Wounded U.S. service members participate in the 100m sprint during the 2015 Department of Defense Warrior Games at Marine Corps Base Quantico, Va., on June 23, 2015.

I had the privilege of attending the 2011 Warrior Games in Colorado Springs with the USO. It was a once in a lifetime experience that I will never forget. As I wrote at the time, the dedication and courage on display at the annual event is uniquely inspirational. Like no other sporting event, every single competitor at the Warrior Games has overcome unimaginable odds to compete with their fellow heroes.

Congratulations to all participants in the 2015 Warrior Games. Most importantly, we thank these brave men and women for sacrificing so much to defend our freedom.
