World of Tanks

World of Tanks is a massively multiplayer online game developed by Belarusian-Cypriot company Wargaming, featuring early to mid-20th century era fighting vehicles. 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 focus is on player vs. player gameplay with each player controlling an armored vehicle, which may be a light, medium or heavy tank, tank destroyer, or self-propelled gun. World of Tanks debuted as an eSports game at the World Cyber Games 2012.

On 10 June 2013 it was announced that World of Tanks was coming to Xbox Live Arcade on 12 February 2014 as World of Tanks: Xbox 360 Edition. Xbox 360 players use separate servers to those playing the Windows version, and players of each version have separate accounts. The Xbox 360 version was developed by Wargaming West studio. An Xbox One version has been announced, and was released on 28 July 2015. A PlayStation 4 version is scheduled to release in 2016.World of Tanks has also recently expanded to mobile platforms under the name World of Tanks Blitz, in addition to a board game titled World of Tanks Rush and a collectable card game titled World of Tanks: Generals.

KV-13

The KV-13 was an experimental Soviet medium tank created during World War II. It was developed on the KV-1 chassis in the SKB-2 design bureau of the Chelyabinsk Kirov Plant in late 1941 – early 1942, as a "universal" tank, intended to replace the production of T-34 medium tanks and KV-1 heavy tanks at the same time.

Development

The first prototype of the KV-13 was made in the spring of 1942, but in the fall of that year tests showed a lack of mechanical reliability and demonstrated the need to strengthen the vehicle's armour and to equip it with the new three-seat turret. While production of two modified prototypes incorporating these modifications began in December 1942, work on the KV-13 as a medium tank was discontinued in favour of continuing the production of the T-34. The further development of the project using two modified KV-13 prototypes led to the creation in 1943 of the IS-1 heavy tank.

Tank

A tank is a large, heavily armoured fighting vehicle with tracks and a large tank gun that is designed for front-line combat. Modern tanks are mobile land weapon platforms, mounting a large-calibre cannon in a rotating gun turret. They combine this with heavy vehicle armour which provides protection for the crew, the vehicle's weapons, and its propulsion systems, and operational mobility, due to its use of tracks rather than wheels, which allows the tank to move over rugged terrain and be positioned on the battlefield in advantageous locations. These features enable the tank to perform well in a tactical situation: the combination of powerful weapons fire from their tank gun and their ability to resist enemy fire means the tank can take hold of and control an area and prevent other enemy vehicles from advancing. In both offensive and defensive roles, they are powerful units able to perform key primary tasks required of armoured units on the battlefield. The modern tank was the result of a century of development from the first primitive armoured vehicles, due to improvements in technology such as the internal combustion engine, which allowed the rapid movement of heavy armoured vehicles. As a result of these advances, tanks underwent tremendous shifts in capability during the World Wars of the 20th century.

World

World is a common name for the whole of human civilization, specifically human experience, history, or the human condition in general, worldwide, i.e. anywhere on Earth or pertaining to anywhere on Earth.

In a philosophical context it may refer to:

In a theological context, world usually refers to the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts.

World history is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present.

World population is the sum of all human populations at any time; similarly, world economy is the sum of the economies of all societies (all countries), especially in the context of globalization. Terms like world championship, gross world product, world flags etc. also imply the sum or combination of all current-day sovereign states.

Medium tank

Medium tank was a classification of tanks, primarily used during World War II. The medium tank, as the name suggests, represented a compromise in features between the reconnaissance and mobility oriented light tanks and the armor and armament oriented heavy tanks. The most widely produced, cost effective and successful tanks of World War II (the Soviet T-34, the American Sherman tank and the German Panzer IV) were all medium tank designs, and the success of the concept would later lead to the development of the main battle tank (which sought to incorporate the best aspects of all three tank types).

History

The first tanks to carry the name Medium appeared in the First World War with the British Medium Mark A "Whippet". It was smaller and lighter than the British heavy tanks and only carried machine guns.

The medium tank doctrine came into use in the interwar period. Its existence outlasted the super-heavy tank and heavy tank and graduately transitioned into the main battle tank.
