It is authorized by the United States Armed Forces for a specific set of decorations and awards of the Department of Defense, Department of the Army, and Department of the Air Force.
The bronze oak leaf cluster represents one additional award, while the silver oak leaf cluster is worn in lieu of five bronze oak leaf clusters.
