The President of the United States of America, in the name of Congress, takes pride in presenting the Medal of Honor (Posthumously) to Specialist Fourth Class Thomas Joseph McMahon (ASN: 52895360), United States Army, for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as an Aid Man with Company A, 2d Battalion, 1st Infantry Regiment, 196th Infantry Brigade, Americal Division, in action against enemy aggressor forces at Quang Tin Province, Republic of Vietnam, on 18 March 1969. When the lead elements of his company came under heavy fire from well-fortified enemy positions, three soldiers fell seriously wounded. Specialist Fourth Class McMahon, with complete disregard for his safety, left his covered position and ran through intense enemy fire to the side of one of the wounded, administered first aid and then carried him to safety. He returned through the hail of fire to the side of a second wounded man. Although painfully wounded by an exploding mortar round while returning the wounded man to a secure position, Specialist Fourth Class McMahon refused medical attention and heroically ran back through the heavy enemy fire toward his remaining wounded comrade. He fell mortally wounded before he could rescue the last man. Specialist Fourth Class McMahon’s undaunted concern for the welfare of his comrades at the cost of his life are in keeping with the highest traditions of the military service and reflect great credit on himself, his unit, and the United States Army.
