General-purpose Machine Gun
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. History The general-purpose machine gun (GPMG) originated with the MG 34, designed in 1934 by Heinrich Vollmer of Mauser on the commission of Nazi Germany to circumvent the restrictions on machine guns imposed by the Treaty of Versailles. It was introduced into the Wehrmacht as an entirely new concept in automatic firepower, dubbed the ''Einheitsmaschinengewehr'', meaning "universal machine ...

Iraq War
The Iraq War (), also referred to as the Second Gulf War, was a prolonged conflict in Iraq lasting from 2003 to 2011. It began with 2003 invasion of Iraq, the invasion by a Multi-National Force – Iraq, United States-led coalition, which resulted in the overthrow of the Ba'athist Iraq, Ba'athist government of Saddam Hussein. The conflict persisted Iraqi insurgency (2003–2011), as an insurgency arose against coalition forces and the newly established Iraqi government. US forces Withdrawal of United States troops from Iraq (2007–2011), were officially withdrawn in 2011. In 2014, the US became re-engaged in Iraq, leading a new coalition under Combined Joint Task Force – Operation Inherent Resolve, as the conflict evolved into the ongoing Islamic State insurgency in Iraq (2017–present), Islamic State insurgency. The Iraq invasion was part of the Presidency of George W. Bush, Bush administration's broader war on terror, launched in response to the September 11 attacks. ...

Belt (firearm)
An ammunition belt is a firearm device used to package and feed cartridges, typically for rapid-firing automatic weapons such as machine guns. Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition. Typical capacities for man-portable weapon systems range from 50 to 300 rounds of ammunition. Variants Feed strip The "feed strip" (also referred to as an "ammo strip" or "feed tray") was initially designed in 1895, based on initial designs by Captain Baron Adolf Odkolek von Ujezda of Vienna, Austria. A feed strip is a simple rigid metal (usually steel or brass) tray, typically holding 15 to 30 cartridges that are crimped together into a row. The feed st ...

Rotating Bolt
Rotating bolt is a method of locking the breech (or rear barrel) of a firearm closed for firing. Johann Nicolaus von Dreyse developed the first rotating bolt firearm, the "Dreyse needle gun", in 1836. The Dreyse locked using the bolt handle rather than lugs on the bolt head like the Mauser M 98 or M16. The first rotating bolt rifle with two lugs on the bolt head was the Lebel Model 1886 rifle. The concept has been implemented on most firearms chambered for high-powered cartridges since the 20th century. Design Ferdinand Ritter von Mannlicher, who had earlier developed a non-rotating bolt straight-pull rifle, developed the Steyr-Mannlicher M1895, a straight-pull rifle with a rotating bolt, which was issued to the Austro-Hungarian Army. Mannlicher then developed the M1893 auto rifle which had a screw delayed bolt and later the Mannlicher M1900 operated by a gas piston. This was an inspiration for later gas operated, semi-automatic and selective fire firearms (such as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Bolt
A firearm is said to fire from an open bolt or open breech if, when ready to fire, the bolt and working parts are held to the rear of the receiver, with no round in the chamber. When the trigger is actuated, the bolt travels forward, feeds a cartridge from the magazine or belt into the chamber, and fires that cartridge in the same movement. Like any other self-loading design, the action is cycled by the energy released from the propellant, which sends the bolt back to the rear, compressing the mainspring in readiness for firing the next round. In an open-bolt gun firing semi-automatically, the bolt is caught and held at this point by the sear after each shot; and in automatic open-bolt fire, it's caught and held in this manner whenever the trigger is released. In contrast to this, in closed-bolt guns, the trigger and sear do not affect the movement of the bolt directly. Generally, an open-bolt firing cycle is used for fully automatic weapons and not for semi-automatic weapons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas-operated Reloading
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle but subsequently failed to develop that idea further. Between 1883 ...

Myanmar Civil War (2021–present)
The Myanmar civil war (Burmese language, Burmese: မြန်မာ့ပြည်တွင်းစစ်),, also known as the Burmese civil war, is an ongoing civil war since 2021. It began following Myanmar conflict, Myanmar's long-running insurgencies, which escalated significantly in response to the 2021 Myanmar coup d'état, 2021 coup d'état and the subsequent violent crackdown on Myanmar protests (2021–present), anti-coup protests.

Bougainville Conflict
The Bougainville conflict, also known as the Bougainville Civil War, was a multi-layered armed conflict fought from 1988 to 1998 in the North Solomons Province of Papua New Guinea (PNG) between PNG and the secessionist forces of the Bougainville Revolutionary Army (BRA), and between the BRA and other armed groups on Bougainville. The conflict was described by Bougainvillean President John Momis as the largest conflict in Oceania since the end of World War II in 1945, with an estimated 15,000–20,000 Bougainvilleans dead, although lower estimates place the toll at around 1,000–2,000. Hostilities concluded under the Bougainville Peace Agreement in 1998. The national (PNG) government agreed to the founding of the Autonomous Bougainville Government and to certain rights and authorities that the autonomous government would have over what became known as Bougainville Province, which includes outlying small islands in addition to Bougainville Island itself.
