as they have historically staffed the summer public duties detachment, before membership in the Ceremonial Guard was opened to the entire Canadian Armed Forces. The Ceremonial Guard are considered an ad hoc detachment, as its members are drawn from various units of the armed forces, and does not constitute a permanent unit in the Canadian Forces' order of battle. The Canadian Armed Forces also maintains a National Sentry Program, where its members perform sentry duties at the National War Memorial from early-April to 10 November, the day before Remembrance Day. The program formally falls under the command structure of the Ceremonial Guard, although its volunteers are permitted to wear the ceremonial dress uniforms of their respective units/service while performing public duties at the war memorial. Quebec City Public duties at the Citadelle of Quebec, a military installation in Quebec City, are carried out by the Royal 22nd Regiment. The regiment carries out public duties at the Citadelle of Quebec from late-June to Labour Day, which falls on the first Monday of September. The military installation serves as the home garrison for the regiment, as well as the secondary official residence for the Monarch, and Governor General of Canada. The regiment has carried out public duties at the Citadelle since 1928, excluding a brief hiatus from 1939 to 1945, due to the Second World War. Denmark There are two regiments in Denmark, who provide soldiers for public duties, the Royal Life Guard regiment and Guard Hussar Regiment. The Guard Hussar Regiment Mounted Squadron provide mounted escorts for the Royal family and foreign dignitaries, and carry ceremonial services for the Royal Danish Army. The Royal Life Guards provide a permanent guard at the Amalienborg Palace, Kastellet (part of the old fortification of Copenhagen), Rosenborg Castle/garrison of the Royal Life Guards in Copenhagen and the garrison of Høvelte. On occasions guard is kept at Fredensborg Palace, Marselisborg Palace, Gråsten Palace, Christiansborg Palace and other locations inside the Danish realm. Germany The Wachregiment Berlin was founded in early 1921. In addition to genuine security duties, the unit was used for ceremonial public duties in the capital. The regiment was disbanded in June 1921 and shortly after was revived as Kommando der Wachtruppe (lit. Headquarters Guard Troop). The Wachtruppe comprised seven companies, each drawn from one of the seven active army divisions. Each company served for three months before returning to its parent division. In
