The commandos have become a byword for elite raiding and cutting-edge military operations. They were set up during the Second World War in June 1940, following a request from Winston Churchill, for special forces that could carry out raids against German-occupied Europe. As Monty Halls says, they were 'well trained men who wreaked havoc'. But to be the best you have to train the hardest and where better and more challenging than the wild and rugged highlands of Lochaber, Scotland.

In today's episode Dan takes the podcast to Achnacarry Castle, the Clan Cameron headquarters turned Commando Basic Training Centre during World War Two. Both clan chief Lochiel Donald Cameron and ex-Royal Marine Monty Halls tell Dan about the gruelling initiation hike, the assault courses with live ammunition and the harsh weather that made the Commandos the best of the best.
