Sun Tzu is a honorific title bestowed upon Sūn Wu (c. 544-496 BC), the author of The Art of War, an immensely influential ancient Chinese book on military strategy.

He is also one of the earliest realists in international relations theory. In the author's name, Sūn Wu, the character wu, meaning "military", is the same as the character in wu shu, or martial art. Sun Wu also has a courtesy name, Chang Qing (Cháng Qīng).

From the day he was found in a carrier bag on the steps of Guy's Hospital in London, Andy McNab has led an extraordinary life.

As a teenage delinquent, Andy McNab kicked against society. As a young soldier he waged war against the IRA in the streets and fields of South Armagh. As a member of 22 SAS he was at the centre of covert operations for nine years – on five continents. During the Gulf War he commanded Bravo Two Zero, a patrol that, in the words of his commanding officer, 'will remain in regimental history for ever'. Awarded both the Distinguished Conduct Medal (DCM) and Military Medal (MM) during his military career, McNab was the British Army's most highly decorated serving soldier when he finally left the SAS.

Since then Andy McNab has become one of the world's bestselling writers, drawing on his insider knowledge and experience. As well as three nonfiction bestsellers including Bravo Two Zero, the bestselling British work of military history, he is the author of the bestselling Nick Stone and Tom Buckingham thrillers. He has also written a number of books for children.

Besides his writing work, he lectures to security and intelligence agencies in both the USA and UK, works in the film industry advising Hollywood on everything from covert procedure to training civilian actors to act like soldiers and he continues to be a spokesperson and fundraiser for both military and literacy charities.
