Chain of Command

"Chain of Command" is an intimate portrait of what has been dubbed "the war of this generation" -- the U.S. military's mission to combat violent extremism around the world -- and the men and women devoting their lives to it. Filmed over 18 months, the eight-part documentary allows viewers unprecedented access inside the Pentagon to see how decisions made there have a direct impact on service members fighting on the front lines to protect Americans and U.S. allies from radicalized extremists. The series also includes a rare on-camera sit-down with Gen. Joseph Dunford Jr., the chairman of the Joint Chiefs of Staff.
