The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Second Bronze Oak Leaf Cluster in lieu of a Third Award of the Distinguished Flying Cross to First Lieutenant (Armor) David L. Porter, United States Army, for heroism while participating in aerial flight evidence by voluntary actions above and beyond the call of duty on 23 January 1970 while serving as a pilot with the Aero Scout platoon, Air Cavalry Troop, 11th Armored Cavalry Regiment, in the Republic of Vietnam. On this date while conducting a visual reconnaissance mission, Lieutenant Porter was notified of an enemy force erecting anti-aircraft positions in the dense jungle northeast of Loc Ninh. He volunteered to search the suspected area for enemy but found it difficult to see due to the triple canopy jungle below so he flew at tree top level and low air speed. As he began receiving intense ground fire, he marked the position with smoke and directed the rocket fire from gunships. After refueling and rearming his craft, he returned to the contact area to make an assessment of the damage and again came under intense anti-aircraft fire. After marking the positions from the gunships, the command and control helicopter assumed control of the contact while directing and adjusting artillery. Due to the heavy cover of smoke and dust it was necessary for Lieutenant Porter to hover over the area at tree top level relaying intelligence information to his gunship. He came under heavy enemy fusillade and returned the fire. First Lieutenant Porter’s 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.
