The history of the modern SAS is one of the great successes of post-war Britain. Since it was revived in 1950 to combat Communist insurgents, the Regiment has gone from strength to strength, fighting covert wars in Oman, Borneo, Northern Ireland, the Falklands, the Persian Gulf and beyond. In the process, it has become one of the most indispensable, and at times controversial, units in the British army. Today, the SAS is regarded as the world's leading Special Forces unit, renowned for its demanding Selection course and its relentless ability to adapt to the changing nature of warfare. More than anything else, however, it is the determination and ingenuity of the SAS soldiers that has made the Regiment what it is today. Drawing on his extensive network of contacts and his own experiences, Chris Ryan tells the story of the men on the ground.
