Military records are available from the National Archives. I do not know if you will be able to get what you want, but you can ask for his records. Military records can be released on the request of the veteran and his/her next of kin. If you do not specify exactly what you want you will receive only the DD form 214 separation record. If you ask for "everything" you only get the DD form 214. You want to specify that you are requesting his Special and General Orders, DA form 20 qualification record, USAREC form 105 enlistment promise statement, DA form 3072 waiver, DA form 2376 release from active duty, DA form 8286 SGLI election, DA form 1811 physical & mental status on release from active service, DD form 396 statement of personal history, DD for 4 waiver, and ask for any other enlistment forms.
