I sent away for a copy of my grandfather's discharge papers from World War II. The records were destroyed by fire. THe form sent requested that I give info regarding my grandfather's army unit. My grandfather past 20 years ago, and the only thing his children know is that he was in the army. I have a picture of him in his uniform. I know this is a silly question, but isd there anything in a service man's uniform that would give me clues as to where he served or what he did?
