The Chief of Army Staff of Pakistan Army, shortly abbreviated as COAS, is the highest staff post in the Pakistan Army, held by the senior 4-star rank officer. It is the highest and most prestigious 4-star assignment, unless the 4-star officer is appointed as the Chairman of the Joint Chiefs of Staff Committee of the Pakistan Armed Forces. The current Chief of Army Staff is General Ashfaq Parvez Kayani. The COAS operates from Army Combatant General Headquarters (GHQ) in Rawalpindi, the twin city of the capital Islamabad. Under the Constitution of 1973 presently in vogue, the Chief of Army Staff is subordinate to the Prime Minister of Pakistan and the President of Pakistan, and reports directly to the civilian leadership.
