World of Tanks (WoT) is an armoured warfare-themed multiplayer online game developed by Wargaming, featuring 20th century (1910s–1970s) era combat vehicles. [1] It is built upon a freemium business model where the game is free-to-play, but participants also have the option of paying a fee for use of "premium" features.
The economic system in World of Warplanes is similar to World of Tanks and other Wargaming titles. The game features four primary types of in-game currency: credits, experience, tokens [ 4 ] (since version 1.9.4 [ 5 ] ), and gold (other kind of tokens were a temporary in-game currency used instead of gold during open beta testing stage).
Challenger 3 (CR3) is a British fourth-generation main battle tank in development for the British Army.It will be produced by the conversion of existing Challenger 2 tanks by the British/German Rheinmetall BAE Systems Land joint venture.
Development of a tank classification system started in World War I, when tanks were separated into light tanks and tankettes, medium tanks, and heavy tanks, based on size and weight. Heavy tanks were required to be large to cross trenches, and consequently weighed a lot. Medium tanks were smaller and had help to cross trenches so weighed less.
The first generation of main battle tanks was based on or influenced by designs of World War II, most notably the Soviet T-34. [4] The second generation was equipped with NBC protection (only sometimes), night-vision devices, a stabilized main gun and at least a mechanical fire-control system. [ 4 ]
U.S. combined arms doctrine on the eve of World War II held that tanks should be designed to fulfill the role of forcing a breakthrough into enemy rear areas. Separate GHQ (General Headquarters) tank battalions would support infantry in destroying fixed enemy defenses, and armored divisions would then exploit the breakthrough to rush into the enemy's vulnerable rear areas.
During the 1967 Six-Day War, U.S.-supplied M48 Patton tanks, British Centurion tanks, and even upgraded World War II–era 75 mm M-50 and 105 mm armed M-51 Super Shermans faced T-55s. This mix of Israeli tanks, combined with superior planning of operations and superior airpower, proved to be more than capable of dealing with the T-54/T-55 series.
The 70th Tank Battalion was the U.S. Army's first separate tank battalion, activated on 15 June 1940, from Regular Army troops. Four more separate tank battalions (the 191st–194th) were formed soon after from National Guard tank companies from California, Connecticut, Illinois, Kentucky, Massachusetts, New York, Ohio, Virginia, and Wisconsin.
