Citation... For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. Sp4c. McMahon distinguished himself while serving as medical aid man with Company A. When the lead elements of his company came under heavy fire from well-fortified enemy positions, 3 soldiers fell seriously wounded. Sp4c. McMahon, with complete disregard for his safety, left his covered position and ran through intense enemy fire to the side of 1 of the wounded, administered first aid and then carried him to safety.
