Army veteran and wounded warrior Marc Dervaes is now a top Paralympic snowboarder

For 18 years, Marc Dervaes was a U.S. Army infantryman. He did three tours in Iraq and Afghanistan and lost his arm to an RPG attack on his final combat tour. But Dervaes hasn't let the injury slow him down. Now he's one of the country's best Paralympic snowboarders.
