"Britain's SBS - or Special Boat Service - was the world's first maritime special operations unit. Founded in the dark days of 1940, it started as a small and inexperienced outfit that leaned heavily on volunteers' raw courage and boyish enthusiasm. It went on to change the course of the Second World War - and has served as a model for special forces ever since"--Publisher's description.
