His 2nd Silver Star Citation reads:

Staff Sergeant Randy S. McComb distinguished himself by gallantry in connection with military operations against an opposing armed force during the Prisoner of War Search and Rescue Operation at Son Tay, North Vietnam, on 21 November 1970. On that date, Sergeant McComb performed aircrew duties on the lead aircraft of the force penetrating deep into enemy territory in the attempted rescue effort. Completely aware of the enemy antiaircraft and surface-to-air missile threats enroute and in the objective area, Sergeant McComb totally disregarded his personal safety and skillfully performed his duties which significantly contributed to effective control of the entire force. As a result of Sergeant McComb's heroic efforts, the force arrived at Son Tay as planned, the enemy forces were completely surprised, and the mission was successfully completed. By his gallantry and devotion to duty, Sergeant McComb has reflected great credit upon himself and the United States Air Force.
