Survivor executive producer Mark Burnett will try to stretch the limits of reality TV even further with USA Network's Combat Missions, Variety reports. The series will feature current and former members of the U.S. military's elite combat units who will live on a secret base and compete in fictional missions. Burnett, who was once a member of a British parachuting unit, says the 15-episode series will focus both on the action of the urban battlefield and on the personal dramas of the contestants' daily lives.
