Greetings, everyone. New guy here, so please forgive my ignorance of protocols. My father passed away a few weeks ago. He was 95 years old. I am trying to put together information on his WW2 service for our family. Dad never liked to talk about his time overseas so we knew very little. I do have his Discharge Document and it's raising as many questions as it answers. I hope you will bear with me: 1. His Arm of Service is listed as CAC. Would that be Combined Arms Center or Coast Artillery Corps? I know he was in the 549th AAA Battalion, so I assume it's the latter but how was the Coast Artillery Corp involved in Europe? 2. His Date of Induction was 15 APR 43 and his Date of Active Service was 22 APR 43. In Remarks, it says ERC SERV 15 APR 43 to 22 APR 43 and that's mixed in with the ribbons, buttons and bars he was entitled to wear. I assume ERC is Enlisted Reserve Corps. Were draftees initially put in ERC? Was the Date of Induction the date he reported or the day he was notified? If he was in ERC, was there a ribbon or other insignia I should be looking for? 3. This is an odd one. Given the dates I mentioned, box 31 says he qualified as a RIFLE MKM 27 FEB 43. How can that be? Actually, for some reason, I thought he had said he was a Sharpshooter, but I think this says Marksman. 4. Box 40 says AR 615-365 CONV OF GOVT R R 1-1 (DEMOBILIZATION 15 DEC 44). I understand that to mean that as a draftee, he was no longer needed and was separated at the convenience of the government. What does Demobilization 15 DEC 44 mean? He arrived in the ETO on 10 OCT 44, was in the Battle of the Bulge, and departed for the USA on 20 JAN 46. So what was demobilized on 15 DEC 44? 5. Given those dates, he was in the ETO for a year after the Battle of the Bulge. Wouldn't that have made him part of the occupation forces, or could he have been reassigned to other duties for that year? Nothing is mentioned about occupation forces on the discharge document. One more: 6. I have a picture of him in what appears to be a dress uniform with no insignia except an Advance Section, Communication Zone patch on his left shoulder. I'm assuming that when he went in, he might have been assigned to the ADSEC but sometime later was moved to the 549th AAA BN. Is that a reasonable scenario? I'm hoping to get an appointment to review his records at the National Archives Records Center here in St. Louis, assuming his weren't among the 80% destroyed in 1973. Hopefully, there will be something to help piece together Dad's military life. In the mean time, I thank you for any light you can shed on my research. Thanks, Ray Jr.
