The President of the United States of America takes pleasure in presenting the Silver Star to Sergeant Delbert W. Klein, Sr. (MCSN: 1027681), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Platoon Sergeant of Company C, First Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 29 May 1951. When the unit was subjected to murderous enemy automatic weapons and small arms fire during the attack on a strongly fortified hill position, Sergeant Klein remained exposed to the heavy fire to assist in directing the attack which completely routed the entrenched hostile force. Courageously leading two squads in a physical pursuit of the fleeing enemy, he secured a further position and supervised its consolidation. Although painfully wounded by enemy grenade fragments, he refused medical treatment and directed the establishment of the defense and the evacuation of casualties until he, himself, was ordered to be evacuated. By his aggressive leadership, daring initiative and steadfast devotion to duty, Sergeant Klein served to inspire all who observed him and materially aided in the success of the company, thereby upholding the highest traditions of the United States Naval Service.
