Re: What unit did he serve in?
An individual usually filed a copy of his separation papers with the city and/or county clerk to prove eligibility for local veterans' bonus. If your state, county, etc., paid no bonus, there'll probably be no papers. Also, the unit listed in your subject's separation papers is the unit to which he was assigned while awaiting discharge. This may or may not be the unit he served with overseas (it usually isn't). Since enlisted men were seldom - if ever - entrusted with their own records, the unit listed was most often merely the custodian of the individual's records while he was being processed out. In many cases, this was a purely "paper" assignment inasmuch as the individual went home on terminal leave and saw little - if any - actual duty with the unit.
