synonyms: Headquarters Mobile Support Units (HMSU) Also known as Headquarters Mobile Support Units (HMSU) these were special units formed within the Royal Ulster Constabulary (RUC) to handle incidents such as widespread public disorder and to act on information relating to suspected paramilitary activity. This latter activity gave rise to allegations from republicans that in certain incidents, instead of attempting to arrest and bring before the courts those apprehended, members of the MSU resorted to 'shoot to kill' tactics.
