"The Emergency Service Unit (ESU) is a police tactical unit which provides specialized equipment, expertise and support to the various units within the police departments. These police forces do not have a traditional S.W.A.T. unit. The Emergency Service Unit qualifies in the role of a S.W.A.T. unit and much more. From auto accidents to building collapses to hostage situations, \"ESU\" officers are called on when the situation requires advanced equipment and expertise. The Canine Unit provides assistance during searches for missing persons, perpetrators and evidence such as drugs and contraband."@en . . . . . . .
