The SBS was formed out of the Commandos during the Second World War to help counter Nazi domination of Europe. This small unit made up of regulars as well as maverick volunteers took on some of the most dangerous missions of the Second World War. Most famously Operation Frankton, where a small team who became known as the 'Cockleshell Heroes' attacked Axis shipping in Bordeaux harbour. But perhaps their biggest contribution to the war effort came in the run-up to D-Day where SBS reconnoitred the landing beaches in Normandy bringing back vital information that helped shape Operation Overlord and undoubtedly save many lives.

He talks to Dan about how the unit came into operation, the oversized role they played in the war effort and the audacious missions the men of the SBS undertook during the war.
