Donald Vergne Potter, enlisted, may have been a reserve or National Guard unit, but I don't think so. I believe he was in a Coastal Artillery unit on Chesapeak Bay. Also served as Quartermaster officer during WWII, and as RA JAGC officer from 1949 till his death in 1966. Buried at Arlington. I have a paybook from 1942 that shows "previous service" when he enlisted, but no further information.
