General Orders No. 31 - 5 February 1951
The Silver Star is posthumously awarded to Sergeant First Class Oren S. Cooper, RA6869050, Infantry, United States Army, a member of Company A, 23d Infantry Regiment, 2d Infantry Division, who displayed gallantry in action against an armed enemy on 6 September 1950 in the vicinity of Changnyong, Korea. In the early morning hours of that date, he was a platoon sergeant in a rifle company when it was attacked by a strong enemy force. During this attack he single-handedly covered a thirty-five yard front, while holding off the attacking enemy with rifle and grenade fire for a period of more than forty-five minutes. When reinforcements arrived from the mortar section, he continued to hold the area while these men were being placed in position. Just at daylight the enemy force withdrew. Later in the same day, he was killed by enemy mortar fire, during an attack on enemy-held positions. The gallant and inspiring conduct of Sergeant Cooper on this occasion reflects great credit upon himself and fully upholds the high traditions of the military service. Entered the military service from Carterville, Missouri.
