Dear JK Evans,
Thank you for posting your question on History Hub!
We suggest that you request a copy of his Official Military Personnel File (OMPF). OMPFs for those who separated from the U.S. Armed Forces after 1958 and before October 2002 are in the custody of NARA's National Personnel Records Center (NPRC) in St. Louis. In many cases where Army and Air Force personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Navy and Marine Corps OMPFs were not affected by the fire. 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. Veterans and their next of kin also may use eVetRecs to request records. See eVetRecs Help for instructions. 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 Request Military Service Records.
Due to the COVID-19 pandemic, NPRC will continue servicing requests ONLY associated with medical treatments, burials, and homeless veterans seeking admittance to a homeless shelter. If your request is urgent, please see Emergency Requests and Deadlines. Please refrain from submitting non-emergency requests such as replacement medals, administrative corrections, or records research until NPRC returns to pre-COVID staffing levels. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Good luck with your family research!
