# Chief of the Defence Staff (Sri Lanka)

The Chief of the Defence Staff (CDS) was the most senior appointment in the Sri Lankan Armed Forces, and the highest-ranking military officer in service, outranking the heads of each service branch. The CDS had not operational command authority over service branches, but rather oversaw inter-service co-operation and developed and implemented the joint operations doctrine of the Sri Lankan armed forces. Coordination of inter-service joint operations were handled by the Office of the Chief of the Defence Staff, formally known as the Joint Operations Headquarters.
The CDS was the Chairman of a Committee made up of service commanders and is a member of the National Security Council.
Its subordinate command was known as the Overall Operational Command.

## History

The post could be traced back to post of general officer commanding (GOC) of the Joint Operations Command when General T. I. Weerathunga was first appointed to it on November 2, 1985. The Joint Operations Command was created in 1985 due to a need to co-ordinate of joint operations among the tri-services and the police with the escalation of the Sri Lankan Civil War. The post itself was created in 1999 replacing the civilian post of chief of the Joint Operations Bureau which had existed briefly in 1999. Its powers expanded under the Chief of Defence Staff Act No. 35 of 2009.
The Chief of the Defence Staff was appointed to the highest rank in the branch of the Sri Lankan armed forces to which he belonged (equivalent to a British "four-star" rank) being a General, an Admiral or an Air Chief Marshal. According to the new Bill, the president of Sri Lanka appointed to the post of Chief of Defence Staff any person serving as Commander of the Army, Navy or the Air Force, to function under the direction, supervision and control of the permanent secretary to the Ministry of Defence.
