Colin Armstrong MM (born 1961), usually known by the pseudonym and pen-name of Chris Ryan, is an author, television presenter, security consultant and former Special Air Service sergeant. After the publication of fellow patrol member Andy McNab's Bravo Two Zero in 1993, Ryan published his own account of his experiences during the Bravo Two Zero mission in 1995, entitled The One That Got Away. While this has led to a very successful career in writing, both his and McNab's accounts of the Bravo Two Zero mission have been heavily criticised by their fellow patrol members and questioned by other SAS members about their authenticity.[citation needed] Since retiring from the British Army Ryan has published several fiction and non-fiction books, including Strike Back, which was subsequently adapted into a television series for Sky 1, and co-created the ITV action series Ultimate Force. He has also presented or appeared in numerous television documentaries connected to the military or law enforcement.
