In Aden in 1966 a unit of the pioneers carried out a speed demonstration in which they erected a Twynham hut in four minutes. The huts could be readily dismantled and reused elsewhere as was done later in 1966 and 1967 when the British withdrew from the country. Lieutenant-colonel Gus Sinclair recovered 85 Twynham huts from an abandoned British base in the aftermath of the September 1969 Libyan coup d'état. The Twynham huts were still in use in 1982 when they formed part of the aircrew accommodation at Wideawake airfield on Ascension Island during the Falklands War.
