 I am Army Sergeant Abigail Waldrop. It's an unusually bright and sunny day here in London for the 2012 Paralympic Games, and today a different kind of football season is gearing up. A couple of players on the U.S. men's seven-aside football team are trading their combat boots for cleats. Two wounded warriors are still proudly serving their country on the football pitch. Oh yeah, it's a lot of fun, it's a lot of, obviously there's a lot of pride in it, but it's a different experience. It's surreal right now. Marine Corporal Rene Renateria and retired Army Staff Sergeant Gavin Sibion are rebounding from combat-related injuries and setting new goals. They still have another game to bounce back, but regardless, both U.S. military players have had the experience of a lifetime. Reporting from the 2012 Paralympic Games, I'm Army Sergeant Abigail Waldrop.
