Ultimate Soldier Challenge

They are the best-trained, most-skilled military groups in America. Smart, versatile and agile, they can swiftly adapt to any challenge. These are the men and women of Special Operations, who have always prided themselves on being the best of the best. The Army Rangers trace their origins back to George Washington and the American Revolution, WWII spawned the Navy Seals when the US needed covert amphibious troops, and the Cold War launched the Green Berets. Ultimate Soldier Challenge matches US Special Op units against the most elite forces from around the world in a head-to-head competition that's a showdown of strength, smarts, and strategy. Each episode will feature two, two-person teams who will compete against each other for points through five challenges, with a winner crowned at the end of the show. (History Channel)
