The President of the United States of America, authorized by Act of Congress July 9, 1918 (amended by an act of July 25, 1963), takes pleasure in presenting the Silver Star to Lieutenant Colonel (Infantry) William Eugene Klein (ASN: 0-70796), United States Army, for gallantry in action. Lieutenant Colonel Klein distinguished himself by heroic actions on 18 December 1968, while serving as Battalion Commander of the 1st Battalion, 5th Infantry Regiment, 25th Infantry Division, in the Republic of Vietnam. Lieutenant Colonel Klein exposed himself to the intense hostile fire while leading the battalion in an assault on the well-fortified enemy positions. With complete disregard for his own safety, Lieutenant Colonel Klein climbed atop the lead vehicle, and evacuated the wounded vehicle commander. Returning to the bullet swept area, Lieutenant Colonel Klein detected enemy movement in a hedgerow 20 meters away, and destroyed the enemy position with an M-60 machine gun. From exposed positions, he called in supporting air strikes, and gunships throughout the raging battle. Afterwards, Lieutenant Colonel Klein directed the battalion into a consolidated position, and supervised the evacuation of two personnel carriers. His valorous actions contributed immeasurably to the success of the mission, and the defeat of the hostile force. Lieutenant Colonel Klein’s personal bravery, aggressiveness, and devotion to duty are in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, the 25th Infantry Division, and the United States Army.
