The 25-year history of a top-secret US Army special operations unit. ‘The Activity’, as it became known to insiders, has hidden behind a myriad of code-names like Gray Fox and Torn Victor. It has been publicly ‘disbanded’ and then secretly resurrected so often that it has near mythical status, even among the world's special operations elite. Michael Smith has spoken to many former members of ‘The Activity’ and we follow them on operations from the undercover ops in Beirut in the 1980s to the capture of Saddam Hussein and the assassination of key members of al Qa'eda. They were also active in South America, spearheading the war on the drug barons and providing the electronic surveillance that led Colombian ‘death squads’ to the hideouts of Pablo Escobar and his men. Killer Elite reveals the truth behind the world’s most secret Special Operations organisation: a unit that is at the forefront of the war on terror.
