Pistolet Maszynowy Dywersyjny
Pistolet maszynowy dywersyjny (often abbreviated p.m.d., literally: ''Machine pistol, diversionary'') is a name applied to a Polish prototype compact submachine gun or machine pistol design. As the name suggests, the weapon was intended as a light-weight, small and reliable firearm intended as a primary weapon of sabotage squads. The basic requirements for such a weapon were drawn by February 1939, the prototype was to be completed by November of that year by the Instytut Techniczny Uzbrojenia Military Institute of Armament Technology ( pl, Wojskowy Instytut Techniczny Uzbrojenia; WITU) is a Polish scientific institution responsible for the research and development of new technologies for use by the military. It is based in Zielonka at th ... institute. The weapon was to use 7.63 x 25mm Mauser cartridges. However, the outbreak of World War II prevented the completion of the prototype and it never left the drawing boards. Because of that, it never received official military design ...

Submachine Gun
A submachine gun (SMG) is a magazine-fed, automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun (hence the prefix " sub-"). As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns. The submachine gun was developed during World War I (1914–1918) as a close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of SMGs were made for use by regular troops, clandestine commandos and partisans alike. After the war, new SMG designs appeared frequently.Military Small Arms Of The 20th Century. Ian Hogg & John Weeks. Krause Publications. 2000. p93 However, by the 1980s, SMG usage decreased. Today, submachine guns have been largely replaced by assault rifles, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Pistol
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 Repetierpistole' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabotage
Sabotage is a deliberate action aimed at weakening a polity, effort, or organization through subversion, obstruction, disruption, or destruction. One who engages in sabotage is a ''saboteur''. Saboteurs typically try to conceal their identities because of the consequences of their actions and to avoid invoking legal and organizational requirements for addressing sabotage. Etymology The English word derives from the French word , meaning to "bungle, botch, wreck or sabotage"; it was originally used to refer to labour disputes, in which workers wearing wooden shoes called interrupted production through different means. A false etymology, popular but incorrect account of the origin of the term's present meaning is the story that poor workers in the Belgian city of Liège would throw a wooden into the machines to disrupt production. One of the first appearances of and in French literature is in the of d'Hautel, edited in 1808. In it the literal definition is to 'make nois ...

Instytut Techniczny Uzbrojenia
Military Institute of Armament Technology ( pl, Wojskowy Instytut Techniczny Uzbrojenia; WITU) is a Polish scientific institution responsible for the research and development of new technologies for use by the military. It is based in Zielonka at the outskirts of Warsaw. Subordinate to the Ministry of National Defence, the institute is considered one of "central institutions", that is one of state-owned institutions essential to the functioning of the state. History The institute was founded 25 March 1926 as the Institute for Artillery Research ( pl, Instytut Badań Artylerii). The new institution consisted of three departments dubbed centres: Centre for Field Studies (later renamed to Centre for Ballistic Studies) in Zielonka, Centre for Laboratory Research and the Technical Bureau. In 1935 the institute was renamed to Institute of Armament Technology ( pl, Instytut Techniczny Uzbrojenia; ITU). As one of the principal centres for research and development of weapons, the ITU was resp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
