The main insignia which separates MSC from regular officers is the "SC & Crown" which is worn at the top of the epaulette by MSC officers of all ranks. Special Constables wear their
"Borough Code", usually a two-letter code, which signifies which BCU or specialist unit they are attached to. Below this, at the bottom of their epaulette, is their
Collar number, a four digit number beginning with a 5 or 8 if attached to
Roads and Transport Policing Command or 9 if attached to Organised Crime. A Special Sergeant's insignia is similar to a Special Constable's except they have a 4-digit shoulder number beginning with 50 (or 80 for RTPC, 90 for Organised Crime). Officers ranked above sergeant do not wear borough codes or shoulder numbers. Unlike epaulette insignia, the Metropolitan Special Constabulary have the same
Uniform Insignia as the Metropolitan Police where the Special ranks have equivalent designs as well as the Assistant Chief Officer wears equivalent uniform to a Commander/Assistant Chief Constable and the Chief Officer wears equivalent uniform to the Commissioner/Chief Constable. ==See also==
