The Chief of Army Staff (reporting name: COAS), is the four-star rank appointment in the Pakistan Army, held by the senior four-star ranking officer appointed and confirmed by the President of Pakistan, on a nomination approval summary sent by the Prime Minister of Pakistan. The Chief of Army Staff post has historically been vested with proportionately more powers because of the recurrent enforced military laws in the country. It is the highest and most prestigious four-star assignment, unless the four-star officer is appointed as the Chairman of the Joint Chiefs of Staff Committee of the Pakistan Armed Forces– the highest ranking officer who is senior to the Chiefs of Staff of Army, Air Force, Navy and respected chiefs of other military services.
