Ever hear of Rick Rescorla?
He enlisted in the US Army then attended Officer Candidate School and became a Commissioned Officer, fought at the Ia Drang with the Seventh Nav under Colonel Hal Moore....and did not receive his US Citizenship until AFTER his Combat Tour in Vietnam....retired as a Colonel and died on 9-11 getting his fellow Morgan Stanley employees out of the World Trade Center.
