Members of the Royal Family, including the sovereign, take on honorary appointments—known as "royal appointments"—related to army regiments or air force or navy units; a practice that is thought to have originated with the appointment of Princess Louise, Duchess of Connaught, as Colonel-in-Chief of the 199th Battalion in 1917. The appointment, intended as an honour for regiments and units and to reinforce loyalty to the Crown, is made by the Crown-in-Council (the monarch or the governor general acting on the advice of Cabinet) and the appointee—known as an "honorary"—acts akin to a patron and holds the role either for life or until voluntarily stepping down or the unit or regiment is disbanded. Positions include colonel-in-chief, captain general, commodore-in-chief, admiral, and others. Requests for a royal honorary are made by the regiment or unit through the chain of command and a holder is indended to be a "guardian of Regimental traditions and history, promotthe regiment's identity and ethos and [be an advisor to the Commanding Officer on virtually all issues excluding operations." They will carry out a number of associated duties, such as attending regimental dinners, presenting new colours, trooping the colour, and viewing field training exercises. Attendance and participation in these events may be at the direction of the ministers of the Crown or the regiment itself. As members of the Canadian Forces, royal honoraries may wear forces' uniforms, both dress and operational.
