3. Tim Kennedy
MMA fighters are a special kind of tough but Tim Kennedy takes this to the extreme. The former UFC middleweight contender servedn the National Guard while fighting at the highest level of combat sports. Then he signed up with the US Special Forces in 2004. This forced him to balance his professional fighting career alongside overseas deployment and military duties.

Kennedy left active duty in 2009 before returning to the Green Berets in 2017, where he remains today. The Bronze Star for valor under fire award is one of his proudest accomplishments from his career. Meanwhile, the highlight of his combat sports career was when he headlined the UFC Fight for the Troops event in 2013, where he beat Rafael Natal.
