Dear Mr. Wick,
Thank you for posting your request on History Hub!
We suggest that you request a copy of his Official Military Personnel File (OMPF). OMPFs and individual medical reports for soldiers of the U.S. Army who served during most of the 20th century in the custody of NARA's National Personnel Records Center (NPRC) in St. Louis. In many cases where 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. 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.
Military personnel records are completely opened to the public 62 years after the veteran leaves the military. If less than 62 years have passed since the veteran’s discharge date (to include any reserve time), 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 and Official Military Personnel Files (OMPF), Archival Holdings.
We hope this is helpful. Best of luck with your research!
