An equerry (; from French 'stable', and related to 'squire') is an officer of honour. Historically, it was a senior attendant with responsibilities for the horses of a person of rank. In contemporary use, it is a personal attendant, usually upon a sovereign, a member of a royal family, or a national representative. The role is equivalent to an aide-de-camp, but the term is now prevalent only in the Commonwealth of Nations. Australia Australian equerries are commissioned officers in the Australian Defence Force, appointed on an ad hoc basis to the King of Australia, Governor General, state governors or to visiting foreign heads of state. Canada Canadian equerries are drawn from the commissioned officers of the Canadian Armed Forces, and are most frequently appointed to serve visiting members of the Canadian Royal Family. The equerry appointed for the King of Canada is a senior officer, typically a major or a lieutenant-commander, while the equerry appointed for a child of the monarch is a junior officer, typically a captain or naval lieutenant. Canadian equerries are also sometimes appointed to serve national representatives of the country. Colonel the Hon Henry Jackman of The Governor General's Horse Guards, Canada's Household Cavalry regiment, is the equerry to Akaash Maharaj, in the latter's role as head of UNICEF Team Canada. New Zealand New Zealand equerries are appointed to serve the King of New Zealand only for the duration of a royal visit to the country, and are always drawn from the officers of the New Zealand Defence Force, typically captains, flight lieutenants, and navy lieutenants. Squadron Leader Leanne Woon of the Operational Support Squadron, part of the Royal New Zealand Air Force, was the equerry to the Queen of New Zealand during the most recent royal visit in 2002. She is the only woman to serve as an equerry to the monarch anywhere in the Commonwealth.
