Editing Defendu (section)

==Second World War==
The start of the Second World War saw the Allied forces needing every advantage to give their soldiers and [[special forces]] a winning edge. They found one such edge in Fairbairn's system. Immediately, Fairbairn was commissioned in the [[British Commandos]] and ordered to teach a lethal version of his system at the [[Achnacarry Castle|Commando school]] in [[Scotland]].

It was at this top secret Scottish location that Colonel [[Rex Applegate]] of the [[U.S. Army]] studied under Fairbairn. Through Col. Applegate and other instructors such as [[Anthony Joseph Drexel Biddle, Sr.|Col. Anthony Biddle]], these highly effective skills were taught to U.S. troops including [[United States Marine Corps|US Marines]] and [[United States Army Rangers|Rangers]], as well as OSS operatives and later to the [[FBI]] and [[CIA]] as the foundation of their basic training.

Once the British Commando School in Scotland was able to produce its own Fairbairn/Sykes qualified instructors, both men were transferred. Fairbairn to [[North America]], and Sykes to SOE, where he trained special agents for behind the lines duties {{clarify|date=November 2011}}. Fairbairn's 'special assignment' in [[Oshawa]], Ontario, Canada, was to teach his system to Allied special forces at the most highly classified training operation of WWII, [[Camp X]]. Agents were trained in depth to dispose of their enemy quickly and quietly with brutal effectiveness. Following his instruction at Camp X, Fairbairn was rejoined by Col. Applegate to form the United States Camp B, now known as [[Camp David]].

This introduction of 'The Fairbairn Fighting System' at Camp X in conjunction with input from many highly skilled instructors with various backgrounds and fighting skills was the beginning of the evolution of Defendu. As close quarters battle or [[unarmed combat]] training progressed throughout this period, it was added and refined utilising western fighting principles.
