CZ Model 25
The CZ Model 25 (properly, Sa 25 or Sa vz. 48b/samopal vz. 48b – ''samopal vzor 48 výsadkový'', "submachine gun model year 1948 para") was perhaps the best known of a series of Czechoslovak designed submachine guns introduced in 1948. There were four generally very similar submachine guns in this series: the Sa 23, Sa 24, Sa 25, and Sa 26. The primary designer was Jaroslav Holeček (September, 15 1923–October, 12 1997), chief engineer of the Česká zbrojovka Uherský Brod arms factory. Design The Sa 23 series utilize a straightforward blowback action, with no locked breech, and fire from the open bolt position. They also use a progressive trigger for selecting between semi-automatic fire and fully automatic fire. Lightly pulling on the trigger will fire a single shot. Pulling the trigger farther to the rear in a continuous motion will fire fully automatically, until the trigger is released or the magazine is empty. The Sa 23 series were submachine guns with a ...

9×19mm Parabellum
The 9×19mm Parabellum (also known as 9mm Parabellum or 9mm Luger or simply 9mm) is a rimless, tapered firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, it is widely considered the most popular handgun and submachine gun cartridge due to its low cost and extensive availability. It is a standard cartridge for NATO forces as well as in many non-NATO countries. Since the cartridge was designed for the Luger semi-automatic pistol, it has been given the designation of 9mm Luger by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the Commission internationale permanente pour l'épreuve des armes à feu portatives (CIP). A 2007 US survey concluded that "about 60 percent of the firearms in use by police are 9mm arabellum and credited 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.Adler, Jerry, et al.

North Vietnam
North Vietnam, officially the Democratic Republic of Vietnam (DRV; vi, Việt Nam Dân chủ Cộng hòa), was a socialist state supported by the Soviet Union (USSR) and the People's Republic of China (PRC) in Southeast Asia that existed from 1945 to 1976 and was recognized in 1954. Both the North Vietnamese and South Vietnamese states ceased to exist when they unified as the Socialist Republic of Vietnam. During the August Revolution following World War II, Vietnamese communist revolutionary Hồ Chí Minh, leader of the Việt Minh Front, declared independence on 2 September 1945, announcing the creation of the Democratic Republic of Vietnam. The Việt Minh ("League for the Independence of Vietnam"), led by communists, was created in 1941 and designed to appeal to a wider population than the Indochinese Communist Party could command. From the very beginning, the DRV regime sought to consolidate power by purging other nationalist movements. Meanwhile, France moved in t ...

Communist
Communism (from Latin la, communis, lit=common, universal, label=none) is a far-left sociopolitical, philosophical, and economic ideology and current within the socialist movement whose goal is the establishment of a communist society, a socioeconomic order centered around common ownership of the means of production, distribution, and exchange which allocates products to everyone in the society.: "One widespread distinction was that socialism socialised production only while communism socialised production and consumption." Communist society also involves the absence of private property, social classes, money, and the state. Communists often seek a voluntary state of self-governance, but disagree on the means to this end. This reflects a distinction between a more libertarian approach of communization, revolutionary spontaneity, and workers' self-management, and a more vanguardist or communist party-driven approach through the development of a constitutional socialist state ...

Bay Of Pigs Invasion
The Bay of Pigs Invasion (, sometimes called ''Invasión de Playa Girón'' or ''Batalla de Playa Girón'' after the Playa Girón) was a failed military landing operation on the southwestern coast of Cuba in 1961 by Cuban exiles, covertly financed and directed by the United States. It was aimed at overthrowing Fidel Castro's communist government. The operation took place at the height of the Cold War, and its failure influenced relations between Cuba, the United States, and the Soviet Union. In December 1958, American ally General Fulgencio Batista was deposed by Castro's 26th of July Movement during the Cuban Revolution. Castro nationalized American businesses—including banks, oil refineries, and sugar and coffee plantations—then severed Cuba's formerly close relations with the United States and reached out to its Cold War rival, the Soviet Union. The Central Intelligence Agency (CIA) began planning the overthrow of Castro, which U.S. President Dwight D. Eisenhower appr ...

Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Gua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warsaw Pact
The Warsaw Pact (WP) or Treaty of Warsaw, formally the Treaty of Friendship, Cooperation and Mutual Assistance, was a collective defense treaty signed in Warsaw, Poland, between the Soviet Union and seven other Eastern Bloc socialist republics of Central and Eastern Europe in May 1955, during the Cold War. The term "Warsaw Pact" commonly refers to both the treaty itself and its resultant defensive alliance, the Warsaw Treaty Organization (WTO). The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (Comecon), the regional economic organization for the socialist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into the North Atlantic Treaty Organization (NATO)"In reaction to West Germany's NATO accession, the Soviet Union and its Eastern European client states formed the Warsaw Pact in 1955."

Blowback-operated
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 operation. ...

Open-bolt
A firearm is said to fire from an open bolt 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 (except some se ...

Telescoping Bolt
A telescoping bolt (also known as an overhung bolt) is a firearm bolt which telescopes over, that is, wraps around and past, the breech end of the barrel. This feature reduces the required length of a weapon such as a submachine gun significantly, and it allows rifle designs to be balanced around the pistol grip in a way that gives "pointability" similar to a pistol's. While it would be simpler and easier to shorten the bolt to fit completely behind the breech, the bolt must have a certain amount of mass in order to operate reliably with a given caliber. The telescoping bolt moves some of that mass forward of the bolt face, resulting in a bolt which may be longer overall, but is shorter behind the bolt face. Though technically a different, distinct concept, nearly all telescoping bolt submachine guns use a magazine located in the pistol grip used to hold and fire the weapon. However, there are blowback firearms with the magazine located in the grip that do not use a telescopin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Progressive Trigger
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flattened lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single-action", meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
