Door breaching

Door breaching is a process used by military, police, or emergency services to force open closed or locked doors. A wide range of methods are available depending on the door's opening direction (inward or outward), construction materials, etc., and one or more of these methods may be used in any given situation. In the United States, residential doors typically open inward while commercial building doors usually open outward. Some breaching methods require specialized equipment and can be categorized as one of the following: mechanical breaching, ballistic breaching, hydraulic breaching, explosive breaching, or thermal breaching.
