Lieutenant general (United Kingdom)

Lieutenant general (Lt Gen), formerly more commonly lieutenant-general, is a senior rank in the British Army and the Royal Marines. It is the equivalent of a multinational three-star rank; some British lieutenant generals sometimes wear three-star insignia, in addition to their standard insignia, when on multinational operations.

Lieutenant general is a superior rank to major general, but subordinate to a (full) general. The rank has a NATO rank code of OF-8, equivalent to a vice-admiral in the Royal Navy and an air marshal in the Royal Air Force (RAF) and the air forces of many Commonwealth countries.

The rank insignia for both the Army and the Royal Marines is a crown over a crossed sabre and baton. Since the coronation of Queen Elizabeth II, the St Edward's Crown, commonly known as the Queen's Crown, has been depicted. Prior to 1953, the Tudor Crown, commonly known as the King's Crown was used.

Ordinarily, lieutenant general is the rank held by the officer in command of an entire battlefield corps. The General Officer Commanding NATO's Allied Rapid Reaction Corps is a British lieutenant general. Historically, I Corps and II Corps were commanded by British lieutenant generals. Additionally, three lieutenant general appointments also exist within the extant British Army's Headquarters. They are the Commander Field Army, the Commander Home Command and the Chief of Materiel (Land) in Defence Equipment and Support (double-hatted as the Quartermaster-General to the Forces).
