The Headquarters Mobile Support Unit (HMSU) was a special unit established in 1978 (?) by the Royal Ulster Constabulary (RUC) and was intended to be the RUC equivalent of the Special Air Service (SAS). Members of the HMSU were drawn from RUC Special Branch and were trained by the SAS to on how to confront Irish Republican Army (IRA) members with 'firepower, speed and aggression'. The unit worked in collaboration with an RUC intelligence gathering unit called E4A. The HMSU was responsible for several 'shoot-to-kill' incidents in Northern Ireland during November and December 1982. Reading: Taylor, Peter. (2001) Brits: The War Against the IRA.
