My boy did two tours of Iraq as a combat medic. The guys in his platoon took real good care of him. They did not want their medic hurt. The only weapon he carried was a 9mm side arm. He needed his hands free to work. He is also a weight lifter and they knew he could pick them up and go if they were injured. He saw some bad things while there. He came back a better man but a much different man.
He is out now and thank god he does not have to serve under Obama.
