I am looking for some help figuring out what my grandpa's duty was in WWII. I know he was Amy Air Corp, but that's it. I was given his uniform and have a copy of his discharge. He served from Feb 42- Sep 45. He was a Cpl, organization was says 27th Fighter group, and military occupational specialty was Chief of section 539. On his uniform he had a a 9th Air Force badge, his hat had a Intelligence Strength emblem, also he was awarded the EAMA Theater ribbon with 7 bronze stars, and Distinguished Unit Citation with 4 Oak leaf clusters. I never got to know him and he only had 2 daughters and always said that his girls didn't need to know about war, that's how my mom always says he told them. We appreciate any help you can give us.
