The Army and the Air Force retired its health records with the Official Military Personnel File, while the Department of the Navy (including the Navy, Marine Corps and Coast Guard) retired these files separately to the NPRC until the 1980s. In the past, all of the military services retired the individual health record, along with the personnel record, to the NPRC upon a service member's separation from service. Many OMPFs contain both personnel and former active duty health records, but the service branches discontinued retiring the health record portion to the NPRC in the 1990s. The Official Military Personnel Files (OMPF), held at the National Personnel Records Center (NPRC), are administrative records containing information about the subject's military service history.
