 Following the hill phase is the jungle phase, taking place in Belize, Brunei, or Malaysia. Candidates are taught navigation, patrol formation and movement, and jungle survival skills. Candidates returning to Hereford finish training in battle plans and foreign weapons and take part in combat survival exercises, the final one being the week-long escape and evasion. Candidates are formed into patrols and, carrying nothing more than a tin can filled with survival equipment, are dressed in old Second World War uniforms and told to head for a point by first light. The final selection test is arguably the most gruelling: resistance to interrogation (RTI), lasting for 36 hours.
