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 Sergeant [then Specialist Fourth Class] Dennis K. Walker, United States Army, for extraordinary heroism on 10 May 1970 while serving as a rifleman with Company D, 6th Battalion, 31st Infantry, 3d Brigade, 9th Infantry Division, in the Republic of Vietnam. On this date Sergeant Walker’s company was involved in a reconnaissance mission, when suddenly the company was engaged and pinned down by heavy enemy mortar, rocket, and small arms fire. Sergeant Walker’s element and the command element were pinned down and isolated from the main body of the company. With complete disregard for his own safety, Sergeant Walker repeatedly exposed himself to intense enemy fire as he assaulted enemy bunkers on five different occasions. During the battle, Sergeant Walker hurled grenades and directed fire at the bunker apertures. Although wounded in one of his assaults, his pace never slowed as he took charge of his element, directing their fire into the enemy positions. Seeing that the enemy was set back by his assaults, Sergeant Walker organized a landing zone for evacuation helicopters to evacuate wounded personnel. When the enemy rallied and placed intensive fire on the helicopters, he again assaulted the bunker complex exhausting his ammunition into their positions. He then returned to his position and rallied his men, leading them to the company’s main body. Sergeant Walker’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.
