Whether it is one of their own, or a civilian caught in the chaos of war, combat rescue is one of the most important--and dangerous--roles at which the Navy SEALs excel.

The Navy SEALs pursue America’s enemies all across the globe, hunting down the worst of the worst and bringing them to justice. Working together with U.S. intelligence agencies, as well as conventional forces and coalition allies, the SEALs are unmatched in their abilities to find, to fix and to finish the enemy.

Extreme training and combat expertise are only part of what make the SEALs the world's most effective fighting force. What truly sets them apart is their warrior ethos: a code of honor combining courage, discipline, and unhesitating willingness to risk life and limb to accomplish the mission or aid a fallen fellow soldier.

Part 1 takes us through the incredible history of the SEAL's predecessors in WWII and Korea--the underwater demolition teams that helped secure the beaches of Normandy and the Pacific--through their evolution into elite warriors, fighting in the jungles of Vietnam, the formation of SEAL Team 6, executing secret missions in Panama and Grenada, all the way up to 9-11-- the event that will change the way America fights wars.
