Colony of Aden
In 1962 the British Crown Colony of Aden became partially self-governing, before being incorporated into the Federation of South Arabia the following year. In addition to British units, Aden and the hinterland territories making up the Protectorate were garrisoned by a number of locally recruited units under British and Arab officers. On 1 June 1967 these were amalgamated to form the South Arabian Army (SAA). Since 1931 a gendarmerie style force called the Aden Armed Police had been responsible for maintaining order in Aden itself.
