I have copies of my grandfather's WWII separation qualification record and certificate of service but haven't had any luck finding out more about the units listed on them. His certificate of service lists D Battery 117th Anti Aircraft Artillery Gun Battalion (MBL) for his organization. The separation qualification record just has a paragraph description saying he was the commanding officer of the 4334th quartermaster service company at Base M, Luzon P.I. It does list his job assignments and the last one is Intelligence Staff Officer. If anyone knows anything about either of these units or can help direct me to more information, I would greatly appreciate it. Also, if it would help I can post the actual pictures of grandpa's documents, please just let me know. Thank you.
