Dear Mr. Pelfrey,
Thank you for posting your request on History Hub!
We suggest that you request a copy of his Official Military Personnel File (OMPF). Official Military Personnel Files (OMPFs) and individual medical reports for those who served in the U.S. Army after 1958 and prior to October 16, 1992 are in the custody of NARA’s National Personnel Records Center in St. Louis. Please complete a GSA Standard Form 180 and mail it to NARA’s National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. You can also fax the form to 314-801-9195 OR view the record by visiting the NPRC Archival Research Room in St. Louis, MO. Certain information in the records is not available to the general public without the written consent of the veteran or his next of kin. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
We hope this is helpful.
