The President of the United States of America takes pleasure in presenting the Silver Star to Master Sergeant John A. Pierce (MCSN: 902371), United States Marine Corps, for conspicuous gallantry and intrepidity while serving with Company I, Third Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 8 and 9 April 1952. When his combat patrol was subjected to heavy mortar, machine gun and small arms fire from a well-entrenched enemy force, Master Sergeant Pierce skillfully set his automatic weapons in position to provide effective covering fire. Learning that his patrol leader had not returned from the assaulted enemy position, he immediately volunteered to accompany a rescue party in an attempt to locate the missing officer and, as his group came under intense hostile fire, placed his weapons at vantage points, directing highly effective covering fire upon the opposing forces. After finding the patrol leader, he ably assisted in carrying him to friendly lines. By his inspiring leadership, outstanding courage and unswerving devotion to duty, Master Sergeant Pierce contributed materially to the success of the rescue party and upheld the highest traditions of the United States Naval Service.
