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 Sergeant Johnny Miller, Jr. (ASN: RA-16314225), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving with a machine gun section of Company H, 2d Battalion, 7th Cavalry Regiment (Infantry), 1st Cavalry Division. Sergeant Miller distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Waegwan, Korea, on 3 September 1950. On that date, Company F, Seventh Cavalry Regiment, with an attached machine-gun section from Company H, was defensively deployed on Hill 300 near Waegwan when elements of a hostile division launched a mass attack against the hill, preceded by a heavy artillery and mortar barrage. When it became apparent the hill could not be held against the numerically superior enemy force, the company was ordered to withdraw. Sergeant Miller, section sergeant of the machine-gun section attached to the company, and two comrades volunteered to remain behind and cover the withdrawal. He remained in position delivering accurate, withering fire into the ranks of the advancing enemy until his gun emplacement was overrun, then began throwing grenades and engaging the enemy in hand-to-hand combat. When the company launched a counterattack later in the day and regained the hill, Sergeant Miller was found dead beside his machine-gun and the surrounding area was littered with enemy dead. The extraordinary heroism displayed by Sergeant Miller on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
