In the inter-war years one major role for the Royal Air Force was imperial defence. The Air Staff further argued that air power, used in substitution for the Army, would provide a more economical and effective means of policing and subjugating unrest in the remoter and more inaccessible areas of the colonial empire in Asia and Africa. The first successful major operation by the R.A.F. in Somaliland in 1920 encouraged the extension of air policing to the troublesome Middle East. The R.A.F. saw the Sudan as an integral part of its Middle East operations and throughout the late 1920s and 1930s military aircraft stationed in Khartoum were used to deal with revolt in the Southern Sudan. Continued Army opposition to substitution led the R.A.F. to seek a role in the sub-Saharan colonies. The need for defence economies as a result of the Depression, the Italian invasion of Ethiopia, and unrest on the Copperbelt persuaded the authorities in both London and the colonies of the need for an Air Force presence in East and Central Africa.
