Imperial combat assault tank pilots or tank troopers were Imperial combat drivers specialized in operating the TX-225 GAVw "Occupier" combat assault tanks. Under Imperial occupation, the streets of Jedha were patrolled by Imperial combat assault tanks, which were operated by two of the pilots.[5] Those perched in the command seat of the vehicle, barking out orders to the combat drivers within, were the Imperial combat assault tank commanders. These troopers were also used as light infantry, trained for recon and skirmishes, and escort roles for combat vehicles.
