Door-busting equipment is a term used to describe the tools used by law enforcement officers to gain entry into a building or vehicle. The most common tool used is a RAM, which stands for Rapid Access Mechanism. This device is a hydraulic RAM that is used to break down doors and other barriers. It is usually mounted on a vehicle and operated by a trained operator. Other door-busting equipment includes battering rams, sledgehammers, and crowbars. All of these tools are used to gain access to a building or vehicle in order to apprehend suspects or search for evidence.
