After spending about 16 hours sandblasting the tank in preparation for painting, Brian Johnson and Dieter Steinborn start taping down the M41A1 Light Tank in front of Fort Jackson's Basic Combat Training Museum Oct. 4 to begin the next process. 'We want to make sure everything that's supposed to stay black stays black when we start putting the paint on,' said Johnson. BCT Museum Collections Manager Julie Fishel said the three tanks located in front of the museum and the helicopter will undergo painting.
