The origins of modern close-quarters battle lie in the combat methods pioneered by Assistant Commissioner

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.

, 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''.

As late as the 1990s, some infantry manuals on urban combat described close-quarters room clearing essentially the same basic way it was described 60 years prior: a grenade being thrown into an enclosed area, followed by an infantry assault with automatic fire.

With similar struggles in towns and cities among
ABCA Armies during the
War in Afghanistan, a proper approach to infantry in urban warfare became crucial, and CQB tactics began to be more widely taught to infantry.
According to scholar Anthony King, some special forces units
express disdain at regular infantry being taught CQB, especially in organizational politics and internal matters such as securing budgets; a unit with CQB training requires expensive equipment and training facilities, using up funding that could be used for other units or purposes.

Pudu Prison siege, the
Special Actions Unit (special ops unit of the Royal Malaysia Police) turned to hand-to-hand combat, using batons and rattan canes, after the Malaysian Prime Minister ordered the resolution of the hostage crisis without the use of firearms. The result was a victory for the police, and the five prisoners holding hostages in Pudu Prison were arrested.
* The
Battle of Danny Boy took place close to the city of Amarah in southern Iraq on 14 May 2004, between British soldiers and about 100 Iraqi insurgents of the Mahdi Army. The insurgents ambushed a patrol of Argyll and Sutherland Highlanders close to a checkpoint known as Danny Boy near Majar al-Kabir. The Argylls called in reinforcements from the 1st Battalion of the Princess of Wales's Royal Regiment; the latter were also ambushed, and due to an electronic communications failure, it was some time before further British relief arrived. While waiting for reinforcements, the British were involved in one of the fiercest engagements they fought in Iraq. The fighting involved close-quarter rifle fire and bayonets. The battle lasted for about three hours, during which 28 Mahdi Army insurgents were killed; the British suffered some wounded, but none were killed in the action.

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.

s (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.
Unlike their military counterparts, PTUs, as law enforcement officers, are tasked with ideally apprehending suspects alive; for this reason, they are often trained in

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
