That was Sgt. Jay Levitow, a "Puff" crewchief, the USAF's only enlisted MoH. I used to work with him in Hartford. Passed away a few years back.
There is a second enlisted Medal of Honor winner from Viet Nam. Originally, he was awarded the AF Cross but recently it was upgraded to the Medal of Honor. His name was William H. Pitsenbarger. Here is his citation.
The President of the United States of America, authorized by Act of Congress, March 3, 1863, has awarded in the name of The Congress the Medal of Honor to
AIRMAN FIRST CLASS WILLIAM H. PITSENBARGER
UNITED STATES AIR FORCE
For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty. Airman First Class Pitsenbarger distinguished himself by extreme valor on 11 April 1966 near Cam My, Republic of Vietnam, while assigned as a Pararescue Crew Member, Detachment 6, 38th Aerospace Rescue and Recovery Squadron. On that date, Airman Pitsenbarger was aboard a rescue helicopter responding to a call for evacuation of casualties incurred in an ongoing firefight between elements of the United States Army's 1st Infantry Division and a sizeable enemy force approximately 35 miles east of Saigon. With complete disregard for personal safety, Airman Pitsenbarger volunteered to ride a hoist more than one hundred feet through the jungle, to the ground. On the ground, he organized and coordinated rescue efforts, cared for the wounded, prepared casualties for evacuation, and insured that the recovery operation continued in a smooth and orderly fashion. Through his personal efforts, the evacuation of the wounded was greatly expedited. As each of the nine casualties evacuated that day was recovered, Airman Pitsenbarger refused evacuation in order to get more wounded soldiers to safety. After several pick-ups, one of the two rescue helicopters involved in the evacuation was struck by heavy enemy ground fire and was forced to leave the scene for an emergency landing. Airman Pitsenbarger stayed behind on the ground to perform medical duties. Shortly thereafter, the area came under sniper and mortar fire. During a subsequent attempt to evacuate the site, American forces came under heavy assault by a large Viet Cong force. When the enemy launched the assault, the evacuation was called off and Airman Pitsenbarger took up arms with the besieged infantrymen. He courageously resisted the enemy, braving intense gunfire to gather and distribute vital ammunition to American defenders. As the battle raged on, he repeatedly exposed himself to enemy fire to care for the wounded, pull them out of the line of fire, and return fire whenever he could, during which time he was wounded three times. Despite his wounds, he valiantly fought on, simultaneously treating as many wounded as possible. In the vicious fighting that followed, the American forces suffered 80 percent casualties as their perimeter was breached, and Airman Pitsenbarger was fatally wounded. Airman Pitsenbarger exposed himself to almost certain death by staying on the ground, and perished while saving the lives of wounded infantrymen. His bravery and determination exemplify the highest professional standards and traditions of military service and reflect great credit upon himself, his unit, and the United States Air Force.
