I'll try to not be obtuse because I imagine your time is valuable  but a female who has her genitalia altered courtesy of the U.S. taxpayer  more than likely wll have a problem when it comes to some of the physical demands of being a soldier on a par with the rest of her male unit.
Women don't have to meet the same performance on PT tests that males do.
Does he get an exception that everyone else in his unit doesn't get?
Rather than sitting on a couch typing noble thoughts how would you like to have your life depend on this social experiment?
