Andy McNab (Author) As a troubled teenager, Andy McNab kicked against society. As a young soldier he waged war against the IRA in the streets and fields of Northern Ireland. As a member of 22 SAS he was at the centre of secret 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.www.andymcnab.co.ukKevin Dutton (Author) Dr Kevin Dutton is a research psychologist at the Department of Experimental Psychology, University of Oxford.
