Royal Marines Commando School - Season 1, Episode 05: Phase Two

As training progresses, exercises start to imitate life at war, and the nature of the job begins to worry some of the recruits of Troop 174. University graduate recruit Greene's initially impressive performances are rewarded with a section leadership role, but he is yet to tackle one of training's biggest challenges: the Bottom Field assault course - a set of seemingly-impossible obstacles, tackled while carrying heavy loads of kit. As the Bottom Field test moves closer, problems pile up and Greene's chances of passing look remote. Added to this the troop has a new boss, Captain Simon Smith, who is under pressure to guide Greene and the rest of his troop through this challenging time with as many of them as possible still on track for the Green Beret.
