I am looking for some help regarding my great-grandfathers Armed Guard Service. According to his Notice of Separation from US Naval Service Record, it shows under service that he was located at Armed Guard Cen (Pac). Which from my understanding that means at Treasure Island in San Francisco. However, under the Foreign and/or Sea Service during World War II it is checked "Yes". On one of the two pictures I have of him it shows him with the Asiatic-Pacific Theater Campaign Ribbon as well as the American Theater Campaign Ribbon. My question: Does being at Treasure Island count as being in the Asiatic-Pacific Theater?
