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 First Class Ray Ora Riley, United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as a Platoon Sergeant of a 75-mm. Recoilless Rifle Platoon with Company M, 3d Battalion, 27th Infantry Regiment, 25th Infantry Division. Sergeant First Class Riley distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Sobuk-san, Korea, on 18 September 1950. Company L, 27th Infantry Regiment, was in position on Sobuk-san Mountain when the enemy launched a strong attack on the company area, overrunning the right flank. Observing the plight of the company, Sergeant Riley left his platoon and reorganized the surviving men of Company L for a counterattack on the enemy. Then, personally leading a group of twenty-five men armed only with rifles and grenades, he closed with a fanatical enemy of approximately company strength. Inspired by the brilliant leadership and courageous example of Sergeant Riley, the small group of men valiantly assaulted the hostile force, killing numerous enemy troops and regaining the positions which the enemy had overrun. As additional enemy troops began attacking the position from the opposite side of the hill, Sergeant Riley moved to an abandoned enemy machine-gun emplacement and turned the weapon the advancing horde. When the attacking force was finally repulsed, twenty-five enemy dead were counted in front of his machine-gun. Sergeant Riley then established a defense perimeter capable of holding the left flank of the company, utilizing the remaining members of his original group and a few reinforcement that had moved up. Throughout the night he moved among his men, keeping them on the alert and prepared for an imminent enemy counterattack. Shortly before daybreak the expected attack occurred, but was successfully repulsed with tremendous losses to the enemy. The extraordinary heroism displayed by Sergeant First Class Riley on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
