I commend your time in service to your country, and am sure that had I worked with you I would have been pleased, you sound like a diligent worker and to be a slacker so to speak would be out of caracter for you. Unfortunately many , not all, but enough of the females I came into contact with in the militarywere slackers who played the system milked it for all they could and were perfect slackers. Pregnancy would not allow them to drive a HUMVEE in garrison, but they could drive thier 4x4 Fords to and fro cross country. Being female would warrant easier positions, better shifts and should they decide they didn't care to go to Korea unaccompanied for a year, they got pregnant while husbands with wives having complicated pregnancies had to go.
My last tour in Bosnia I served with several females there who were great, carried their weight, and never slacked.
I personally believe there should be one set of standards in the military to provide for true unifomity. Those who meet the standard are retained, those who don't are put out, male and female alike. Open all fields to both sexes under those standards and see what happens.
