im going with Mudderchuck the purpose in the military if you are in a firefight or assaulting a objective then if you kill the a member of the Opfor then its just one man down and one less gun so say you got 10 guns firing down on you then there is still 9 more but if you wound a guy then it takes him out of the fight and then 2 to 4 other guys there eliminating more guns since they got to help their buddy get back to safety and try to fix him up so out of 10 guns you could be down to 6or 7 there fore if overpowing them makes the Opfor to fall back and reorganize allowing you to puh forward even more now on the hunting side your looking to put em down quick and efficiently
hope it helps paint a better picture for you
