Richard Marcinko is a living, breathing hero – he was honoured with the silver star and four bronze stars for valour, along with two Navy Commendation medals. After serving in Vietnam, he started and commanded SEAL Team 6, the Navy's anti-terrorist group, and Red Cell, a high-level anti-terrorist unit whose exploits, fictionalised for security and legal reasons, have formed the basis of his novels. Jim DeFelice is the author of many military based thriller novels and is a frequent collaborator with Stephen Coonts, Larry Bond, and Richard Marcinko, among other New York Times bestselling authors.
