Close-quarters combat (CQC) refers to physical confrontations that occur at very short distances, typically within arm's reach. This type of combat often involves hand-to-hand techniques, as well as the use of melee weapons like knives or clubs. CQC is commonly used in military and law enforcement situations, where quick and decisive action is necessary in confined spaces. Training for CQC emphasizes speed, agility, and situational awareness. Practitioners learn various techniques, including grappling, striking, and weapon disarming. CQC is essential for personnel in military operations, SWAT teams, and self-defense scenarios, where traditional combat methods may not be effective.
