In May 1947, the School was re-designated the School of Land/Air Warfare, training Air Force, Army and Navy officers from both the UK and other NATO countries. On 26 June 1956, in recognition of its importance and longevity, RAF Old Sarum was honoured by being given the Freedom of the City of Salisbury. At about the same time, the station also became the home of the Army Air Training and Development Centre which, although 'officed' by the Parachute Regiment, mainly consisted of other corps. REME developed parachute drops of light vehicles and artillery whilst RE undertook the training.
