Should there be any limits on what women can do in military?

No. I'm retired Army and have worked with women soldiers. I have seen the ones that are useless and I have seen the hard workers (and can say the same thing about the guys). In Iraq I watched a timid young girl turn into a hard charging soldier ordering Iraq prisoners around better then many guys and without back-up. And for Mr Byrd the Army demands a lot more than 3 push-ups for women.
