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.
The Beast (1988 film)
The tank's crew is made up of four Soviets and an Afghan communist soldier. As night falls and the crew sets up camp, the Afghan tank crewman Samad (Erick Avari) educates the tank driver, Konstantin Koverchenko (Jason Patric), about the fundamental principles of "Pashtunwali", the Pashtun people's code of honour: "milmastia" (hospitality), "badal" (revenge), and "nanawatai", which requires even an enemy to be given sanctuary if he asks. As the plot progresses, Commander Daskal (called "Tank Boy" during World War II for destroying a number of German tanks when he was a child soldier during the Battle of Stalingrad) demonstrates his ruthlessness not only to the enemy, but also to his own men. He despises Samad for his ethnic association to the enemy and, after a couple of attempts to kill him, finally gets his wish on the pretext of suspecting Samad of collaborating with the mujahadeen. After Koverchenko threatens to report Daskal for the killing, Daskal entraps him and orders Kaminski (Don Harvey) and Golikov (Stephen Baldwin) to tie him to a rock, with a grenade behind his head to serve as a booby-trap for the mujahideen. Some wild dogs come upon him and as Koverchenko tries to kick at them, the grenade rolls down the rock and explodes, killing several dogs but leaving Konstantin unhurt. A group of women from the village, who had been trailing the mujahideen to offer their support, come across Koverchenko and begin to stone him, calling for his blood as revenge ("badal"). As the mujahideen approach, Koverchenko recalls the term "nanawatai" (sanctuary) and repeats it until Taj cuts him free, and allows him to follow their procession. That night, hidden in a cave, the fighters eat and Taj asks Koverchenko in broken language if he will fix their non-functioning RPG-7, and help them destroy the tank.
