The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to Private First Class Lorenzo Kollock (ASN: US-52022500), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving with Company B, 2d Battalion, 21st Infantry Regiment, 24th Infantry Division. Private First Class Kollock distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Pong-Dang-ni, Korea, on 14 October 1951. On that date, the company of which Private Kollock was a member, was advancing on its objective when it was stopped by heavy fire coming from a series of well-entrenched hostile hill positions. Realizing that an attack against these positions would cause many casualties to be inflicted on the friendly troops because of the deep fortification occupied by the enemy, the company commander called for a volunteer to go forward alone and eliminate the positions with a flame thrower. Private Kollock immediately stepped forward and, grasping the weapon, he moved up the slope toward the first enemy bunker. Despite the intense fire being concentrated on him, he eliminated the position, killing two of its occupants and causing others to surrender. Observing a large group of the enemy grouping to launch a counter-attack, he unhesitatingly moved forward once more and subjected them to a long burst from his flame thrower. This courageous action inflicted heavy casualties on the hostile force and broke up the attack. Those of the enemy who were not killed or injured became thoroughly demoralized and fled to the safety of their bunkers. Private Kollock then pursued them and destroyed many of them in their positions. In attempting to sweep the area clean of the enemy, he exhausted the fuel for his weapon and was cut down by enemy automatic-weapons fire. His comrades were so inspired by his fearless actions that they charged forward and overran the enemy positions. The extraordinary heroism displayed by Private First Class Kollock on this occasion reflects the greatest credit on himself and is in keeping with the high traditions of the military service.
