Barney, SB means Special Branch , the much feared special secret investigation and interrogation unit of the police department. Any visit by the SB truly sparks fear to the average person and political and social dissidents are known to be the whipping boys and lab rats of this unit. SB can be loosely compared to MI6 or FBI. The UTK stands for Unit Tindakan Khas, literally the Special Action Unit akin to the special forces or SWAT teams. They are usually deployed in hostage taking situations, hijackings or even extreme riot control in conjunction with the Police Field Force.
