Sri Lanka went through a two-decade long civil war that saw the country plunged into chaos. In 1996, a new Special Forces unit was formed to try and bring the conflict to an end. This top-secret group went on to play a huge role, operating deep behind enemy lines, gathering intelligence and eliminating key targets. Until now, no one has ever filmed this elite unit, and until the end of the war, the government kept their very existence under wraps. History Channel gets exclusive access behind the scenes and uncovers the training of Sri Lanka's Long Range Patrol unit of the Special Forces Brigade. Selected from the very elite of the Special Forces unit, they embark on a grueling 6-month training program. It all starts with three weeks of relentless physical and psychological torture that will push them to their absolute limits and break all but the best. -Written by Infocus Asia
