  skos:definition "An Emergency Services Unit (ESU) is generally described as a unit within a police agency designated for meeting the specialized needs of the agency in terms of providing the ability for special enforcement or investigations, or a specialized or unique response on behalf of the agency most commonly regarding tactical operations, rescues, riots, hostage and rescue operations, and a variety of other high-risk emergency operations requiring a specialized tactical response, specialized training, and specialized equipment. In defining an ESU within a police department, a foundation must be created in order to place such a definition in its proper context.
