Dear Mr. Holstein,
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 also may fax the form to 314-801-9195. 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 coronavirus public health emergency, the National Personnel Records Center is servicing only urgent requests related to homeless veterans, medical emergencies, and funerals which may be faxed to 314-801-0764. We thank you for your patience and look forward to resuming normal operations when the public health emergency has ended.
The information you seek may be contained in his Individual Deceased Personnel File (IDPF). For the IDPFs from 1940-1976 of personnel with surnames that begin with M-Z, please write to U.S. Army Human Resources Command, Casualty & Memorial Affairs Operations Division, ATTN: AHRC-PDC, 1600 Spearhead Division Avenue, Department 450, Fort Knox, KY 40122-5405.
We searched online and located the following sources which provide information about his service.
We hope this is helpful.
