First Lieutenant, 143rd Infantry Regiment, 36th Infantry Division, U.S. Army. Entered the service from Texas. Awarded the Distinguished Service Cross, the Silver Star, the Bronze Star, and the Purple Heart with Oak Leaf Cluster.

From his Distinguished Service Cross citation:

For extraordinary heroism in connection with military operations against an armed enemy while serving with the 143d Infantry Regiment, 36th Infantry Division, in action against enemy forces on 29 August 1944, near La Coucourde, France. In the early morning a strong hostile force supported by tanks penetrated the defensive position of his regiment. Lieutenant Clemens, reconnaissance officer, volunteered to lead a counterattack. Fearlessly exposing himself to small-arms, artillery, and tank fire he went to one of the guns of the cannon company which had been surrounded by the enemy. By radio he ordered three self-propelled guns into position for mutual support and going from gun to gun he personally directed their fire. Lieutenant Clemens organized the extra men of the gun crews and courageously led them in close fighting against enemy infantry. Under his heroic leadership his command destroyed one enemy tank, two antitank guns, a large number of trucks, and other motor vehicles completely blocking the road and trapping the remaining Germans. His intrepid actions prevented a serious break-through in the regimental defenses. First Lieutenant Clemens' inspiring leadership, personal bravery and zealous devotion to duty at the cost of his life, exemplify the highest traditions of the military forces of the United States and reflect great credit upon himself, the 36th Infantry Division, and the United States Army.
