The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Flying Cross to Major Robert Michael Greene (AFSN: 0-29087A), United States Air Force, for extraordinary achievement while participating in aerial flight as an F-100 Forward Air Controller operating over North Vietnam on 29 January 1968. On that date, while operating under low ceilings in a heavily defended area of North Vietnam, Major Greene located several camouflaged rail cars and a large concentration of watercraft loading supplies. Ignoring heavy anti-aircraft artillery fire, Major Greene repeatedly marked targets for the strike aircraft, thereby neutralizing the hostile re-supply efforts in this strategic area. The professional competence, aerial skill, and devotion to duty displayed by Major Greene reflect great credit upon himself and the United States Air Force.
