Royal Canadian Mounted Police
The Royal Canadian Mounted Police (RCMP) was formed in 1920 by the merger of the Royal Northwest Mounted Police (RNWMP), founded in 1873, with the Dominion Police founded in 1868. The former was originally named the North West Mounted Police (NWMP), and was given the "Royal" prefix by King Edward VII in 1904. Much of the present-day organization's symbolism has been inherited from its days as the NWMP and RNWMP, including the distinctive Red Serge uniform, paramilitary heritage, and mythos as a frontier force. The RCMP-GRC wording is protected under the Trade-marks Act.
Despite its name, the RCMP is no longer an actual mounted police force, with horses only being used at ceremonial events. The predecessor NWMP and RNWMP had relied on horses for transport for most of their history, though the RNWMP was switching to automobiles at the time of the merger.
Rocky Mountain Rangers (1885)
The Rocky Mountain Rangers were one of the volunteer militia units raised in Canada's North West in response to the 1885 North-West Rebellion. It was a body of mounted irregulars, mostly cowboys and ranchers from the area around Fort Macleod (District of Alberta), the headquarters of the North-West Mounted Police (NWMP) located at the base of the foothills of the Rocky Mountains, about west of Medicine Hat (in what was then the District of Assiniboia). This unit is not to be confused with the present-day Canadian Army Reserve unit The Rocky Mountain Rangers of Kamloops, British Columbia. Rather, it is the ultimate ancestor of the South Alberta Light Horse.
