Fairbairn served with the
Royal Marine Light Infantry starting in 1901, and joined the
Shanghai Municipal Police (SMP) in 1907. He served in one of the
red light districts. During his service with the International Police in Shanghai, Fairbairn reportedly engaged in hundreds of street fights in the course of his duties during a twenty-year career. Much of his body, arms, legs, torso, even the palms of his hands, were covered with scars from knife wounds from those fights. Fairbairn later created, organised, trained and commanded a special
anti-riot squad for the Shanghai police force. He also developed numerous firearms training courses and items of police equipment, including a special metal-lined
bulletproof vest designed to stop high-velocity bullets from the
7.63x25mm Mauser pistol. He trained British, American and
Canadian Commandos and
No. 2 Dutch Troop 10th Inter-Allied Commando forces,
US Rangers candidates, and personnel of the
Office of Strategic Services (OSS), mainly for close-combat, pistol-shooting and knife-fighting techniques. Fairbairn emphasised the necessity of forgetting any idea of gentlemanly conduct or fighting fair: "Get tough, get down in the gutter, win at all costs... I teach what is called 'Gutter Fighting.' There's no fair play, no rules except one:
kill or be killed," he declared. One of his pupils was
Raymond Westerling, who fought behind enemy lines in
Burma and
Indonesia. In 1941, he appeared in a training movie titled "Unarmed Combat", demonstrating many of the strikes, holds and throws of Defendu, for use by the Home Guard, Commandos, and military services. This training movie was narrated by actor
David Niven, who had joined the Commandos early in the war, and was trained by Fairbairn himself. In 1942, Fairbairn appeared, again uncredited, in an OSS training movie titled "OSS Training Center", directed by
John Ford. Fairbairn again demonstrated unarmed combat, and also his version of "
Point Shooting", later adopted and refined by Rex Applegate for use by the U.S. Army. For his achievements in training OSS personnel, Fairbairn was promoted eventually to the rank of
Lieutenant-Colonel by the end of the war, and received the U.S.
Legion of Merit (Officer grade) at the specific request of OSS-founder
"Wild Bill" Donovan. ==Martial arts==
