Three Americans honored as heroes in France for thwarting a suspected terrorist on a train last Friday.

FOX News Radio's Simon Owen reports:

The French President Francois Hollande saying the men prevented carnage after overpowering a gunman as he walked through the train with an assault rifle.

They've been awarded France's highest honor, the Legion of Honor.

They are two U.S. servicemen -- Spencer Stone and Alek Skarlatos -- plus, their friend Anthony Sadler and a British man, Chris Norman:

(Norman) "You know, I think it's something that we really need to think about as citizens, when something like this happens, what are you gonna do?"

Norman saying say he couldn't have done nothing.
