He served in B Squadron 22 SAS for ten years and worked on both covert and overt special operations worldwide, including anti-terrorist and anti-drug operations in the Middle and Far East, South and Central America and Northern Ireland. Trained as a specialist in counter terrorism, prime target elimination, demolitions, weapons and tactics, covert surveillance and information gathering in hostile environments, and VIP protection, McNab worked on cooperative operations with police forces, prison services, anti-drug forces and western backed guerrilla movements as well as on conventional special operations.

McNab also worked as an instructor on the SAS selection and training team and instructed foreign special forces in counter terrorism, hostage rescue and survival training. Andy McNab has written about his experiences in the SAS in two bestselling books, Bravo Two Zero (1993) and Immediate Action (1995).

The BBC's film of Bravo Two Zero, starring Sean Bean, was shown on primetime BBC 1 television in 1999 and released on DVD in 2000. Immediate Action, McNab's autobiography, spent 18 weeks at the top of the bestseller lists following the lifting on an ex-parte injunction granted to the Ministry of Defence in September 1995. To date, Immediate Action has now sold over 1.4 million copies in the UK. McNab is the author of seven fast action thrillers, highly acclaimed for their authenticity and all Sunday Times bestsellers.
