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.
Task Force Baum
General Patton assigned the mission to Combat Command B (CCB), 4th Armored Division, commanded by Lt. Col. Creighton Abrams. Abrams wanted to use his entire combat command (two battalions and supporting artillery) but was overruled, and instead one company of medium tanks, a platoon of light tanks and one company of armored infantry were assigned to the task force. The tank battalion commander tabbed to command the mission was ill and suggested that Baum, the battalion S-3, instead lead the task force, which set out on late evening of 26 March.Altogether the force numbered 11 officers and 303 men, 16 tanks, 28 half-tracks, and 13 other vehicles.
