I agree that in strategic missiles, pilots, and such that, yes women can do it. It is not a function of intellectual ability. Infantry soldiers are specifically trained to kill. I have commanded numerous combat units and know this. I need a human being who can lift great weight, endure punishing environments, kill an opponent on command or on their own - sometimes with their bare hands. I need a person who can lift and carry to safety 95% of the people in the unit when they are wounded. I need a person who will not be a romantic distraction. I need a person who cannot get pregnant and therefore be sent home. We need men in infantry units. Men bond well with each other, they are the perfect gender for warfare as history has taught us.
