At Close Quarters: SOE Close Combat Pistol Instructor Colonel Hector Grant-Taylor

 David Armstrong works as a freelance security consultant and investigator. It is during this career that he studied what is known as the "Grant-Taylor shooting method." Five years ago he began by researching who Grant-Taylor was, and as of now, is the only person who has managed to gather together all the pieces of his life accurately and present it in a comprehensive work.
