Technical Sergeant Lewis J. Roberts, Jr. distinguished himself by heroism as Pararescue crewmember over the Republic of Vietnam on 2 March 1965.  One that date, Sergeant Roberts and crew were tasked with an extremely hazardous night search and rescue mission for an American pilot who had bailed out of his battle damaged aircraft deep within hostile territory.  Completely ignoring numerous dangers, which made continuation of the mission impractical from the standpoint of their own safety, Sergeant Roberts and crew doggedly persevered in a two-hour search conducted at low level and without fighter cover although in close proximity to anti-aircraft gun emplacements.  Their efforts were rewarded when they finally located and identified the downed airman and then directed other rescue forces, who had belatedly arrived over the scene, in making a successful recovery.  The outstanding heroism and selfless devotion to duty displayed by Sergeant Roberts reflect great credit upon himself and the United States Air Force.
