SHADOW FORCE on History – Fridays at 10 PM. Operation Ivory Tracker - The team covertly joins forces with a local anti-poaching unit working to save Kenya’s last remaining black rhino from execution by ivory-hungry poachers. With the human and rhino death toll on the rise, the team brings in sophisticated tracking gear that allows them to plan covert tracking equipment into horns and then follow them into the shadows of the black market. It’s an operation that is making every criminal poacher in Kenya nervous as hell. Tune in on Friday November 21st at 10 PM only on History.
