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.

Vehicle support is also a prominent feature of the game. The player can operate the combat vehicles as one of the crew members. Most tanks, for example, can accommodate up to three crew members (a driver, a commander and a machine-gunner) to make them fully effective in close city fighting, however it is easy to crew a tank solo and simply switch to different positions as needed. When grouped together in a vehicle, all players in the vehicle receive points for their actions and for the actions of their fellow crew members; for example, if a player is driving a tank and the tank commander destroys an enemy tank, both the player and the commander will receive the appropriate number of points for that kill. When operating a tank solo, the player can only perform one of the roles at a time; this prevents a solo player from being able to fire, move and reload all at the same time (reloading is a task performed by the commander). The game also features artillery support in some maps which can be utilized by both squad leaders and tank commanders.
