This report provides gunner head acceleration data from the live firing of 105 mm and 152 mm turret guns on the M-551 and M-60 tanks. The head accelerations were measured with a gunner volunteer and with an anthropomorphic dummy with stationary tanks. The head acceleration values ranged from 4 Gs in the heavy M-60 tank up to 14 Gs in the light M-551 tank. A comparison of these acceleration levels to the known human tolerance data indicates no problem for single exposures for most gunners, but it is possible that some gunners will experience headaches and neck strain. The effect of repeated exposures at the 14 G level is not known and further research is recommended.
