Army & Navy Stores was a department store group in the United Kingdom, which originated as a co-operative society for military officers in the nineteenth century.
 The society became a limited company in the 1930s and purchased a number of independent stores during the 1950s and 1960s.
 In 1976 the Army and Navy Stores group was acquired by House of Fraser.
 From 2005 onwards the remaining Army & Navy stores (the flagship store located on Victoria Street in London and the three others in Maidstone, Camberley, and Chichester) were refurbished and re-branded as House of Fraser stores.
 House of Fraser itself was acquired by Icelandic investment company, Baugur Group, in late 2006.

 He commanded units of the Royal Flying Corps and Royal Air Force in the First World War, and served as Chief of the Air Staff during the first years of the Second World War.

 He was a pilot and squadron commander in the Royal Flying Corps in the First World War and he went on to serve as a senior officer in the Royal Air Force during the inter-war years when he served in Turkey, Great Britain and the Far East.
 During the Second World War, as Air Officer Commanding RAF Middle East Command, Tedder directed air operations in the Mediterranean and North Africa, including the evacuation of Crete and "Operation Crusader" in North Africa.
 His bombing tactics became known as the "Tedder Carpet".
 Later in the war Tedder took command of Mediterranean Air Command and in that role was closely involved in the planning of the Allied invasion of Sicily and then the Allied invasion of Italy.
 When Operation Overlord—the invasion of France—came to be planned, Tedder was appointed Deputy Supreme Commander at Supreme Headquarters Allied Expeditionary Force under General Eisenhower.
 After the war he served as Chief of the Air Staff, in which role he advocated increased recruiting in the face of many airmen leaving the service, doubled the size of RAF Fighter Command and implemented arrangements for the Berlin Airlift in 1948.

The following is a list of senior Royal Flying Corps generals.
 While officially general officers are not considered to belong to any regiment or corps (simply being "late" of their erstwhile regiment), in practice almost all the general officers to hold a Royal Flying Corps-related appointment gained their promotion to the general officer ranks in that appointment and remained in such appointments until the creation of the Royal Air Force on 1 April 1918.
 Royal Flying Corps generals then became Royal Air Force generals.
Air Chief Marshal Sir James Milne Robb, {'1': ", '2': ", '3': ", '4': "} (26 January 1895 – 18 December 1968) was a senior Royal Air Force commander.

 In 1939, Robb travelled to Canada to help establish the Empire Air Training Scheme, a massive training program that provided the Royal Air Force with trained aircrew from Canada, Australia, New Zealand and Southern Rhodesia.
 He commanded No. 2 Group RAF of RAF Bomber Command and No. 15 Group RAF of RAF Coastal Command.
