Which organization is responsible for storing and maintaining veterans' service and health records?

The National Archives and Records Administration (NARA) is the correct organization responsible for storing and maintaining the service records of military veterans, including their health records. NARA's mission includes managing federal records, and it specifically has a division that handles the archival records of military personnel. This includes sorting, preserving, and making available the service-related documents of veterans who have served in the armed forces.

The Department of Defense typically focuses on active military personnel and their immediate records during service, rather than maintaining archival records for veterans. Although the Veterans Affairs Administration provides many services and benefits to veterans, it does not serve solely as the archival entity for military service records. Additionally, while organizations like the American Legion provide support, advocacy, and assistance to veterans, they do not have the same role in the preservation of official service records as NARA.
