Special Forces: World's Toughest Test

A new troop of 14 household names face winter warfare training on New Zealand mountains, where the terrain and temperatures are brutal.

Recruits submerge themselves in icy water and then simulate infiltrating enemy infrastructure by racing each other down a 330 foot dam.

The celebrity recruits are put to the test of safely protecting a convoy under a surprise attack.

As a test of their character, they are tasked with a 2-mile race, navigating treacherous terrain, while carrying a 220-pound boat.

Recruits are taken to a mountain range for a demanding exercise: using a single rope to commando cliff crawl across a deadly ravine.

The recruits face a helicopter survival drill, as a test of their ability to mentally handle a life-or-death situation.
