“The end product of CQB training must be automatic and instantaneous killing.”

“CQB” — Just hearing that brings memories of hours on the range practicing everything from basic individual marksmanship to room and building entry dynamics with teams. One can’t forget the martial arts learned in the dank cellars and isolated training areas of a remote forest. Close Quarter Battle is one of those monikers that gets tossed about like a salad. Everyone has their own version, which is a cautionary tale because not all versions work.

The principal pioneer of CQB is, of course, William Ewart Fairbairn. A former Royal Marine and British colonial policeman in China, Fairbairn joined the Shanghai Municipal Police (SMP) in 1907. The SMP was established to police the Shanghai International Settlement in China and was manned by Japanese, British, American, Russian, Sikh, and Chinese volunteers. Fairbairn was both a street cop and a trainer—he observed police and criminal tactics to develop better operational procedures. Fairbairn created the SMP Reserve Unit (RU), essentially the first Special Weapons and Tactics unit in the world. The RU officers were trained in what Fairbairn called ‘Gutter Fighting’ — that is, how to take down the hardest criminals of the Triad gangs and their ‘Hatchet-men’ when no backup was to be expected.

Fairbairn learned his ‘tactics, techniques, and procedures’ the hard way — on the streets. After one nasty encounter and a lengthy medical recovery, he learned Judo from a Japanese instructor. Then he picked up various Chinese systems and, incorporating all that was good in each, he developed his own fighting system called “Defendu.” It was a complete system of armed and unarmed methodologies that he taught to the SMP and reportedly to the 4th Marines, the “China Marines,” a 1,000-man regiment that served in Shanghai’s International Settlement before World War II. Fairbairn’s cohort and co-designer of the Fairbairn-Sykes fighting knife, Eric Anthony Sykes, the chief of the RU’s sniper section, was at his side and co-developed many of their CQB techniques during their time together in China.

Fairbairn returned to England at the onset of WWII and was recruited, along with Sykes, to teach CQB to the operatives of the British Special Operations Executive (SOE), the American Office of Strategic Services (OSS), as well as commandos and the Secret Intelligence Service (SIS) also known as MI6. Additionally, he instructed the Home Guard’s secret Auxiliary Units, who would act as stay-behind forces in the event Germany invaded Britain.

Fairbairn was then detailed to SOE Special Training School No. 103, aka “Camp X,” located near Lake Ontario, Canada. There, he trained Commonwealth and American operatives in his “quick and dirty fighting” skills, ranging from unarmed combat and knife fighting to the use of small arms in close quarters. Probably the most important aspect of Fairbairn’s methods was that he sought to instill the mindset to kill an enemy in combat without hesitation. Likewise, Sykes tried to do the same and ended all his demonstrations with the words, “and then, kick him in the testicles.”

Key to Fairbairn’s methodology was “instinctive fire.” Instead of carefully aimed shots at fixed targets, trainees went into a crouched position and quickly squeezed off two rounds — a “double tap.” Kill the enemy before he kills you. With submachine guns, he encouraged trigger control and the same double-tap method rather than full automatic bursts.

One of his training tools was what he called “the fun house,” an innovative shooting facility his students preferred to call “the house of horrors.” First used in Shanghai to train SMP officers. Fairbairn and Sykes built a similar building at SOE’s Lochailort, Scotland training base. Based on a small cottage that incorporated pop-up targets, trainees entered through the roof to engage targets in darkened rooms filled with smoke, disorienting lights, and soundtracks of gunfire and explosions. Fairbairn ensured similar training facilities were built at STS 103 and OSS training sites in the United States. These killing houses have since become standard training fare with special operations forces worldwide.
