Rusty Firmin

Rusty Firmin's third book will be a direct follow on from The Regiment: 15 Years in the SAS. That's when Rusty finished his service after 27 years in 1992, having served since the age of 15.

The book will tell of what happens when a highly motivated man leaves the SAS and takes up civil employment on the private security industry circuit.

The good times, the bad times, humour, excitement and camaraderie - it will all be covered.
