AA-52
The ''AA-52'' (full designation in French: ''Arme Automatique Transformable Modèle 1952'', "Transformable automatic weapon model 1952") is one of the first French-produced guns of the Aftermath of World War II, post–World War II era. It was manufactured by the French government-owned Manufacture d'armes de Saint-Étienne (MAS) company. The AA-52 is still used today as a vehicle-mounted weapon due to large quantities in service, but has been replaced in the helicopter role by the Belgian FN MAG, starting with the Eurocopter EC 725, EC 725 Caracal of the Special Operations Command (France), special operations units and the French Air Force, Air Force search and rescue teams. The AA-52 had been largely phased out for infantry use in favour of the lighter FN Minimi but remains in use. History The AA-52 general-purpose machine gun was conceived and developed following the French military's experiences in the First Indochina War during the early 1950s. At that time, the French army w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacture D'armes De Saint-Étienne
The ''Manufacture d'Armes de Saint-Étienne'', often abbreviated to MAS ("Saint-Étienne Weapons Factory" in English) was a French state-owned weapons manufacturer in the town of Saint-Étienne, Loire. Founded in 1764, it was merged into the French state-owned defense conglomerate GIAT Industries in 2001. History Saint-Étienne was well-known as a center of sword and knife manufacturing beginning in the Middle Ages. In 1665, a Royal Arms Depot was created in Paris to store military weapons made in Saint-Étienne. The ''Manufacture d'Armes de Saint-Étienne'' was created by royal decree in 1764 under the supervision of the General Inspector of the Royal Arms Manufacture of Charleville. 12,000 weapons were being produced each year when the French Revolution The French Revolution ( ) was a period of radical political and societal change in France that began with the Estates General of 1789 and ended with the formation of the French Consulate in coup of 18 Bruma ...

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 firearm, automatic firepower, dubbed the ''Einheitsmaschinengewehr'', meaning "universal machi ...

Blowback (arms)
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil operatio ...

FAMAS
The FAMAS (''Fusil d'Assaut de la Manufacture d'Armes de Saint-Étienne'', "Assault Rifle from the Saint-Étienne Weapon Factory") is a bullpup assault rifle designed and manufactured in France by MAS in 1978, a year after the Austrian Steyr AUG. It is known by French troops as ''Le Clairon'' (The Bugle) due to its distinctive shape. The FAMAS is recognised for its high rate of fire at 1,100 rounds per minute. Beginning in 2017, the FAMAS was replaced in most frontline units in the French Army by the HK416F, and the FAMAS is expected to remain in limited service until 2028. History The first French bullpup rifles were developed between 1946 and 1950 at the AME (''Atelier Mécanique de Mulhouse'') and MAS, testing rounds such as .30 US Carbine, 7.92×33mm Kurz, 7.65×38mm (Made by ''Cartoucherie de Valence'') and some other intermediate calibers. Since France was engaged in the First Indochina War at the time, and was also the second-largest contributor to NATO, the research ...

MG 42
The MG 42 (shortened from German: ''Maschinengewehr 42'', or "machine gun 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. Designed to use the standard German 7.92×57mm Mauser rifle round, be low-cost and easier to mass-produce, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges, averaging about 1,200 rounds per minute compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like the M1919 Browning, FM 24/29 or Bren gun. This ability made it extremely effective in providing suppressive fire, and its unique sound led to it being ni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Primary Extraction
In breechloading firearms, primary extraction is the initial phase (the first few millimeters) of the extraction of a spent casing from the firearm chamber. After the primary extraction comes the secondary extraction where the bolt is moved further backwards, and the extraction is then normally finished with the spent cartridge being ejected. The first few millimeters of extraction tend to require a much higher peak force than the rest of the extraction due to the spent casing sticking against the chamber walls. The sticking effect is a result from the case having expanded due to the high pressures during firing, and the extra initial force required can, depending on firearm design, make the extraction difficult for the user. Selfloading rifles usually don't have a separate motion for primary extraction, but instead depend on using a lot of force in order to start the extraction. Different designs are used for ensuring reliable extraction in manual mechanisms, with most of them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Indochina War
The First Indochina War (generally known as the Indochina War in France, and as the Anti-French Resistance War in Vietnam) began in French Indochina from 19 December 1946 to 20 July 1954 between France and Việt Minh (Democratic Republic of Vietnam), and their respective allies. Việt Minh was led by Võ Nguyên Giáp and Hồ Chí Minh. Most of the fighting took place in Tonkin in Northern Vietnam, although the conflict engulfed the entire country and also extended into the neighboring French Indochina protectorates of Laos and Cambodia. At the Potsdam Conference in July 1945, the Combined Chiefs of Staff decided that Indochina south of latitude 16° north was to be included in the Southeast Asia Command under British Admiral Mountbatten. The Japanese forces located south of that line surrendered to him and those to the north surrendered to Generalissimo Chiang Kai-shek. In September 1945, Chinese forces entered Tonkin, and a small British task force landed at city of S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FN Minimi

Search And Rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs; urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organization that promotes the exchange of information between national urban search and rescue organizations. The duty to render assistance is covered by Article 98 of the UNCLOS. Definitions There are many different definitions of search and rescue, depending on the agency involved and country in question. *Canadian Forces: "Search and Rescue comprises the search for, and provision of aid to, persons, ships or other craft which are, or are fear ...
