Season 3 - Episode Guide

The Namibian desert is the hostile setting as 24 volunteers subject themselves to weeks of Special Forces training at the hands of battle-hardened Staff Sergeant Eddie Stone. Dermot O'Leary presents the gruelling action as the volunteers embark on their first assignment- a debilitating route march through the searing heat of the desert. 

It's day four of the SAS recruits' notoriously tough training, and they must attack an enemy village before Eddie Stone puts them through hell in the endurance test. Dermot O'Leary follows the 21 volunteers' progress.

On the run after ambushing an enemy force, the volunteers must evade capture if they are to avoid a night of extreme interrogation by army personnel. 

The volunteers launch an attack on enemy forces while coming under fire themselves. Then they have to operate in an area filled with land mines, where they must make some difficult decisions about resultant casualties. 

Are the civilians starting to think like soldiers?

The six remaining volunteers have to capture a terrorist leader who is known to be located in the barren and treacherous Khan River valley.

The final round of punishing tests from the Namibian wilderness sees the four remaining volunteers carry out a solo parachute jump from 11,000ft and raid an enemy camp. Who will be declared "tough enough" to make the grade?
