The President of the United States of America, authorized by Act of Congress, July 9, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Distinguished Service Cross to Staff Sergeant Bobby Quillian Brock, United States Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company A, 1st Battalion, 5th Infantry, 25th Infantry Division. Staff Sergeant Brock distinguished himself by exceptionally valorous actions on 13 June 1969 while serving as a platoon leader of an ambush patrol on the Bau Dieu Peninsula. When an enemy force opened fire, Sergeant Brock maneuvered among his men directing fire and pointing out targets. Although wounded by shrapnel, he removed through the fusillade to an injured comrade to administer first aid. He then assisted in leading casualties on the medical evacuation helicopter, and when the aircraft was shot down while lifting off, he rushed to the wreckage and removed the crew to safety. Despite being wounded again by a rocket grenade, he directed his men into a defensive perimeter and called in supporting artillery fire to cover the approach of another ambulance helicopter. Not until all of the casualties had been extracted and a reinforcement element had arrived did he allow himself to be evacuated for medical treatment. Staff Sergeant Brock’s extraordinary heroism and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
