The Defense Superior Service Medal is a prestigious military award presented by the United States Department of Defense. It recognizes members of the armed forces for exceptional service in a position of significant responsibility. The medal is typically awarded for sustained superior performance over a period of time, rather than for a single act of heroism. Established in 1976, the medal is often given to senior military personnel who demonstrate outstanding leadership and contributions to national security. Recipients may include officers from the Army, Navy, Air Force, Marine Corps, and Coast Guard, reflecting their commitment to excellence in service.
