This taut military drama returns for its fourth season, which opens with "God of War," the first of a two-part premiere. As the action resumes, Bravo Team braves enemy territory in the snowy Spin Ghar Mountain Range to pursue and capture a terrorist leader who also is the son of a deadly foe Jason (David Boreanaz) took down early in his career. Under enemy fire, Jason and the team's canine member get separated from the rest of Bravo Team. Bailey Chase and Parisa Fakhri guest star.
