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 Captain Roger Edwin Schemenaur, United States Air Force, for gallantry in action while engaged in military operations involving conflict with an armed hostile force while serving with the 510th Tactical Fighter Squadron, Bien Hoa Air Base, South Vietnam, in action near An Loc, Republic of Vietnam on 2 July 1966. On that date, Captain Schemenaur was number two in a flight of two F-100’s scrambled from the alert pad to support a unit of the 1st Infantry Division that was under heavy attack by the Viet Cong. Operating under a 200 to 400 foot overcast with 2 to 3 miles visibility, Captain Schemenaur made repeated low level CBU, napalm and strafing passes, some of which were within 20 meters of the friendly positions. Throughout these vulnerable low-level patterns, Captain Schemenaur was subjected to intense .50 caliber automatic weapons, .30 caliber automatic weapons, and small arms fire. By his gallantry and devotion to duty, Captain Schemenaur has reflected great credit upon himself and upheld the highest traditions of the United States Air Force.
