The President of the United States of America, authorized by Act of Congress, July 9, 1918 (amended by act of July 25, 1963), takes pride in presenting the Distinguished Service Cross (Posthumously) to Specialist Fourth Class Roger Allen Pederson, 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, 3d Squadron, 5th Cavalry Regiment, 1st Brigade, 5th Infantry Division (Mechanized). Specialist Fourth Class Pederson distinguished himself as a medical aidman in support of a besieged American unit. While en route to the contact area, his convoy was ambushed by an enemy force firing rocket propelled grenades and automatic weapons. Specialist Pederson leaped from his vehicle amid intense enemy fire and raced forward to treat the wounded. With enemy rounds spraying around him, Specialist Pederson treated two wounded soldiers and dragged both to safety. Although wounded in this action, he again attempted to reach another casualty. Ignoring his own wounds, Specialist Pederson began treating the casualty’s wounds when a hail of enemy bullets struck his location. Specialist Pederson shielded the soldier with his own body, sustaining additional wounds. Shortly thereafter, he succumbed to his own wounds. Specialist Fourth Class Pederson’s extraordinary heroism and devotion to duty, at the cost of his life, were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
