Rear Admiral (United Kingdom)
Rear admiral (RAdm) is a flag officer rank of the Royal Navy. It is immediately superior to commodore and is subordinate to vice admiral. It is a two-star rank and has a NATO ranking code of OF-7. The equivalent rank in the British Army and Royal Marines is major-general; and in the Royal Air Force it is air vice-marshal.

Imperial War Museum
The Imperial War Museum (IWM), currently branded "Imperial War Museums", is a British national museum. It is headquartered in London, with five branches in England. Founded as the Imperial War Museum in 1917, it was intended to record the civil and military war effort and sacrifice of the United Kingdom and its Empire during the First World War. The museum's remit has since expanded to include all conflicts in which British or Commonwealth forces have been involved since 1914. As of 2012, the museum aims "to provide for, and to encourage, the study and understanding of the history of modern war and 'wartime experience'."
