Close Quarters Battle (CQB) refers to combat that occurs in confined spaces, such as buildings, tunnels, or urban environments. This type of fighting emphasizes quick, decisive actions and often involves small teams of soldiers or law enforcement personnel. CQB techniques are designed to neutralize threats while minimizing risks to civilians and team members. Training for CQB includes skills like room clearing, hand-to-hand combat, and the use of firearms in tight spaces. Specialized units, such as SWAT teams and military special forces, often undergo rigorous CQB training to prepare for high-stakes situations where speed and precision are critical.
