Training for 25 potential Royal Marines Mountain and Arctic Warfare Cadre begins.
Living off the land isn't as easy as it looks, so a bit of scavenging helps.
Five days into a survival course on the Hebrides, and still no food.
Death is just part of the job, so don't hesitate if the enemy comes into sight.
'Direct action' - break into a fort and plant high explosives on a radio mast.
The final stage of training - a 200 mile yomp through the snow - easy!
The trainees complete their recruitment course and discover if they have passed.
