They're talking average. I've known women at the gym who could pick up the average man and throw him over their shoulders.
Women have served with distinction in combat in many venues, usually auxiliaries in cases of a shortage of men. If qualifications for a combat position is mission defined, then I can't see any rational reason for disqualifying someone based on gender.
On the other hand, if we are going to disqualify a particular sex based on who is best for a mission, then men ought to be excluded as combat pilots. Women are generally smaller, and more easily fit into cockpits and handle rapid acceleration better than do men. And, they can be extremely aggressive in combat--as the Germans found out when they faced Russia's "night witch" pilots in WWII.
