Roy Benavidez was a Master Sergeant in 5th Special Forces Group, he was also attached to ARVN Advisory group on his first rotation, and a member of MAC-V SOG on his second rotation.
In 1965, Benavidez was part of an ARVN advisory group in South Vietnam when he stepped on a mine and was evacuated to the US. The doctors in the hospital told the MSG that he would never walk again. Benavidez proved them wrong by getting out of bed every night, crawling on his elbows and chin, and propped himself unaided. Wiggling his toes, then his feet to the point of tears. After months of excruciating pain and self-motivation, Benavidez walked out of the hospital and returned to Vietnam.
