The insignia of rank is a crown above a Bath Star, known as "pips", above crossed tipstaves within a wreath, very similar to the insignia worn by a full general in the British Army. This badge is all but unique within the British police, shared only with the Commissioner of the City of London Police, the smallest territorial police force, and HM Chief Inspector of Constabulary. Like all chief officer ranks in the British police, commissioners wear gorget patches on the collars of their tunics. The gorget patches are similar to those worn by generals, aside from being of silver-on-black instead of the Army's gold-on-red.
