If Charles was an officer, he would have had to stay in the service longer than the duration. I would have expected him to remain in the service longer. You have to be clearer on that point was he a non-comm enlisted man? If he was an officer why did he leave the service? Dis he "negate" Korea the ten years in would have been 1951 and Korea was front page. He was a marine, in the Pacific, in Japan, he would have seen Korea. Officers didn't just come and go: an act of Congress is not given lightly.
