This book Starts with the precursors of the SBS in WWII and traces their early developement, successes and failures in a thorough and entertaining way illustrated by tales of key characters (including, later in the story, Paddy Ashdown). It documents the parallel evolution of other UK special forces like the SAS (better known these days, but the SBS was there first and has always kept a lower public profile), including the operating differences and tensions between them, and the periods when they drifted in and out of favour - a pattern that continued up until the recent gulf wars. A real tale of heroes, or more accurately, superheroes!
