It's interesting, I've been reading up on women in combat now, and it seems that many Western military's already allow women in combat roles, and they've done exceptionally well. It's been noted that especially in places like Afghanistan and Iraq they are able to coordinate with the local female populace in a way men were never able to, therefore allowing them access to places and information the military's previously didn't have.
