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.
Tanks a Million
Tanks a Million is a 1941 American film directed by Fred Guiol. It was the first of Hal Roach's Streamliners, short films under an hour designed for the lower half of a double feature. The film was also the first pairing of William Tracy and Joe Sawyer in a film series of the two in the military. Despite the title and military setting, no tanks are seen in the film.
