The Sheriff’s Office supports a specialized tactical unit known as the Special Operations Unit (SOU). It was formed in 1990 and is a multi-agency team that conducts training exercises on a regular basis. The unit is supported by a tactical medical unit and stands ready to deploy 24 hours a day, 7 days a week. The SOU is able to respond to incidents that go beyond the scope of normal patrol capabilities such as barricaded suspects, armed suspects, suicidal persons, hostage rescue, dignitary protection and crowd control. The team has trained with the Federal Bureau of Investigation (FBI), Colorado National Guard High-Altitude Army Aviation Training Site (HAATS), military resources and other specialized law enforcement agencies.
