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.

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.
