The President of the United States of America, authorized by Act of Congress, July 8, 1918 (amended by act of July 25, 1963), takes pride in presenting the Silver Star (Posthumously) to Specialist Fourth Class William David Smith (ASN: RA-437827144), United States Army, for gallantry in action while engaged in military operations involving conflict with an armed hostile enemy force while serving with Troop F, 1st Squadron, 9th Cavalry Regiment, 1st Cavalry Division, in the Republic of Vietnam. Specialist Four Smith distinguished himself by exceptionally valorous action on 24 March 1971 in the Republic of Vietnam. During a reconnaissance mission over a well fortified enemy bunker complex, Specialist Four Smith, the door gunner, observed several enemy soldiers as his aircraft began its descent into the hostile environment. With complete disregard for his own safety, Specialist Four Smith engaged the enemy with effective suppressive fire. As Specialist Four Smith attempted to protect the aircraft from the hostile forces, an enemy rocket struck the aircraft amidst a lethal crossfire from the enemy forces. Specialist Four Smith’s gallantry in action and devotion to duty are in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
