Close-quarters battle (CQB), also called close-quarters combat (CQC), is a close combat situation between multiple combatants involving ranged (typically firearm-based) or melee combat. It can occur between military units, law enforcement and criminal elements, and in other similar situations. CQB is typically defined as a short duration, high intensity conflict characterized by sudden violence at close range.

History

Close-quarters battle has occurred since the beginning of warfare, in the form of melee combat, the use of ranged weaponry (such as slings, bows, and muskets) at close range, and the necessity of bayonets. During World War I, CQB was a significant part of trench warfare, where enemy soldiers would fight in close and narrow quarters in attempts to capture trenches.

The origins of modern close-quarters battle lie in the combat methods pioneered by Assistant Commissioner William E. Fairbairn of the Shanghai Municipal Police, the police force of the Shanghai International Settlement (1854–1943). After the 1925 May Thirtieth Movement, Fairbairn was tasked with developing a dedicated auxiliary squad for riot control and aggressive policing. After absorbing the most appropriate elements from a variety of martial arts experts, Fairbairn condensed these arts into a martial art he called "defendu". The aim of defendu was to be as brutally effective as possible, while also being relatively easy for recruits and trainees to learn compared to other martial arts. 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.

During World War II, Fairbairn was recruited to train Allied special forces in defendu. During this period, he expanded defendu's lethality for military purposes, calling it the "Silent Killing Close Quarters Combat method"; this became standard combat training for British special forces. He also published a textbook for CQB training called Get Tough. U.S. Army officers Rex Applegate and Anthony Biddle were taught Fairbairn's methods at a training facility in Scotland, and adopted the program for the training of Allied operatives at Camp X in Ontario, Canada. Applegate published his work in 1943, called Kill or Get Killed. 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.

For a lengthy period following World War II, urban warfare and CQB had barely changed in infantry tactics. Modern firearm CQB tactics were developed in the 1970s as "close-quarters battle" by Western counterterrorist special forces units following the 1972 Munich massacre. The units trained in the aftermath of the massacre, such as the Special Air Service, Delta Force, GSG 9, GIGN, and Joint Task Force 2, developed CQB tactics involving firearms to quickly and precisely assault structures while minimizing friendly and hostage casualties; these CQB tactics were shared between these special forces units, who were closely-knit and frequently trained together.

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.

Police and law enforcement

Police tactical units (PTU) are the primary units that engage in CQB domestically. Situations involving the potential for CQB generally involve threats outside of conventional police capabilities, and thus PTUs are trained, equipped, and organized to handle these situations. Additionally, police action is often within what can be considered "close quarters", so members of PTUs are often well-trained in or already experienced with CQB, to the point that some PTUs may train military service members in CQB principles such as breaching and room clearing.

Police CQB doctrine is often specialized by unit type and mission. Depending on the unit or agency's jurisdiction or scope, PTUs may have different goals with different tactics and technology; for example, prison guards may maintain a unit trained in CQB in compact indoors areas such as cells without using lethal force, while a police anti-gang unit may be trained in CQB against multiple enemies that may be difficult to identify.

They may be equipped with less-lethal weaponry such as tasers, pepper spray, and riot guns to fire tear gas, rubber bullets, plastic bullets, or beanbag rounds.

Private industry

Private security and private military companies may maintain units that are trained in CQB. 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. For instance, the U.S. Department of State employed such security teams in Iraq.

Private military and security companies known to maintain units that are trained in, or are capable of training other units in, CQB include Blackwater and SCG International Risk.
