The Office of Chief of Staff of the Sultan’s Armed Forces is the authority responsible for the coordination of multiple aspects related to operations, training, qualifications, services, media and the dissemination of military culture throughout the Sultan's Armed Forces in Oman. A number of the joint military institutions in the Sultan’s Armed Forces fall within its purview.
In 1955, the first central administrative command was formed of what was then known as the Muscat Armed Forces. The Muscat Infantry Commander was appointed as the Administrative Commander of all of the armed forces at the time. This was followed on 23 April 1958 by the appointment of a commander of the Sultan's Armed Forces. December 11, 1975 marked the occasion of the formal end of military operations after the Sultan’s Armed Forces successfully achieved lasting peace, security and stability in the Governorate of Dhofar. Shortly afterwards, planning was initiated to restructure the Defence Forces.
In 1976, the Sultan’s Armed Forces was reorganized into separate land, air and sea forces, with respective commanders for each service. The position of Commander of the Sultan’s Armed Forces was henceforth abolished which represented a major reappraisal of how the Defence Forces would be organized going forward. Subsequently, in 1979, the position of Chief of Defence Staff was created, although the first incumbent of this post, General Sir Timothy May Creasey, was not appointed until 5 August 1981. In 1987, the Ministry of Defence underwent further restructuring, resulting in the post of Chief of Defence Staff being replaced by Chief of Staff of the Sultan's Armed Forces.[1]
