I'm going to go out on a limb and say MOST young women are not suited for a military career, especially if it includes combat.
I was approached as a senior in college to go to OCS (because of my excellent grade average, I'm sure) but I declined because I was engaged, going to be married, and wasn't at all interested. When I told Sarge about it, he laughed his head off. Of course I was annoyed at him but he was right, I would have not done well.
Yes, women are somewhat different now in that there are almost no careers that are not open to them today. However, some of us are simply NOT SUITED for this kind of work.
We've had the discussion before about unit cohesion and how a young man and a young woman involved in a romantic relationship would probably try to save their loved one and that would put the rest of the group in jeopardy.
Or how some jerk thinks he's so macho the lady next to him just can't resist him and makes crude moves that end in rape. I'd kill the bastard but fortunately I've never had to be in a situation of that sort.
Some people are just awful, and we don't need to put impressionable young people of EITHER SEX into situations like these. It's hard enough to go out and kill your enemy and stay alive without having these side issues to worry about.
