When I was at Florida State I took a class on the Vietnam War. One requirement was you had to interview someone who had taken part in some form or fashion.
I interviewed a retired Marine who had flown Hueys in the defense of Khe Sahn. He did pretty well and won himself an award or two. When be presented at the awards by a General he was asked what his plans were. He informed the General he had intended to become a civilian. "Very well."
Later, after the ceremony the aide came to him and said "The General wants you to stay in, what will it take?" He responded, "Send me to Pensacola, give me a transition and let me fly the F-4."
He told me, laughing - "Biggest mistake of my life. I had never been around a more competitive group. I ate two hot dogs, someone had to eat five. I had a six pack of beer, someone had to down a 12 or 18 pack. I just could never win with any of those guys. It was amazing flying the airplane, but I was just in the wrong place. Everything these guys did was just so over-the-top."
