Also I don't think the women are being assaulted by other women. Call me crazy but I didn't see that mentioned, which would mean the men are doing it just as much in the hetero world.
I'm willing to bet there are women assaulted by other women in the military, but I imagine the numbers are relatively low compared to man by man, and woman by man. Much like man by woman. It's silly to think it doesn't happen. We just don't hear about it.
