There was a video about this a couple of months back. I love women. They're awesome but, according to the video, even the top females were equal to probably the weakest men. The general said, in combat, you overwhelm the enemy with your best. You don't put someone out there just because the want to participate.
I think it was Gaddafi that had the all female body guard military. Those women got killed, captured, raped, and mutilated. If he wasn't stabbed in the ass and dead right now, he'd probably tell you that having an all women military security force might have been a bad idea.
