The Special Deployment Unit (S.D.U.) has 25 members consisting of deputies from detentions, patrol, and court services. S.D.U. also has civilian specialists who assist with filming at events. The filming assists the unit in the event of any civil or criminal complaints. The S.D.U. has many functions and tasks it can perform including, warrant roundups, mass evacuations, assist with scene security during man made or natural disasters, dignitary protection, riot control, and any other task assigned by the Sheriff.
During any given assignment, the deputies can change from low profile uniforms to what is commonly called the “turtle suit.” The turtle suit consists of a ballistic helmet, gas mask, chest and arm protectors, and knee and shim protection. Turtle Suits are mainly used during riot and crowd control situations. The team also has a trailer with specialized equipment for deploying gas and less lethal munitions, and cutting and dismantling obstructions demonstrators might erect to block access to buildings or roadways.
The Special Deployment Unit has participated in several community related projects such as National Night Out, Bring Your Child to Work Day, Castle Rock Street Fair, and the Highlands Ranch Farmers Market. The Special Deployment Unit has trained with the Douglas County K-9, Mounted Patrol, SWAT, and SORT teams, El Paso, Arapahoe, and Jefferson counties, and several area police and fire agencies. S.D.U. has also worked with the Air Force Academy.
