The tank crewmen in the Marines have a few different responsibilities, but all center around driving, maintaining and operating the weapons systems on tanks. The tank crewmen prepare the tanks, ammunition, personnel and equipment for movement and combat. The various jobs of a Tank Crewman include operating, maintaining, firing and maneuvering the 70-ton M1A1 Abrams tank.

Tank Platoon

A Marine Corps tank platoon supports ground forces, with the Marine Corps' M1A1 Abrams tank, a heavily armored tank that has a 1,500-horsepower engine.

Every Marine tank platoon has four M1A1 Abrams battle tanks. 

The typical duties of the tank platoon include preparing tanks, personnel, and equipment for movement and combat; preparation of ammunition for firing, locating targets, loading, aiming and firing of organic tank weapons, driving the tank, and performing necessary maintenance.

Tank crewmen include a tank gunner, who preps personnel and equipment as well as the tank for movement and combat, and as the title suggests, employs the tank's weapons system. The tank driver does what this title suggests, moving the tank in order to fire on targets, and has maintenance and operational responsibilities.

The tank commander oversees all operations of the tank and its crew.
