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.
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.
