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 a Bronze Oak Leaf Cluster in lieu of a Second Award of the Silver Star to First Lieutenant John Francis Guilmartin, Jr. (AFSN: FR-63863), United States Air Force, for gallantry in action while engaged in military operations involving conflict with an armed hostile force as Pilot of an HH-3C Rescue Helicopter of the 38th Aerospace Rescue and Recovery Squadron, Udorn Royal Thai Air Force Base, Thailand, in action over the Republic of Vietnam on 18 May 1966. On that date, Lieutenant Guilmartin flew his unarmed helicopter into an area infested with anti-aircraft artillery and hostile troops to rescue the two-man crew of a downed F-4B. While attempting the rescue his aircraft was hit by hostile fire, wounding one crewmember. By his gallantry and devotion to duty, Lieutenant Guilmartin has reflected great credit upon himself and upheld the highest traditions of the United States Air Force.
