We were doing an annual test on an M2 Bradley AFV. Part of the test involved rotating the turret repeatedly in each direction. The record keeper on this particular vehicle was a girl. We told her to count the number of times we went around because if we went around more than 6 times the turret would "unscrew and pop off". When we got to 5 she started yelling "STOP!, STOP!". On the sixth rotation she started running back away from us, still yelling STOP! Even funnier stuff.
