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 First Lieutenant (Infantry) Marinus Bruinooge (ASN: 0-1334095), United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as a Platoon Leader with Company G, 2d Battalion, 7th Cavalry Regiment (Infantry), 1st Cavalry Division. First Lieutenant Bruinooge distinguished himself by extraordinary heroism in action against enemy aggressor forces at Konjiam-ni, Korea, on 14 February 1951. Committed to attack and secure commanding terrain tenaciously defended by a well-fortified hostile force, Lieutenant Bruinooge’s platoon was pinned down within 150 yards of its objective by intense automatic-weapons, small-arms, and mortar fire and suffered numerous casualties. After artillery and mortar fire had been placed on the enemy position, he again led his men forward, but was halted by a vicious barrage of fire from two machine-guns and an emplacement employing grenades. Making a one-man assault at approximately 1800 hours, he advanced within twenty yards and was wounded, but gallantly forged on and, after lobbing a grenade into the position, closed with the enemy and killed its four occupants. Observing the nearest machine-gun was but twenty-five yards distant, he harassed the gunners with grenades and then, fearlessly rushing forward, fired his carbine full automatic into the foxhole until he was mortally wounded. His intrepid actions retarded the onslaught, enabled evacuation of the wounded, and contributed significantly to the subsequent accomplishment of the mission. Lieutenant Bruinooge’s consummate valor and willing self-sacrifice reflect the highest credit on himself and upheld the finest traditions of the military service.
