The President of the United States of America, authorized by Act of Congress, July 8, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Silver Star to Platoon Sergeant Joseph Wilfred Rounseville (ASN: RA-12442023), United States Army, for gallantry in connection with military operations against an opposing armed force while serving with Company C, 2d Battalion (Airborne), 502d Infantry Regiment, 1st Brigade, 101st Airborne Division, in the Republic of Vietnam. Platoon Sergeant Rounseville distinguished himself on 11 May 1966 while serving as Acting Platoon Leader during a search and destroy mission near Bu Gia Map, Republic of Vietnam. While moving his platoon through dense jungle and into an assault position, Platoon Sergeant Rounseville received intense hostile fire. He immediately maneuvered his platoon up a hill against an estimated Viet Cong squad which was supported by a machine gun. Platoon Sergeant Rounseville repeatedly exposed himself to the hostile fire by moving along the assault line and directing his men. He then led his platoon forward while firing his weapon and throwing hand grenades. Platoon Sergeant Rounseville killed at least three Viet Cong, and his platoon completely routed the insurgents from their fortified positions. Through his courage and outstanding leadership, he contributed immeasurably to the success of the mission. Platoon Sergeant Rounseville’s extraordinary heroism in close combat against a hostile force was in keeping with the highest traditions of the military service and reflects great credit upon himself, his unit, and the United States Army.
