The Military Museums is a reorganization of the former Museum of the Regiments in Calgary, Alberta, announced by Sophie, Countess of Wessex, on June 3, 2006. The new museum comprises the former Museum of the Regiments as well as the relocated Naval Museum of Alberta and an Air Force Wing consisting of artifacts being acquired. History The Museum of the Regiments was formally opened by Queen Elizabeth II on 30 June 1990, on what was then CFB Calgary. The museum, partnered with the Calgary Military Museums Society (CMMS), was a joint venture of the four military regiments in Calgary at that time, each with its own gallery. The Military Museums preserves and documents the history of all three environmental commands of the Canadian Forces, the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force, with a focus on Alberta history, through an extensive public gallery and archival holding. The museum collects, preserves, arranges, catalogues, interprets and exhibits to the public and members of CFB Calgary, the history of the base (which closed in 1998) and its garrison units. The goal is to stimulate the interest in the history of the base to all personnel of the base, and the general public to cooperate with other organizations having similar objectives. Memorials On 11 August 1989, Patricia Knatchbull, 2nd Countess Mountbatten of Burma, the colonel-in-chief of Princess Patricia's Canadian Light Infantry, dedicated a memorial consisting of a granite base, metal bowl and two metal plaques to the memory of the war dead of the founding regiments of the museum: Lord Strathcona's Horse (Royal Canadians); King's Own Calgary Regiment; Princess Patricia's Canadian Light Infantry and The Calgary Highlanders. A brass plaque memorial, erected by the Manitoba Association of Lord Strathcona's Horse (Royal Canadians), is dedicated to the members of the regiment killed since 1900. A certificate lists the officers killed during the Second World War while serving with Lord Strathcona's Horse (Royal Canadians). A brass plaque, erected by local Jewish servicemen, is dedicated to the memory of local Jewish war dead of the First and Second World Wars. The Canadian Peacekeepers Roll of Honour at the museum's Southern Alberta Gallery lists the names of Canadians killed on peacekeeping duty from 1939 to 1993 The Naval Museum of Alberta Society and the Calgary naval community erected a memorial dedicated to all Royal Canadian Navy sailors who served, and particularly to those who died,
