The President of the United States of America takes pride in presenting the Silver Star (Posthumously) to Private First Class Reginald Alvin Riley (MCSN: 533611), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Fire Team Leader in a Rifle Platoon of the First Battalion, First Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Seoul, Korea, on 27 September 1950. Voluntarily assuming command of his squad after its leader had been killed by intense hostile fire concentrated on the platoon, Private First Class Riley promptly and skillfully directed his men in delivering effective fire which inflicted numerous casualties on the enemy and relieved the pressure on his platoon. Observing a wounded Marine lying in an exposed position, he seized an automatic rifle, courageously moved through the heavy fire to aid the fallen man and directed accurate fire to furnish cover for the successful evacuation of the casualty by other platoon members. His quick initiative, indomitable fighting spirit and staunch devotion to duty reflect great credit upon Private First Class Riley and the United States Naval Service.
