The President of the United States of America, authorized by Act of Congress, July 9, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Distinguished Service Cross to Lieutenant Colonel (Armor) Robert L. Schweitzer (ASN: 0-77192), United States Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Headquarters and Headquarters Company, 1st Infantry Division. Lieutenant Colonel Schweitzer distinguished himself by exceptionally valorous actions on 11 December 1966 while serving as aerial observer during the defense of the village of Tam Da. Colonel Schweitzer received word that a Viet Cong battalion was approaching the small village and hastened to intercept the enemy. Ignoring intense fire aimed at his aircraft, he had its pilot fly low over the insurgents to accurately determine their size and deployment. Then, as his pilot landed inside the hamlet, he radioed for infantry troops and artillery and air fire support. Colonel Schweitzer alerted the hamlet’s troops and gathered civilians into bunkers just before the Viet Cong struck with devastating force. When friendly artillery rounds began coming in, he left the village to guide the strikes from the air. Two insurgents were noticed, at this time, running from a concealed tunnel entrance. Colonel Schweitzer killed both of them with a rapid burst of fire, then landed to investigate the tunnel. Fearlessly probing the underground passages alone, he discovered and disarmed four booby traps before coming upon three insurgents in a hollowed out chamber. In the brief fight, he killed two of them and captured one. After mining the tunnels for destruction, he re-boarded his helicopter with the prisoner and intelligence materials. Colonel Schweitzer the continued surveillance of the Viet Cong forces, repeatedly exposing himself to hostile fire to discover hostile maneuvers. Through his brilliant direction, the American forces and firepower were able to decisively rout the large Viet Cong unit and save the village of Tam Da. Lieutenant Colonel Schweitzer’s extraordinary heroism and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
