The British Special Air Service regiment, the SAS, is one of the world’s most elite and secretive military organisations. It’s the story of how and where the SAS began. It’s the story of one man: David Stirling. And the band of misfits and rule-breakers who were with him on Day One: The Originals. Effectively, it’s the story of the birth of modern Special Forces. SAS: The Originals is that story.
