The Royal Gibraltar Regiment is part of British Forces Gibraltar for the British overseas territory of Gibraltar, which historically, along with Bermuda, Halifax, Nova Scotia, and Malta, had been designated an Imperial fortress rather than a colony. It was formed in 1958 from the Gibraltar Defence Force as an infantry unit, with an integrated artillery troop. The regiment is included in the British Army as a defence engagement force.

British Forces Gibraltar is the British Armed Forces stationed in the British overseas territory of Gibraltar. Gibraltar is used primarily as a training area, thanks to its good climate and rocky terrain, and as a stopover for aircraft and ships en route to and from deployments East of Suez or in Africa.
