The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Sergeant Roscoe Calvin Halterman, United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving with Company C, 89th Medium Tank Battalion, 25th Infantry Division. Sergeant Halterman distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Koan’g-u, Korea, on 7 March 1951. On that date, while on a tank patrol behind enemy lines, Sergeant Halterman sighted an enemy strong point which was blocking the advance of friendly forces. Knowing that the terrain precluded the use of tank weapons, Sergeant Halterman, armed with a submachine gun, dismounted and ran across approximately 200 yards of open ground to attack the objective from the rear. Raking the emplacements with submachine-gun fire, he inflicted several casualties and so completely demoralized the 30 remaining enemy troops with this daring attack that they threw down their weapons and surrendered. The fearless and aggressive action of Sergeant Halterman in single-handedly attacking and capturing the enemy against tremendous odds enabled the friendly forces to continue their advance. His extraordinary heroism on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
