxim gun is a recoil-operated machine gun invented in 1884 by Hiram Stevens Maxim. It was the first fully automatic machine gun in the world.
The Vickers machine gun or Vickers gun is a water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allied World War I fighter aircraft.
The FN MAG is a Belgian 7.62 mm general-purpose machine gun, designed in the early 1950s at Fabrique Nationale (FN) by Ernest Vervier. It has been used by more than 80 countries and it has been made under licence in several countries, including Argentina, Canada, Egypt, India, and the United Kingdom.
The Degtyaryov machine gun or DP-27/DP-28 is a light machine gun firing the 7.62×54mmR cartridge that was primarily used by the Soviet Union, with service trials starting in 1927, followed by general deployment in 1928.
The PK, is a belt-fed general-purpose machine gun, chambered for the 7.62×54mmR rimmed cartridge. The modernized and most commonly known variant, known as the PKM, features several enhancements over the original PK design.
The DShK 1938 is a Soviet heavy machine gun. The weapon may be vehicle mounted or used on a tripod or wheeled carriage as a heavy infantry machine gun. The DShK's name is derived from its original designer, Vasily Degtyaryov, and Georgi Shpagin, who later improved the cartridge feed mechanism. It is sometimes nicknamed Dushka in Russian-speaking countries, from the abbreviation.
The M1917 Browning machine gun is a heavy machine gun used by the United States armed forces in World War I, World War II, the Korean War, and the Vietnam War; it has also been used by other nations. It was a crew-served, belt-fed, water-cooled machine gun that served alongside the much lighter air-cooled Browning M1919. It was used at the battalion level, and often mounted on vehicles. There were two main iterations: the M1917, which was used in World War I and the M1917A1, which was used thereafter. The M1917, which was used on some aircraft as well as in a ground role, had a cyclic rate of 450 rounds per minute. The M1917A1 had a cyclic rate of 450 to 600 rounds per minute.
The MG 08 is a heavy machine gun (HMG) which served as the standard HMG of the Imperial German Army during World War I. It was an adaptation of Hiram Maxim's 1884 Maxim gun design, and was produced in a number of variants during the war. The MG 08 also saw service during World War II in the infantry divisions of the German Army, although by the end of the war it had mostly been relegated to second-rate "fortress" units.
The MG 3 is a German general-purpose machine gun chambered for the 7.62×51mm NATO cartridge. The weapon's design is derived from the World War II era MG 42 that fired the 7.92×57mm Mauser round.
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance.
The Mle 1914 Hotchkiss machine gun chambered for the 8mm Lebel cartridge became the standard machine gun of the French Army during the latter half of World War I. It was manufactured by the French arms company Hotchkiss et Cie, which had been established in the 1860s by American industrialist Benjamin B. Hotchkiss. The gas-actuated Hotchkiss system was first formulated in 1893 by Odkolek von Ujezda and improved into its final form by Hotchkiss armament engineers, American Laurence Benét and his French assistant Henri Mercié.
The Pulyemyot Maksima PM1910, or PM M1910, is a heavy machine gun that was used by the Imperial Russian Army during World War I and the Red Army during the Russian Civil War and World War II. Later the gun saw service in the Korean War, the Vietnam War and the 2022 Russian invasion of Ukraine.
A medium machine gun (MMG), in modern terms, usually refers to a belt-fed machine gun firing a full-powered rifle cartridge, and is considered "medium" in weight. Medium machine guns are light enough to be infantry-portable, but still cumbersome enough to require a crew for optimal operational efficiency.
The Maschinengewehr (Schwarzlose) M. 7, also known as the Schwarzlose MG, is a medium machine-gun, used as a standard issue firearm in the Austro-Hungarian Army throughout World War I. It was utilized by the Dutch, Greek and Hungarian armies during World War II. It was routinely issued to Italian colonial troops, alongside the Mannlicher M1895 rifle.
The Maxim M/32-33 is a Finnish modification of the Russian M1910 Maxim, developed by Aimo Lahti in 1932. Lahti was ordered to adapt the Maxim so that it could be fed with more modern metallic ammunition belts as opposed to the original cloth belts. The resulting weapon was able to fire at a rate of 850 rounds/min, whereas the Russian M1910 and earlier Finnish M09-21 were only capable of 600 rounds/min. The increased rate of fire was achieved through improvements that included an accelerator mechanism and muzzle booster. Other changes included a redesign of the Maxim M/32-33's grips and rear sights, as well as an installation point for an optical sight.
The M1919 Browning is a .30 caliber medium machine gun that was widely used during the 20th century, especially during World War II, the Korean War, and the Vietnam War. The M1919 saw service as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S and many other countries.
