Admiralty
It evolved from *Admiralty Navy War Council, (1909–1912) which in turn became the Admiralty War Staff, (1912–1917) before finally becoming the Admiralty Naval Staff in 1917. It was the former senior command, operational planning, policy and strategy department within the British Admiralty. It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished, and the staff departments function continued within the Navy Department of the Ministry of Defence until 1971 when its functions became part of the new Naval Staff, Navy Department of the Ministry of Defence.
History of the Royal Marines
The Royal Marine Artillery (RMA) was formed as an establishment within the British Royal Marines in 1804 to man the artillery in bomb vessels. This had been done by the Royal Regiment of Artillery, but a lawsuit by a Royal Artillery officer resulted in a court decision that army officers were not subject to naval orders. As their coats were the blue of the Royal Regiment of Artillery, this group was nicknamed the "Blue Marines" and the infantry element, who wore the scarlet coats of the British infantry, became known as the "Red Marines", often given the derogatory nickname "Lobsters" by sailors.
