You picked Navy or did you go private industry? My dad turned it down and went immediately into NASA - as a aquanaut. He said he will never forget the day he turned down the Marine commission he was berated like a school child.
Wow! That is so cool! I chose Navy. As far as I could see it was the most technologically savvy of all the services, including the Air Force (in which my father’s brother was a lifer and did some cool stuff).
