ok well then allow the first gunner reign over the positions and any other gunners are forced into certain positions. say, first gunner is always allowed the tail top and bottom, let the 2nd gunner have the waists and nose... then if 3rd gunner in, force the 2nd gunner to the nose and the 3rd the waists. 4th gunner takes top or bottom, 5th takes the other. the entire time allowing gunner number one into free positions and using the slaved guns...
