Selection for the SAS is one of the world's toughest job interviews and physical fitness is only the starting point. What's really being tested is psychological resilience and character as candidates undergo sleep deprivation, interrogation and a series of increasingly complex mind games. In this programme, five ex-special forces soldiers re-create tasks from the SAS's secret selection process, putting 30 civilian men through the ultimate test of their physical and - more importantly - their psychological resilience.
The recruits' first task is an unexpected one: writing an essay about themselves. Then they face an eight-mile combat fitness test while their essays are dissected for an insight into their character.
The remaining recruits must choose their weakest colleagues, who then lead the next exercise. And there's the 'Sickener': a series of physical challenges that won't end until five recruits give up.

The reality show returns with its toughest training course yet, against the backdrop of the Jordanian desert. The initial 21 recruits are sent on an intense journey to their base through searing heat. Once they have made it back to safety, their ability to work as a team is tested when they cross a ravine by balancing on a rope suspended 165 above the ground.
All 20 trainees have made it through to the second stage - where they must make a split-second decision about whether or not to fire in a combat situation. They also face a brutal training session in the desert that pushes some of them to the edge, and must freefall off the top of a 50-foot cliff, trusting a teammate to catch them. This episode also deals with overcoming family tragedy and childhood adversity.
The recruits put their hand-to-hand combat skills to the test, while an elimination test on a 400 metre sand dune proves to be the final straw for four of the recruits. Among the other challenges they will face during a gruelling 48 hours are a seven-metre backwards dive and a simulated ambush while driving.
The eighth series of the reality show takes its inspiration from the jungle phase of SAS selection, which is notoriously the most gruelling phase of the SAS' training regime. The first episode sees the 20 candidates challenged to control their fear with an exercise carried out 50 feet above the ground, before facing one of the most dangerous infiltration methods used by the SAS - a waterfall abseil.
A recruit becomes stranded at the top of a 215-foot waterfall, ending up pinned to the rocks and terrified of drowning. The incident reminds instructor Billy Billingham of situations when he as lost fellow operatives on similar missions. Later, a breach of camp discipline is punished with a relentless series of extreme physical tasks, followed by intensive hand-to-hand combat training sessions.
The group members are tasked with an energy-sapping uphill hike, before being confronted with a 200ft abseil into a dark bat-infested cave. Later in a bustling civilian market, the recruits must track down an armed gunman on the loose among innocent civilians. Will they be able to locate the target and take them down?
