Specialist Operations

Specialist Operations is a directorate of the Metropolitan Police. At its peak, SO was a group of twenty specialist units, which were formed to give the Metropolitan Police a specialist policing capability. The SO designation was implemented in 1986 as part of Sir Kenneth Newman's restructuring of the Metropolitan Police Service. Most of the units designated SO units were already in existence, many of them as departments of C Division and its branches, and all were presided over by an Assistant Commissioner of Special Operations (ACSO).
