Tank
Most modern tanks most often have four crew members, or three if an auto-loader is installed. These are the:
Historically, crews have varied from just two members to a dozen. For example, pre-World War II French tanks were noted for having a two-man crew, in which the overworked commander had to load and fire the gun in addition to commanding the tank. First World War tanks were developed with immature technologies; in addition to the crew needed to man the multiple guns and machine guns, up to four crewmen were needed to drive the tank: the driver, acting as the vehicle commander and manning the brakes, drove via orders to his gears-men; a co-driver operated the gearbox and throttle; and two gears-men, one on each track, steered by setting one side or the other to idle, allowing the track on the other side to slew the tank to one side.
Tank (video game)
Tank is an arcade game developed by Kee Games, a subsidiary of Atari, and released in November 1974. It was the only original title not based on an existing Atari property developed by Kee Games, which was founded to sell clones of Atari games to distributors as a fake competitor prior to the merger of the two companies. In the game, two players drive tanks through a maze viewed from above while attempting to shoot each other and avoid mines, represented by X marks, in a central minefield. Each player controls their tank with a pair of joysticks, moving them forwards and back to drive, reverse, and steer, and firing shells with a button to attempt to destroy the other tank. The destruction of a tank from a mine or shell earns the opposing player a point, and tanks reappear after being destroyed. The winner is the player with more points when time runs out, with each game typically one or two minutes long.
