Watch Hardcore Heroes

Fire and water are the most deadly of nature's vital elements, especially when unbridled. Hardcore Heroes Jack Pritchard, a FDNY fire-fighting legend, and John Keller, a former recon Marine, come face to face with these ferocious elements.

There are fair fights, unfair fights, and fights where the odds are so stacked against you that you should be obliterated. For two battlefield legends, Drew Dix and Viktor Leonov retreating from a superior army never occurs to them.

In the death-defying tales of valor, there are the heroes who work with others to save lives. Then there are the hardcore heroes who operate as lone masterminds - and get the job done. Carlos Hathcock and Max Hardberger know how to get the job done.

Flying fearlessly into battle is some of the greatest hardcore heroes' second nature. When Kenneth Taylor and George Welch wake up to the Pearl Harbor Japanese Attack, they fight from the sky. And Chuck Yeager is an ace fighter pilot.
