Welcome to the forum Jack, glad to have you aboard! Here are a couple of things that might get you started. Look at box #30 on your father's discharge paper entitled "Military Occupational Specialty and No.". This would be his job title and code number for that particular job. You can look that up on the following link to get a description for what his duties would have been within the unit.
Here is a link to a thread on this forum about the 393rd that I think you'll find some interesting reading.

Hope this has helped you some, I'm sure others will chime in with more suggestions. Good luck with your search Jack!
