Close-quarters battle
[citation needed] After the 1925 May Thirtieth Movement, Fairbairn was tasked with developing a dedicated auxiliary squad for riot control and aggressive policing.
The method incorporated both less-lethal and lethal fighting tactics, such as point shooting, firearm combat techniques, and the use of more ad hoc weapons such as chairs or table legs.
[4] During the war, training was provided to British Commandos, the First Special Service Force, OSS operatives, U.S. Army Rangers, and Marine Raiders.
Other military martial arts were later introduced elsewhere, including European Unifight, Chinese sanshou, Soviet sambo, and the Israeli kapap and Krav Maga.
Specialized forces may adapt MOUT tactics to their own needs, such as marine naval boarding teams being trained specifically to search ships and fight CQB within them.
Hostage rescue or extraction units may involve even more esoteric adaptations or variations, depending on environments, weapons technology, political considerations, or personnel.
[6] Armies that often engage in urban warfare operations may train most of their infantry in basic CQB doctrine as it relates to common tasks such as building entry, clearing a room, and using different types of grenades.
Unlike their military counterparts, PTUs, as law enforcement officers, are tasked with ideally apprehending suspects alive; for this reason, they are often trained in arrest procedures, non-lethal takedowns, and standoff negotiation instead of solely combat.
These teams may be responsible for responding to an incident at a facility operated by a government agency that has hired their security services, or to provide protection for VIPs in combat zones.
