This work covers how the British devised techniques for fighting guerrillas and terrorists. It shows how traditional policies were supplemented by lessons from World War II, not least the use of special forces, such as the SOE, SIS and SAS. The role of the Special Air Service is covered in detail. The study reveals how key players in the Foreign Office, Colonial Office, War Office, The Cabinet, the Intelligence Services, Colonial Police, RAF and the Army made the advances that produced methods which are used around the globe to this day.
