Okay, let me clarify something, because I do believe I know what I'm talking about.
I seved in Aden in 1967, during the 'Crater District incident' for mthose who don't know about it, google it, and I don't believe women would have been able to hack it, also seved in Oman, and three tours of Northern Ireland, although I think women would, for the most part, been able to hack it there.
In Afghanistan, a male dominated society, female troops surely, would be a drawback, but overall, there are plenty of 'frontline' positions for women, just, in my book, not the 'fighting frontline.
