HK VP70
The VP70 is a 9×19mm, 18-round, trigger (firearms), double action only, Semi-automatic firearm, semi-automatic/three-round burst capable polymer frame pistol manufactured by German arms firm Heckler & Koch, Heckler & Koch GmbH. VP stands for ''Volkspistole'' (literally "People's Pistol"), and the designation 70 was for the first year of production, 1970. Design The VP70 combined a number of design features that were innovative, or at least very unusual for its time: * It was the first polymer-Receiver (firearms), framed handgun, predating the Glock pistol, Glock 17 by 12 years. At unloaded, the weapon is lighter than most metal framed pistols of the time. * It has a double-stack, double-feed magazine; double-feed magazines are uncommon for pistols even today. These magazines hold 18 rounds, a rather high capacity for its original production time. * As on the Mauser C96 and the Lahti L35, the stock was designed to be used as a holster when not mounted.

West Germany
West Germany is the colloquial term used to indicate the Federal Republic of Germany (FRG; german: Bundesrepublik Deutschland , BRD) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from eleven states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. The FRG's provisional capital was the city of Bonn, and the Cold War era country is retrospectively designated as the Bonn Republic. At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Handgun
A handgun is a short- barrelled gun, typically a firearm, that is designed to be usable with only one hand. It is distinguished from a long gun (i.e. rifle, shotgun or machine gun, etc.), which needs to be held by both hands and also braced against the shoulder to be used properly. The two most common types of handguns in modern times are revolvers and semi-automatic pistols, although other types such as derringers and machine pistols also see infrequent usage. Before commercial mass production, handguns were often considered a badge of office, comparable to a ceremonial sword. As they had limited utility and were more expensive than the long guns of the era, the few who could only afford to purchase them carried these handguns. However, in 1836, Samuel Colt patented the Colt Paterson, the first practical mass-produced revolver, which was capable of firing five shots in rapid succession and very quickly became a popular defensive weapon, giving rise to the saying, "God cre ...

Machine Pistols
A machine pistol is an autoloading pistol capable of fully automatic fire. The term can also be used to describe a stockless handgun-style submachine gun. The term is a calque of ''Maschinenpistole'', the German word for submachine guns. Machine pistols were developed during World War I and originally issued to German artillery crews who needed a self-defense weapon that is lighter than a rifle but more powerful than a standard semi-automatic pistol. This concept would eventually lead to the development of the personal defense weapon or PDW. Today, machine pistols are considered special-purpose weapons with limited utility, with their original niche being filled with either the PDW, carbines, or simply more modern semi-automatic sidearms. Contributing to their already-fringe use, without a shoulder stock and training, machine pistols can be difficult to control for all but the best shooters. The Austrians introduced the world's first machine pistol, the ''Steyr Repetierpi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

1º Batalhão De Forças Especiais
1º Batalhão de Forças Especiais (1º B F Esp) (English: 1st Special Forces Battalion) is a counter-terrorism (CT) unit of the Brazilian Army. History The Battalion was initially formed in 1957 as a jungle rescue unit. However, in 1968 it was reorganized as a special forces unit. In 1983 the unit was expanded and placed under the parachute infantry brigade structure. Role The Battalion's mission is similar to that of the Green Beret units; however, because they have the CT mission, they have modified their organization to more closely follow Britain's Special Air Service and American's Delta Force. The SF Battalion falls within the Army's Special Operations Command and is located in Goiânia. The battalion is capable of conducting its missions independently from or in conjunction with conventional forces. Battalion troops are trained in jungle warfare at the Army's CIGS jungle warfare school and in amphibious, mountain warfare, airborne, airmobile and HAHO/HALO operations. ...

On2 Technologies, formerly known as The Duck Corporation, was a small publicly traded company (on the American Stock Exchange), founded in New York City in 1992 and headquartered in Clifton Park, New York, that designed video codec technology. It created a series of video codecs called TrueMotion (including TrueMotion S, TrueMotion 2, TrueMotion RT 2.0, TrueMotion VP3, 4, 5, 6, 7 and 8). In February 2010, On2 Technologies was acquired by Google for an estimated $124.6 million. On2's VP8 technology became the core of Google's WebM video file format. History While known by the name ''The Duck Corporation'', they developed TrueMotion S, a codec that was used by some games for full motion video (FMV) sequences during the 1990s. The original office of the Duck Corporation was founded in New York City by Daniel B. Miller, Victor Yurkovsky, and Stan Marder. In 1994 Duck opened its first "satellite" engineering office in Colonie, NY under the management of Eric Ameres. Miller b ...

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

Double-action Only
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", meanin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Selective-fire
Selective fire is the capability of a weapon to be adjusted to fire in semi-automatic, fully automatic, and/or burst mode. The modes are chosen by means of a selector switch, which varies depending on the weapon's design. Some selective-fire weapons have burst fire mechanisms to limit the maximum number of shots fired automatically in this mode. The most common limits are two or three rounds per trigger pull. Fully automatic fire refers to the ability for a weapon to fire continuously until either the feeding mechanism is emptied or the trigger is released. Semi-automatic refers to the ability to fire one round per trigger pull. The presence of selective fire modes on firearms permits more efficient use of rounds to be fired for specific needs, versus having a single mode of operation, such as fully automatic, thereby conserving ammunition while maximizing on-target accuracy and effectiveness. This capability is most commonly found on military weapons of the 20th and 21st centur ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
