The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to Lieutenant Colonel (Medical Corps) Oren Calvin Atchley (ASN: 0-31111), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as Commanding Officer of the 7th Medical Battalion, 7th Infantry Division. Lieutenant Colonel Atchley distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Pungsan, Korea, on 24 November 1950. While at a forward command post, Colonel Atchley organized a search party to attempt to locate an ambulance with wounded men that was missing in enemy territory. The search party was attacked while he was on reconnaissance, and he was separated from the other men. On his return, without hesitation and fully aware of the odds against him, he fired on the enemy, distracting them, giving his men time to escape. When last seen he was fearlessly maintaining his stand and urging the others to withdraw. The extraordinary heroism displayed by Lieutenant Colonel Atchley on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
