Pretty Simple Mike, Deployment sit in Dark Cars in High Crime area's of North, Northeast and Northwest parts of the city and Scan DPD patrol channels for crimes. When a crime is comitted in their area, they respond quietly and sit in the middle of the mix looking for the bad guys, if and when they find him, they set up a Very Complex surveillance operation and run video documenting the criminal act(s). In some cases they will bring in Narcotics, Vice, FBI, ATF or Rangers and issue a takedown to be prosecuted with "Organized" or "Rico" consequenses.
Origionally, Deployment was set up as an Auto-Theft Task force. But because they are so successful in Stealth, they eventually were assigned to High Crime areas to Investigate all crimes. If a Shooting comes out in NE (Ch-2) Deployment will "Flood" the area in un-marked to very non-recognizable police cars (Siezed, Borrowed from the Fed's, Leased, in some cases still stolen) and watch everything. With this approach, they can let DPD marked elements operate then Move on, the neighborhood calms down and returns to its own Crime State and Deployment are nesstled in with Video and Stealth surveillance rolling and eventually capture the culprits.
Deployment were used as the Intellegence edge for Operation Kitchen Sink and Disruption. Most are armed with AR's and operate on the TRS and have immediate NEXTEL access to High Command, Tactical, FBI and outside Police Agencies.
Deployment were trained by the FBI under Rathburn when Specialized DPD sharred offices with the FBI in the 80's and 90's. Also under Ben Clicks Term, then that African American Chief and Laura Miller broke that up and put them on the streets.
Deployment can operate 5 to 10 field units with a Un-Marked Crown Vic Sergeant with Computer sitting in the Distance running plates and acting as support. The Sergeant will also have realtime communications and updates citywide of crimes in progress and Investigative activities. Deployment will assist in US Marshall Warrant executions, SWAT Surveillance, Cold Tailing Chases, ect.
You can have Deployment sitting beside you at a red light and curse under your breath because they look just like the scumbags who makes Dallas Streets unsafe. Each Patrol Division have a Deployment detail and they work all shifts, they have their own Secretary at the Sub-Stations and seldome use Dispatched Channels to Go in and out of Service. Most of the time they are on Nextel with the Channel Dispatcher alike Patrol is on the UHF Radio. Deployment have their own Patrol beats also, Generally one Deployment beet is equivallient to three Patrol Beets. so Deployment beet 254, encompasses Patrol beet, 254, 255 and 253. Also, Deployment can go where ever they need to, they are not bound to their area or to the city. If the crime in progress takes them to other cities and counties, so beit.
If you are a Drug dealer, Crackhead, Hooker, Car thief or Burgular in Dallas, you Best Fear the Deployment/Covert unit, cuz there out there watching for you.
