PERTON, England — United States Navy Chief Petty Officers, Michell Jordan and Jesse Harrahill share words of encouragement during the Tough Guy Challenge near Birmingham, England. The Tough Guy Challenge is the only event of its kind in the world and one of the toughest contests to be undertaken. It consists of a unique blend of mud, freezing lakes, acrophobia, claustrophobia, barbed wire, fire and electro shocks. (Photo by Air Force Staff Sgt. Javier Cruz)
