Military identification refers to the official documents or cards issued to members of the armed forces, including active duty personnel, reservists, and veterans. These IDs serve as proof of service and can grant access to military facilities, benefits, and services. Typically, military identification includes essential information such as the service member's name, rank, branch of service, and a unique identification number. It may also feature a photograph and security features to prevent unauthorized use. Common examples of military identification include the Common Access Card (CAC) for active personnel and the Veteran Health Identification Card (VHIC) for veterans.
