  Overseas military installations of the United Kingdom, and locally raised units of British Overseas Territories.

The British Armed Forces maintain a number of overseas garrisons and military facilities which enable the country to conduct operations worldwide. The majority of Britain's permanent military installations are located on British Overseas Territories (BOTs) or former colonies which retain close diplomatic ties with the United Kingdom, and located in areas of strategic importance.^[14] The most significant of these are the "Permanent Joint Operating Bases" (PJOBs), located on the four overseas territories of Cyprus (British Forces Cyprus), Gibraltar (British Forces Gibraltar), the Falkland Islands (British Forces South Atlantic Islands) and Diego Garcia (British Forces British Indian Ocean Territories).^[88] While not a PJOB, Ascension Island (another BOT) is home to the airbase RAF Ascension Island, notable for use as a staging post during the 1982 Falklands War, the territory is also the site of a joint UK-US signals intelligence facility.^[14]
Qatar is home to RAF Al Udeid, a Royal Air Force outpost at Al Udeid Air Base which serves as the operational headquarters for No. 83 Expeditionary Air Group and its operations across the Middle East.^[89] A large Royal Navy Naval Support Facility (NSF) is located in Bahrain, established in 2016 it marks the British return East of Suez.^[90] In support of the Five Power Defence Arrangements (FPDA), the United Kingdom retains a naval repair and logistics support facility at Sembawang wharf, Singapore.^[14][91] Other overseas military installations include; British Forces Brunei,^[92] British Forces Germany,^[93] the British Army Training Unit Kenya,^[94] British Army Training Unit Suffield in Canada,^[95] British Army Training and Support Unit Belize, and British Gurkhas Nepal.^[96]
Some British Overseas Territories also maintain locally raised units and regiments; The Royal Bermuda Regiment, the Falkland Islands Defence Force, the Royal Gibraltar Regiment, the Royal Montserrat Defence Force, the Cayman Islands Regiment, and the Turks and Caicos Regiment. Though their primary mission is "home defence", individuals have volunteered for operational duties. The Royal Gibraltar Regiment mobilised section-sized units for attachment to British regiments deployed during the Iraq War.^[97][98] The Isle of Man, a Crown dependency hosts a multi-capability recruiting and training unit of the British Army Reserve.^[99]
Since 1969 Britain has had a military satellite communications system, Skynet, initially in large part to support East of Suez bases and deployments. Since 2015 Skynet has offered near global coverage.^[100]
