Yep. Even in training women should not be expected to train with men. I can't imagine being put against a woman in close quarters combat, hand to hand, boxing etc. This, in itself, separates men and woman and also weaker men. Woman have many important roles in the military but not in the infantry. Yes, there are some woman that can kick some men's asses but it is not the norm. It's not sexism, it's realism.
