Police tactical unit

A police tactical unit (PTU) is a specialized police unit trained and equipped to handle situations that are beyond the capabilities of ordinary law enforcement units because of the level of violence (or risk of violence) involved. The tasks of a police tactical unit may include executing dangerous search warrants and arrest warrants for dangerous persons; arresting or neutralizing dangerous or mentally ill armed persons; and intervening in high-risk situations such as shootouts, standoffs, hostage-takings, and terrorist incidents.
