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.
