British Military Hospitals were established and operated by the British Army, both at home and overseas during the 19th and 20th centuries, to treat service personnel (and others in certain circumstances). They varied in size, purpose and permanence.
Until the latter part of the 20th century the term 'Military Hospital' in British usage always signified a hospital run by the Army, whereas those run by the Navy were designated Royal Naval Hospitals and those run by the Royal Air Force RAF Hospitals. In the UK the last of these Military Hospitals were closed in the 1990s, replaced by a single tri-service hospital (which was itself closed in 2007); since then, service personnel (except when deployed on active service) have usually been treated in civilian (NHS) hospitals (some of which have had integrated Ministry of Defence Hospital Units provided as part of their establishment).
