The Hampstead Heath Constabulary consists of 13 constables. In 1879 a 1,200-member armed paramilitary Hausa Constabulary was formed. The Kiaps were commissioned as officers of the Royal Papua New Guinea Constabulary and Magistrates. French military observers similarly reported on the "Royal Irish Constabulary (the Irish gendarmerie)". Glossop Police remained independent until 1947 when they amalgamated with the Derbyshire Constabulary. Later on, contingents of Canadians served with the paramilitary South Africa Constabulary. Bruce Robertson is a detective sergeant serving in Edinburgh's "Lothian Constabulary". The authorities there raised their own reserve force, the Ulster Special Constabulary. The UPPAC is headed by the Director General Provincial Armed Constabulary. The occupying force soon established a Dominican army constabulary to impose order. Its members transferred to the Armed Constabulary. In country areas, sergeants are often in charge of an entire station and its constabulary. The 7th was formed from the Zanzibar Armed Constabulary and the Mafia Constabulary. These ultimately led to the disbanding of the Ulster Special Constabulary. This was a large, three-day riot between Irish nationalists and the Royal Ulster Constabulary (RUC).
