Survival

The directing staff have to whittle the group down to six from 11 and have a surprising trick up their sleeve that they think will cause some participants to instantly withdraw before the final stage.

Those who make it through the cull are faced with their biggest challenge so far - an escape and evasion mission designed to prepare recruits for avoiding capture behind enemy lines. They are divided into two teams and dropped off at dusk, having to cover miles of rough terrain overnight in order to hit their first rendezvous point in nine hours.
