Close Quarters Combat or Close Quarters Battle training involves the preparation of tactical teams for situations where a physical fight with firearms between multiple individuals at a particularly short range may occur. Shoot houses help enhance both the performance of tactical teams and the efficiency of their missions as they are configured to resemble residential, industrial, and commercial areas. Throughout training, ballistic shields can be implemented for various scenarios. Raids, high-risk search warrants, and active shooter situations can be practiced with ballistic shields using both offensive and defensive tactics. There are fundamental CQB principles alongside room clearing and target engagement that are among the most common practices for tactical teams when implementing a ballistic shield in a shoot house.
