Then-Pvt. Demensio Rivera is being recognized for his actions at Changyongni, Korea, May 22-23, 1951. When the outpost area occupied by his platoon was assaulted during the night, Rivera, an automatic rifleman, held his forward position tenaciously, although exposed to very heavy fire. When his rifle became inoperative, Rivera employed his pistol and grenades, and eventually fought the enemy hand-to-hand and forced them back.
