You know one woman who could do this? This is your justification for changing the policy that keeps women out of comabt?
One can prove many an inane theory by cherry-picking one exceptional case to buttress his argument. Implementing inane theories in a combat setting has disastrous consequences.
It's not a theory. If there are those that can hack it according to the male standards with no privilege or special treatment, then let them (no female PT test, please). To keep them back means 1) they aren't living to their full potential and 2) we just lost an effective fighting soldier.
