In the first episode the 30 recruits arrive at the isolated barracks in Wales and are introduced to the directing staff (DS) Foxy, Ollie and Colin, all operating under the watchful eye of Chief Instructor Ant. This is an elite team: four ex-Special Forces men with years of military and Special Forces experience, including dozens of tours of Afghanistan, Northern Ireland, Iraq and Sierra Leone. They have all experienced, at first hand, the strength, mental resilience and raw determination needed to pass Selection.
