Hello Alma Stafford 
 Thank you for posting your question on History Hub! 
 To get started with your research, we would recommend that you request your brother's Official Military Personnel File (OMPF) from the National Military Personnel Record Center in St. Louis. 
 OMPFs for army personnel who were separated from the service between 1912 and 1992 are 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. 
 Veterans and next of kin of deceased veterans may use eVetRecs to request records. See eVetRecs Help for instructions. Please note that next of kin of a deceased veteran must provide proof of death of the veteran such as a copy of death certificate, letter from funeral home, or published obituary. For more information see Request Military Service Records . 
 You may also 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. If there is any information requested by the form that you do not know, you may omit it or provide estimates (such as for dates), but the more information you provide, the easier it will be to locate the correct file. For more information see Official Military Personnel Files (OMPF) . 
 Archival OMPFs, those that are 62 years and older, may also be requested by visiting the Archival Research Room at the National Archives at St. Louis . Please email stlarr.archives@nara.gov for further assistance prior to making an appointment. 
 We hope this helps with your research!
