Physical fitness
Exercises were conducted using live ammunition and explosives to make training as realistic as possible. Physical fitness was a prerequisite, with cross country runs and boxing matches to improve fitness. Speed and endurance marches were conducted up and down the nearby mountain ranges and over assault courses that included a zip-line over Loch Arkaig, all while carrying arms and full equipment. Training continued by day and night with river crossings, mountain climbing, weapons training, unarmed combat, map reading, and small boat operations on the syllabus.
