His 1st (of 2) Silver Star Citation reads:

For gallantry in connection with military operations against an opposing armed force as Pilot of an F-105 Thunderchief Fighter-Bomber of the 563d Tactical Fighter Squadron, in action over North Vietnam, on 27 July 1965. On that date, as a Flight Leader, Captain Berg participated in a strike against a heavily defended Surface-to-Air Missile site near Hanoi, Vietnam. This was the first attack by fighters against an operational SAM site in military history and the hazards involved cannot be overemphasized. Penetrating hostile defenses and heavy anti-aircraft fire on a low-level, high-speed run, Captain Berg courageously pressed the attack to score a direct hit on his assigned target. By his gallantry and devotion to duty, Captain Berg has reflected great credit upon himself and the United States Air Force.
