His 7th Distinguished Flying Cross Citation reads:

Colonel Harold E. Comstock distinguished himself by extraordinary achievement while participating in aerial flight as Senior Controller aboard the Seventh Air Force Airborne Battlefield Command and Control Center, on 7 March 1968. On that date, an unexpected improvement in weather conditions over vital North Vietnamese supply routes exposed massive concentrations of vehicles, supplies, and air defense systems. Colonel Comstock reacted immediately, providing and directing a continuous flow of air strikes into the area. Although orbiting hostile territory and working many hours under heavy stress without relief, he effectively controlled the battle, which resulted in extremely heavy losses to hostile forces. The professional competence, aerial skill, and devotion to duty displayed by Colonel Comstock reflect great credit upon himself and the United States Air Force.
