Immediate Action is an intense account of an extraordinary life, from the day Andy McNab was found in a bag in the foyer of Guy's Hospital to the day he went to fight in the Gulf War. As a delinquent youth, he rebelled against society. As a young soldier, he fought against the IRA on the streets and fields of South Armagh. As a member of the 22 SAS Regiment, he found himself at the center of covert operations for nine years - on five continents.

Retelling his activities in the world of the most trained and effective special forces unit with bitter humor and in gripping, often horrifying detail, McNab introduces us to a world of surveillance and intelligence gathering, counter-terrorism strikes, and hostage rescue. There are casualties: the best men are often the first to be killed, because they are at the front.

Amidst absolute cold description, astonishing incidents, violence, humor, and emotion, this breathtaking true account of life at the front line of combat confirms Andy McNab's place at the top of writers on modern warfare.
