I was in ROTC at North Texas.  While in the US Air Force I was a supply services officer and briefly ran the commissary, temporary housing, military clothing, troop issue MRE's, and the base gas station at Randolph AFB from 1974 to 1976.  When Vietnam ended I took off to start in my sales career.  The guy who preceded me in this job went to Vietnam, I lucked out did not have to go.  I was a 1st Lieutenant when I left.
