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.
A squad automatic weapon (SAW),also known as a section automatic weapon or light support weapon (LSW),is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns,or modified selective-fire rifles fitted with a heavier barrel,bipod and a belt/drum-fed design.
The AK-74 is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974 as a successor to the AKM. While primarily associated with the Soviet Union,it has been used by many countries since the 1970s. It is chambered for the 5.45×39mm cartridge,which replaced the 7.62×39mm cartridge of Kalashnikov's earlier automatic weapons for the Soviet Armed Forces.
The Bren gun was a series of light machine guns (LMG) made by Britain in the 1930s and used in various roles until 1992. While best known for its role as the British and Commonwealth forces' primary infantry LMG in World War II,it was also used in the Korean War and saw service throughout the latter half of the 20th century,including the 1982 Falklands War. Although fitted with a bipod,it could also be mounted on a tripod or be vehicle-mounted.
The SVD,GRAU index 6V1,is a semi-automatic designated marksman rifle/sniper rifle chambered in the 7.62×54mmR cartridge,developed in the Soviet Union.
A magazine,often simply called a mag,is an ammunition storage and feeding device for a repeating firearm,either integral within the gun or externally attached. The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a "clip",although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder.
The 7.62×54mmR is a rimmed rifle cartridge developed by the Russian Empire and introduced as a service cartridge in 1891. Originally designed for the bolt-action Mosin–Nagant rifle,it was used during the late tsarist era and throughout the Soviet period to the present day. The cartridge remains one of the few standard-issue rimmed cartridges still in military use,and has one of the longest service lives of any military-issued cartridge.
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 also commonly known as the PKM,is a belt-fed general-purpose machine gun,chambered for the 7.62×54mmR rimmed cartridge.
The RPK,sometimes inaccurately termed the RPK-47,is a Soviet 7.62×39mm light machine gun that was developed by Mikhail Kalashnikov in the early 1960s,in parallel with the AKM assault rifle. It was created to standardize the small arms inventory of the Soviet Army,where it replaced the 7.62×39mm RPD machine gun. The RPK continues to be used by the military of the post-Soviet states and certain African and Asian nations. The RPK is also manufactured in Bulgaria,Hungary,Romania,and Serbia.
The Type 11 light machine gun was a light machine gun used by the Imperial Japanese Army in the interwar period and during World War II. Adopted as the Imperial Japanese Army's first light machine gun,the Type 11 was designed by KijirōNambu and had certain similarities to the Hotchkiss series of machine guns. It had an unusual feed system which required five round clips to be dropped into a hopper,this held up to a total of six clips and each round was oiled as it was fed into the chamber. Despite good overall performance,this feed system was prone to collect dirt and grit which would jam the weapon while in use. It was issued to troops in 1922 and saw extensive service as a squad weapon until 1945.
The Type 99 light machine gun was a light machine gun used by the Imperial Japanese Army in World War II. It was similar in design to the earlier Type 96 light machine gun,but designed to fire the new and more powerful 7.7×58mm Arisaka cartridge,which improved energy by over 50%. Other improvements included the omission of the oiling mechanism which resulted in a better all-round weapon. The Type 99 never fully replaced the previous models of Japanese light machine guns,and served alongside the Type 11 and Type 96 until 1945.
The ZPU is a family of towed anti-aircraft guns based on the Soviet 14.5×114mm KPV heavy machine gun. It entered service with the Soviet Union in 1949 and is used by over 50 countries worldwide.
The PPSh-41 is a selective-fire,open-bolt,blowback submachine gun that fires the 7.62×25mm Tokarev round. It was designed by Georgy Shpagin of the Soviet Union to be a cheaper and simplified alternative to the PPD-40.
The Type 67 is a general-purpose machine gun,chambered in 7.62×54mmR formerly used by the People's Liberation Army.
The 6.5×50mmSR Arisaka is a semi-rimmed rifle cartridge with a 6.705 mm diameter bullet. It was the standard Japanese military cartridge from 1897 until the late 1930s for service rifles and machine guns when it was gradually replaced by the 7.7×58mm Arisaka.
The Type CQ is an unlicensed Chinese variant of the M16 rifle manufactured by Norinco. According to the Norinco website,the rifle is officially known as CQ 5.56.
The RPD is a 7.62x39mm light machine gun developed in the Soviet Union by Vasily Degtyaryov for the 7.62×39mm M43 intermediate cartridge. It was created as a replacement for the DP machine gun chambered for the 7.62×54mmR round. It is a precursor of most squad automatic weapons. It was succeeded in Soviet service by the RPK.
The AKM is an assault rifle designed by Soviet small arms designer Mikhail Kalashnikov in 1959. It was developed as the successor to the AK-47 adopted by the Soviet Union a decade prior.
The Type 80 is a general-purpose machine gun (GPMG) manufactured by Norinco in China,based on the Soviet PKM. The machine gun was certified for design finalisation in 1980 and entered the PLA service in the mid-1980s,specifically in 1983. The Type 80 was intended as a successor to the Chinese independently developed Type 67,doing well in tests conducted in the Chengdu Military Region before it was dropped and instead,opted to keep the Type 67 GPMG in use.
