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.

In California these engines are staffed with one firefighter and used for patrols; for this reason the unit itself is sometimes called a patrol truck or simply "patrol". Most other dispatch areas require the Type 6 to have a minimum of 3 personnel (required by NWCG policies), and is more popular outside of California due to its ability to go where other engines cannot.
