Aleksandr Porokhovschikov
Aleksandr Aleksandrovich Porokhovschikov () (1892 – July 27, 1941) was a Russian and Soviet military engineer, tank and aircraft inventor from Saint Petersburg, known mostly for the development of Vezdekhod, the world's first tank (resembling the modern tankette) in 1914–1915. means 'he who goes anywhere' or 'all-terrain vehicle'. Vezdekhod was also the first caterpillar amphibious all-terrain vehicle. Subsequently, Porokhovschikov added wheels to his tank for steering, making it also the first tank design to combine caterpillar and wheel forms of movement. However, the steering was ineffectual and his design rejected. As a student, he designed his first aircraft in 1909. Later in 1911, he established a workshop that manufactured simple biplanes. His personal first flight took place at the Zolitude airstrip on the outskirts of Riga. In 1914, he constructed the world's first twin-tail aircraft. The second version of the plane, named Bi-Kok, had another invention – ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, ...

Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes Surface-to-air missile, surface based, subsurface (Submarine#Armament, submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defense, Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the World War II, Second World War, the Soviet Union, and modern NATO a ...

Propaganda
Propaganda is communication that is primarily used to influence or persuade an audience to further an agenda, which may not be objective and may be selectively presenting facts to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is being presented. Propaganda can be found in news and journalism, government, advertising, entertainment, education, and activism and is often associated with material which is prepared by governments as part of war efforts, political campaigns, health campaigns, revolutionaries, big businesses, ultra-religious organizations, the media, and certain individuals such as soapboxers. In the 20th century, the English term ''propaganda'' was often associated with a manipulative approach, but historically, propaganda has been a neutral descriptive term of any material that promotes certain opinions or ideologies. Equivalent non-English terms have also la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Espionage
Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence) from non-disclosed sources or divulging of the same without the permission of the holder of the information for a tangible benefit. A person who commits espionage is called an ''espionage agent'' or ''spy''. Any individual or spy ring (a cooperating group of spies), in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law. Espionage is often part of an institutional effort by a government or commercial concern. However, the term tends to be associated with state spying on potential or actual enemies for military purposes. Spying involving corporations is known as industrial espionage. One of the most effective ways to gath ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Sea–Baltic Canal
The White Sea–Baltic Canal (russian: Беломо́рско-Балти́йский кана́л, , ), often abbreviated to White Sea Canal () is a ship canal in Russia opened on 2 August 1933. It connects the White Sea, in the Arctic Ocean, with Lake Onega, which is further connected to the Baltic Sea. Until 1961, it was called by its original name: the Stalin White Sea–Baltic Canal (''Belomorsko-Baltiyskiy Kanal imeni Stalina''). The canal was constructed by forced labor of gulag inmates. Beginning and ending with a labor force of 126,000, between 12,000 and 25,000 laborers died according to official records,Сталинские стройки ГУЛАГа.1930–53», Москва, 2005, while Anne Applebaum's estimate is 25,000 deaths. The canal runs , partially along several canalized rivers and Lake Vygozero. As of 2008, it carries only light traffic of between ten and forty boats per day. Its economic advantages are limited by its minimal depth of , inadequate for most s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solovki Prison Camp
The Solovki special camp (later the Solovki special prison), was set up in 1923 on the Solovetsky Islands in the White Sea as a remote and inaccessible place of detention, primarily intended for socialist opponents of Soviet Russia's new Bolshevik regime. The first book on the Gulag, namely, '' In the Claws of the GPU'' (1934) by Francišak Aljachnovič, described the Solovki prison camp. At first, the Anarchists, Mensheviks and Socialist Revolutionaries enjoyed a special status there and were not made to work. Gradually, prisoners from the old regime (priests, gentry, and White Army officers) joined them and the guards and the ordinary criminals worked together to keep the "politicals" in order. This was the nucleus from which the entire Gulag grew, thanks to its proximity to the first great construction project of the Five-Year Plans, the White Sea–Baltic Canal. In one way, Solovki and the White Sea Canal broke a basic rule of the Gulag: they were both far too close to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Design Bureau
OKB is a transliteration of the Russian initials of "" – , meaning 'experiment and design bureau'. During the Soviet era, OKBs were closed institutions working on design and prototyping of advanced technology, usually for military applications. The english language corresponding term for such bureau's occupation is Research and Development. A bureau was officially identified by a number, and often semi-officially by the name of its lead designer – for example, OKB-51 was led by Pavel Sukhoi, and it eventually became known as the OKB of Sukhoi. Successful and famous bureaus often retained this name even after the death or replacement of their designers. These relatively small, state-run organisations were not intended for the mass production of aircraft, rockets, or other vehicles or equipment which they designed. However, they usually had the facilities and resources to construct prototypes. Designs accepted by the state were then assigned to factories for mass production. A ...

Allied Intervention In The Russian Civil War
Allied intervention in the Russian Civil War or Allied Powers intervention in the Russian Civil War consisted of a series of multi-national military expeditions which began in 1918. The Allies first had the goal of helping the Czechoslovak Legion in securing supplies of munitions and armaments in Russian ports; during which the Czechoslovak Legion controlled the entire Trans-Siberian Railway and several major cities in Siberia at times between 1918 and 1920. By 1919 the Allied goal became to help the White forces in the Russian Civil War. When the Whites collapsed the Allies withdrew their forces from Russia by 1920 and further withdrawing from Japan by 1922. The goals of these small-scale interventions were partly to stop Germany from exploiting Russian resources, to defeat the Central Powers (prior to the Armistice of November 1918), and to support some of the Allied forces that had become trapped within Russia after the 1917 Bolshevik revolution. Allied troops landed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
