The Special Coruscant Protection Divisions, or SPCD, was a group of highly trained elite soldiers dedicated to protecting Coruscant from crime and villainy. Each Division, of which there were four, consisted of six Officers and one Captain.
The SPCD was created around 652 BBY, for the purpose of taking down criminals to large for common police and too small for Jedi.
Technically, the SPCD would be considered illegal, as the entire Senate never approved of the idea, mainly because the Chancellor and a handful of important Senators thought it would be best if as few people knew about the operation as possible.
