Close-quarters battle, often called close-quarters combat or CQC, is a specific type of combat. It involves multiple combatants fighting at a very short range. This fighting can involve ranged weapons, like firearms, or melee weapons, which are weapons used for close contact.

CQB is defined by its high intensity and short duration. It usually involves sudden violence in confined spaces like rooms or hallways. This type of combat occurs in many settings, including military operations, law enforcement actions, and criminal encounters.

The mechanism of CQB relies on speed and precision within small environments. Combatants must move through structures, such as buildings, while managing threats in multiple directions. In military settings, this might involve breaching a door to enter a room. In law enforcement, the goal is often to secure a location while managing risks to others. The intensity of the situation requires rapid decision-making. Because the distance between people is so small, there is very little time to react to a threat. This makes the training for these situations extremely specialized.

There are different types of CQB depending on who is fighting. Military units use it for various missions. Some units perform peacekeeping or riot control during military operations other than war (MOOTW). Naval boarding teams might adapt these tactics to fight inside the narrow corridors of a ship. Police tactical units, or PTUs, use CQB in domestic settings. These units handle situations that go beyond the normal capabilities of regular police officers.

Private security and private military companies also maintain units trained in these methods. They may protect high-profile individuals or secure government facilities in dangerous areas.

History shows that close combat has existed since the beginning of warfare. In ancient times, people used swords and shields. Later, they used slings, bows, and muskets at close range. During World War I, the narrow spaces of trenches made close combat a major part of warfare. Modern CQB began to take shape through the work of William E. Fairbairn. He was an assistant commissioner for the Shanghai Municipal Police. After 1925, he created a special squad for aggressive policing and riot control.

Fairbairn developed a martial art called "defendu." This method combined different fighting styles to be effective and easy for recruits to learn. It included firearm techniques and the use of everyday objects like chairs or table legs.

During World War II, Fairbairn's methods became essential for Allied special forces. He created a version called the "Silent Killing Close Quarters Combat method" for military use. He also wrote a textbook titled *Get Tough*. Other leaders, such as Rex Applegate and Anthony Biddle, studied his methods in Scotland. Applegate later published *Kill or Get Killed* in 1943. Many famous groups received this training, including the British Commandos, U.S. Army Rangers, and Marine Raiders. Over time, other martial arts like Krav Maga, Sambo, and Capap were also introduced into combat training.

Modern firearm-based CQB tactics emerged in the 1970s. This change followed the 1972 Munich massacre. Western counterterrorist units, such as the Special Air Service (SAS) and Delta Force, developed new ways to assault buildings. Their goal was to be quick and precise to minimize casualties to hostages and friendly forces.

These tactics were shared among closely-knit special forces units. By the 1980s and 1990s, these methods reached police SWAT teams. For a long time, regular infantry did not use these tactics, as they were seen as specialized hostage rescue tools. However, urban wars in the 1990s changed this perception. Battles in Mogadishu, Bosnia, and Chechnya showed the need for better urban combat skills.

The importance of proper CQB training was highlighted during the Iraq War. In the battles for Fallujah, U.S. Marines faced challenges in clearing buildings. They lacked specific CQB training and equipment, which led to many civilian and allied casualties. This made proper urban warfare tactics a priority for infantry. Today, CQB is a major part of military and police training. While some special forces units prefer to keep these tactics exclusive, the complexity of modern cities makes these skills necessary for many different types of soldiers and officers.
