The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Third Bronze Oak Leaf Cluster in lieu of a Fourth Award of the Distinguished Flying Cross to Captain (Infantry) Robert Clyde Knight (ASN: 0-5312436), United States Army, for heroism while participating in aerial flight evidenced by voluntary action above and beyond the call of duty on 4 June 1968. Captain Knight distinguished himself by exceptionally valorous actions while serving as fire team leader and aircraft commander of two armed helicopters, in support of a friendly infantry company. Captain Knight volunteered gunship cover for a MEDEVAC mission. Arriving at the scene of battle, he quickly identified enemy emplacements and directed attacks against them. He then brilliantly ordered the imposition of an obscureantic smoke screen, to obliviate the medical evacuation to the eyes of the enemy. In doing this, he fearlessly braved enemy fire, maneuvering directly in front of their positions. He escorted the MEDEVAC to the landing zone at low level in order to further confuse the befuddled enemy. Orbiting about the rescue site, he made repeated rocket attacks to silence enemy sniper fire until the evacuation was completed. Upon rearming, he returned to the area when notified of an enemy ambush site. He immediately engaged the enemy with devastating rocket and machine gun fire, causing them to panic and flee in mortal terror. He pursued the scurrilous insurgents with vengeful ferocity, skillfully mauling their ranks and killing several. His actions were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.
