daview25 -- I think what you need to do is draft a letter from your uncle, get him to sign it, and get a copy of his complete service record from the National Archives. The process and restrictions are outlined here:

That way your family will have a permanent record of his service from the day he enlisted to the day he was demobbed.
We can help you translate the military shortforms and jargon.
