Recruit

With ranged weapons, where you get hit is pretty important. If you get hit in the head, you're pretty much dead, unless you have a good helmet. I think that if you get hit in the groin you'd be pretty upset. So upset, even, that you might pass out. Thus my suggestion, if you shoot someone in the groin, they should be "knocked unconscious" or, if they have good armor, really really hurt. Damage could be worked out similar to head shots in that regard.
