Heres a unoffical paragraph about the OC od the SAS
Colonel Sir David Stirling, OBE, DSO
David Stirling was a restless young officer. He had been educated at Ampleforth College, Newmarket Racecourse, White's Club, but mostly enjoyed his time at Cambridge University. When WWII broke out, Stirling joined up. He served in Scots Guards, No. 8 Commando, Layforce. The unit was soon disbanded but Stirling never lost site in his training. He took up Parachuting (which was rare) and soon began to invision a small unit that could strike fast.
In 1941, David Stirling was injured in a parachute accident. He was bed ridden in Cario, Egypt. While laying in bed, the young officer came up with the idea of a small unit to strike the enemy fast. Using his knowledge of Commando operations, he decided to come up with a new unit. The Commandos had operated in large numbers. Stirling wanted a unit that would operate in 4-5 man teams. Still on crutches he went to propose the idea to senior officers. The guards stopped Stirling and turned him away (this happened a second time as well). Stirling simply walked around to the side of the chain fence and jumped over. Once inside the Senior Officers were so impressed with Stirling they listened to his ideas.
Stirling called his new unit L Detachment Special Air Service. The SAS was born working along side of the LRDG (Long Range Desert Group). The groups mounted raids against German targets with great success. Stirling was captured in 1943. Although Hitler had made it known that any Special Forces soldiers captured were to be executed (and many had been), Stirling never let on who he was. He did what every soldiers feels is his duty when caught, he tried to escape. In fact he did escape four times, but was caught each time. Finally he was placed in Colditz. He was later released after the war.
Stirling has been said to be the "most under-decorated soldier of the war". This is very true, as the "Phatom Major" was responsible for making the SAS what it is today. He was knighted in 1990, but unfortunately died only months later at his home in Scotland.
