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.
Iron Tank
The tank is controlled by a standard NES controller: Directional buttons control the tank's movement, "A" fires the tank's machine-gun, "B" fires the main gun, "Start" pauses the game on the main screen, and "Select" opens the in-game menu. The turret can point in the standard 8 directions and is rotated by simultaneously pressing "A" and the desired direction. The turret will maintain its direction on the screen regardless of the tank's movements or facing and using this is part of the game's strategy.
