Commander-in-Chief of the Pakistan Army
The Commander-in-Chief of the Pakistan Army was the professional head of the Pakistan Army from 1947 to 1972. As an administrative position, the appointment holder had main operational command authority over the army.
Direct appointments to the command of the Pakistan Army came from the British Army Council until 1951, when the first native Pakistani commander-in-chief was nominated and appointed by the Government of Pakistan.
The C-in-C designation was changed to 'Chief of Army Staff' in 1972; General Tikka Khan was the first person to hold the new title. Six generals have served as C-in-C, the first two of them were native British and the post's name was derived from the post of Commander-in-Chief of the British Indian Army.
