The Headquarters Mobile Support Unit (HMSU) was a special unit of the Royal Ulster Constabulary.

Background[edit]

The Headquarters Mobile Support Unit (HMSU) was a uniformed elite unit established by the Royal Ulster Constabulary (RUC), intended to be the RUC equivalent of the Special Air Service (SAS). Members of the HMSU were enrolled into RUC Special Branch and were trained by the SAS to on how to confront Irish Republican Army (IRA) members and other opponents with "firepower, speed and aggression".[1]

The unit had its prototype in the Bessbrook Support Unit (BSU) set up in 1977 as part of the scaling-up of the RUC's numbers and capabilities under Chief Constable Kenneth Newman to "Ulsterise" as far as possible the maintenance of security. The intensively trained and highly armed BSU were intended to take over from the SAS the role of deployment along the South Armagh border to intercept IRA active service units. The BSU were in 1979 replaced with a Special Patrol Group (SPG), which was in turn replaced in 1981 by the Special Support Unit (SSU).[2] The SSU was subsequently renamed the Headquarters Mobile Support Unit (HMSU) as the initials SSU were considered too similar to SAS, suggesting a military-style unit.[3]

"Shoot to kill"[edit]

The SSU were infamously involved in the alleged "shoot-to-kill" incidents of November and December 1982, when six republican paramilitaries were shot dead in three separate incidents, all of whom turned out to be unarmed. These incidents, and evidence which came out in court of organised falsification of the details of the encounters, led to the setting up of the 1984–86 Stalker Inquiry.

In this period, according to evidence given in court at the time by RUC deputy chief constable Michael McAtamney, officers selected for the unit underwent an immensely tough two-week assessment of fitness, mental ability and endurance under pressure, followed by a four-week course including seven days devoted exclusively to weapons training; with the focus being to "eliminate the threat" posed to officers.[3]

In addition to standard RUC weaponry, the unit additionally used Uzi sub-machine guns; Remington pump-action shotguns and Browning semi-automatic shotguns; the Ruger mini-light automatic rifle; and 14-shot, 54 Smith and Wesson magnums, carried as personal sidearms.[3] According to one subsequent report, at the time of the 1982 shootings, the HMSU that had been active in the RUC southern region comprised two dozen men, working in field teams of six, travelling in pairs of specially armoured unmarked Ford Cortinas, the front passenger with a Sterling submachine gun, the rear passenger a Ruger rifle, and all three including the driver were armed with pistols.[4]

The unit was based at RUC Lisnasharrah, East Belfast, and worked closely with the RUC plain-clothes intelligence gathering unit E4A. Many were English and/or ex-soldiers. According to reports, as uncovered by the Stalker Inquiry, the units operated almost as a law unto themselves, taking orders only from a small group at Gough Barracks in Armagh that was in charge of tasking and co-ordination, who in turn answered only to Special Branch at RUC headquarters at Knock. Members generally refused to recognise the authority of senior officers not in the unit, a constable on one occasion telling a CID detective to leave the site and come back after he had had a meal.[3][4]

According to American writer J. Bowyer Bell there were two such units in all at the time, of 24 members each;[5] although a 1985 newspaper article claimed at least 12 such squads were active.[6] The same article explained their rationale: "The circumstances of the shootings have to be put into the context of Northern Ireland. In the same period two RUC officers who approached a car parked outside a County Down post office were shot dead by IRA men about to stage a robbery. Unionists were not slow to claim that if anyone was shooting to kill, it was the Republican paramilitaries."[6]

Post 1982[edit]

Following the 1982 shootings, the role of the HMSU was reined back. Subsequently the RUC would play a supporting role in such operations, but the active role in intelligence-led covert ambushes was returned to the British Army, in particular the SAS and similarly-trained army units, though under ultimate police operational control.[7]

Tasking of counter-terrorist operations was put into the hands of a joint committee that included army intelligence, MI5 and MI6 as well as senior police officers, rather than the original exclusive tight control by a close-knit small group of RUC officers reporting to HQ-level Special Branch. Some measures were also taken to make the Special Branch less of a force within a force, with regional RUC assistant chief constable having to be informed of Special Branch operations in their areas, and a single senior assistant chief constable position created, with oversight responsibility for both CID and Special Branch.[8] The HMSU continued to take part in "rapid reaction" duties, including raids on suspected terrorist properties, and spearheading riot control.

The HMSU continued in being throughout the 1980s and 1990s as an operational sub-department of Special Branch department E4.[9] In this time the unit traced and arrested several IRA members in Northern Ireland.[citation needed]

Now with the level of threat posed by terrorism in Northern Ireland is not as high as in previous years the unit currently responsd to high risk police duties such as drug raids, armed response, etc. whilst monitoring the Real IRA and other dissident groups, ready to respond to any terrorist activity in Northern Ireland. HMSU is now located within the PSNI's C4 Special Operations Branch.[10] They work and train closely with the Republic of Ireland's Garda Emergency Response Unit (ERU).[11]

Divisional Mobile Support Units (DMSUs), attached to each police division, have also existed. The DMSUs have now been renamed Tactical Support Groups (TSGs).[citation needed]
