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. Squad automatic weapons usually fire the same cartridge (though heavier- bullet variants are preferred) as the assault rifles or battle rifles carried by other members of the unit. This reduces logistical requirements by making it only necessary to supply one type of service ammunition to a unit. These weapons are light enough to be carried and operated by one infantryman, unlike medium machine guns (such as the M1919 Browning) that require a crew to operate at full effectiveness; or heavy machine guns (such as the M2 Browning or the DShK) which fire more powerful cartridges but are also crew-serve ...

Military Logistics
Military logistics is the discipline of planning and carrying out the movement, supply, and maintenance of military forces. In its most comprehensive sense, it is those aspects or military operations that deal with: * Design, development, acquisition, storage, distribution, maintenance, evacuation, and disposition of materiel. * Transport of personnel. * Acquisition or construction, maintenance, operation and disposition of facilities. * Acquisition or furnishing of services. * Medical and health service support. Etymology and definition The word "logistics" is derived from the Greek adjective ''logistikos'' meaning "skilled in calculating", and the corresponding Latin word ''logisticus''. In turn this comes from the Greek ''logos'', which refers to the principles of thought and action. Another Latin root, ''log-'', gave rise to ''logio'', meaning to lodge or dwell, around 1380, and became the French verb , meaning "to lodge". Around 1670, the French King Louis XIV created t ...

Magazine (firearms)
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). 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. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stripper Clip
A stripper clip (also known as a charger or charger clip, especially in British and in Commonwealth military vocabulary) is a speedloader that holds several cartridges (usually between 5 and 10) together in a single unit for easier and faster loading of a firearm magazine. Stripper clips were originally employed in infantry bolt-action rifles, such as the Russian Mosin–Nagant, the British Lee–Enfield, and the German Mauser Model 1889, Gewehr 98 and its variant the Karabiner 98k, the related US M1903 Springfield, M1917, Swiss K31 and many others. Stripper clips were also employed in newer, semi-automatic rifles with internal box magazines, such as the Soviet SKS, and the Egyptian Hakim Rifle. Stripper clips differ from ''en bloc'' clips in that they are not designed to be inserted into the weapon itself, but only to load it or its magazine. After the magazine is loaded, the stripper clip is removed and set aside for reloading, or simply discarded during combat. Gen ...

Bolt Action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madsen Machine Gun
The Madsen is a light machine gun that Julius A. Rasmussen and Theodor Schouboe designed and proposed for adoption by Colonel Vilhelm Herman Oluf Madsen, the Danish Minister of War, and that the Royal Danish Army adopted in 1902. It was the world's first true light machine gun produced in quantity and Madsen was able to sell it in 12 calibres to over 34 countries. The gun saw extensive combat usage for over 100 years, with continued use in limited quantities worldwide into the 2010s. The Madsen was produced by Compagnie Madsen A/S (later operating as Dansk Rekyl Riffel Syndikat A/S and then Dansk Industri Syndikat A/S). Design details The design dates to 1880s, with the Danish Self Loading rifle M.1888 (; ), being a precursor design. In 1883 Captain Vilhelm Herman Oluf Madsen (a Danish artillery officer), and Rustmester Rasmussen (a weapons technician at the Danish Arsenal), began working on a recoil-operated self-loading rifle; Madsen developed the idea and Rasmussen fabr ...

Weapon Platform
A weapons platform is generally any structure, vehicle or mechanism on which a weapon can be installed (via various mounting mechanisms) for optimal stability and performance. The mounted weapons, the platform and all other associated supporting equipments together form the weapon system. In more general use, a weapons platform could be structured around a gun, such as a gun turret on a ship, or bracing on an aircraft. For example, a jet aircraft is a weapons platform for missiles, bombs or autocannons, and the resultant weapon system is the fighter jet; a motorboat can serve as a weapons platform for automatic weapons, torpedoes and flamethrowers, resulting in weapon systems such as gunboats and fast attack crafts. Land vehicles, either wheeled, tracked or mixed, are also considered weapons platforms for grenade launchers, machine guns, recoilless guns and some missile launchers, which transform the vehicles into weapon systems such as armored cars (such as the Humvee), ...

Muzzle Energy
Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge. The heavier the bullet and especially the faster it moves, the higher its muzzle energy and the more damage it will do. Kinetic energy The general formula for the kinetic energy is :E_\mathrm = \frac mv^2 where :''v'' is the velocity of the bullet :''m'' is the mass of the bullet. Although both mass and velocity contribute to the muzzle energy, the muzzle energy is proportional to the mass while proportional to the ''square'' of the velocity. The velocity of the bullet is a more important determinant of muzzle energy. For a constant velocity, if the mass is doubled, the energy is doubled; however, for a constant mass, if the velocity is doubled, the muzzle energy increases ''four'' ...

DShK
The DShK 1938 ( Cyrillic: ДШК, for russian: Дегтярёва-Шпагина Крупнокалиберный, Degtyaryova-Shpagina Krupnokaliberny, links=no, "Degtyaryov-Shpagin large-calibre") is a Soviet heavy machine gun with a V-shaped butterfly trigger, firing the 12.7×108mm cartridge. The weapon was also used as a heavy infantry machine gun, where it was frequently deployed with a two-wheeled mounting and a single-sheet armour-plate shield. 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 (a dear or beloved person) in Russian-speaking countries, from the abbreviation. Alongside the American M2 Browning, the DShK is the only .50 caliber machine gun designed prior to World War II that remains in service to the present day. History Requiring a heavy machine gun similar to the M2 Browning, development of the DShK began in the Soviet Union in 1929 an ...

M2 Browning
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards 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 Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military 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 gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Machine Gun
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 (carried by one person) 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. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber ( 12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration and destructive power against covers, vehicles, aircraft and light buildings/fortifications beyond the standard-caliber ...
