If I remember correctly ... he was an AOC (??? or NAVCAD ?) ... which I believe included a "placeholder" enlisted service # and rate -- usually Seaman Deuce. 'Cause if you really screwed up -- that's where and how you were going .....
But that should NEVER be construed as a real "enlisted" service nor rate a medal/ribbon.
I have an enlisted service # and discharge certificate ... when we were sworn in as Officers ... we were simultaneously "discharged" from the Navy as a Seaman Deuce and "commissioned" as an Ensign.
Same here.. NAPS.. counted as 11 months & change "enlisted".. for pay purposes only. Seaman Apprentice. Basically so Big Daddy Navy could own, and subsequently pay, us for the school year. I was simultaneously "discharged" and appointed a Midshipman. Had I not shown up to USNA... next stop, Great Lakes.
