Tank
With World War II the multi-turreted tanks proved impracticable, and as the single turret on a low hull design became standard, crews became standardized around a crew of four or five. In those tanks with a fifth crew member, usually three were located in the turret (as described above) while the fifth was most often seated in the hull next to the driver, and operated the hull machine gun in addition to acting as a co-driver or radio operator. Well-designed crew stations, giving proper considerations to comfort and ergonomics, are an important factor in the combat effectiveness of a tank, as it limits fatigue and speeds up individual actions.
Tank (video game)
"Tank" is a two-player maze game in which the players, each controlling a tank, attempt to shoot each other. The maze is a set of blocks set at right angles to each other with an empty square central area all viewed from above; the shape of the maze is not symmetric, and is the same between games. One of the tank sprites is white and the other is black, while the central area is filled with black X marks representing land mines. The tanks can fire shells, which destroy the other tank if they hit; tanks are also destroyed if they hit a land mine. The destruction of a tank grants the opposing player a point and causes a brief explosion and accompanying sound, during which time the other tank cannot shoot, before restoring the tank at the same position. Destroyed land mines do not return. Points are displayed above the play area, and flash during the final twenty seconds of the round. The game continues until the time runs out, after which the player with the higher point value wins the match. Each game typically costs a quarter and lasts for 60 seconds, but an internal toggle adjusts it to two quarters and 120 seconds. The time can be further adjusted by operators.
