Military - note

the UK is a member of NATO and was one of the original 12 countries to sign the North Atlantic Treaty (also known as the Washington Treaty) in 1949; the UK is also a member of the Five Powers Defense Arrangements (FPDA), a series of mutual assistance agreements reached in 1971 embracing Australia, Malaysia, New Zealand, Singapore, and the UK; the FPDA commits the members to consult with one another in the event or threat of an armed attack on any of the members and to mutually decide what measures should be taken, jointly or separately; there is no specific obligation to intervene militarily

in 2010, France and the UK signed a declaration on defense and security cooperation that included greater military interoperability and a Combined Joint Expeditionary Force (CJEF), a deployable, combined Anglo-French military force for use in a wide range of crisis scenarios, up to and including high intensity combat operations; the CJEF has no standing forces but would be available at short notice for UK-French bilateral, NATO, EU, UN, or other operations; combined training exercises began in 2011; as of 2020, the CJEF was assessed as having full operating capacity with the ability to rapidly deploy over 10,000 personnel capable of high intensity operations, peacekeeping, disaster relief, and humanitarian assistance

in 2014, the UK led the formation of the Joint Expeditionary Force (JEF), a pool of high-readiness military forces from Baltic and Scandinavian countries able to respond to a wide range of contingencies both in peacetime and in times of crisis or conflict; its principal geographic area of interest is the High North, North Atlantic, and Baltic Sea regions, where the JEF can complement national capabilities or NATO’s deterrence posture, although it is designed to be flexible and prepared to respond to humanitarian crises further afield; the JEF consists of 10 countries (Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, the Netherlands, Norway, Sweden, and the UK) and was declared operational in 2018; most of the forces in the pool are British, and the UK provides the most rapidly deployable units as well as the command and control elements

the British Armed Forces were formed in 1707 as the armed forces of the Kingdom of Great Britain when England and Scotland merged under the terms of the Treaty of Union; while the origins of the armed forces of England and Scotland stretch back to the Middle Ages, the first standing armies for England and Scotland were organized in the 1600s while the navies were formed in the 1500s; the Royal Marines were established in 1755; the Royal Air Force was created in April 1918 by the merger of the British Army's Royal Flying Corps and the Admiralty's Royal Naval Air Service (2022)
