His Silver Star Citation reads:

For gallantry in connection with military operations against an opposing armed force as an F-4C Pilot of the 559th Tactical Fighter Squadron, 12th Tactical Fighter Wing, Cam Ranh Bay, Vietnam, in action in Southeast Asia, on 11 November 1966. On that date, Lieutenant Ringsdorf piloted an F-4C aircraft against a target in North Vietnam. Despite known defensive weapons fire reported by other aircraft in the attacking flight, Lieutenant Ringsdorf selflessly continued his attack. With complete disregard for his own personal safety, Lieutenant Ringsdorf made low repeated passes over suspected anti-aircraft gun positions to draw their fire and expose themselves to attacks from fighter aircraft. By his gallantry and devotion to duty, Lieutenant Ringsdorf has reflected great credit upon himself and the United States Air Force.
