After the partitioning of India in 1947, the Pakistan Army was formed by Indian Muslim officers serving in the British Indian Army. The largest branch of the nation's military, it is a professional, volunteer fighting force, with about 550,000 active personnel and 500,000 reserves (though estimates vary widely). Although, the Constitution provides a basis for the service draft, conscription has never been imposed in Pakistan. A single command structure known as General Headquarters (GHQ) is based at Rawalpindi Cantt, adjacent to the Joint staff HQ. The army is commanded by the Chief of Army Staff (COAS), by statute a four-star army general, appointed by the president with the consultation and confirmation of the prime minister. General Qamar Javed Bajwa was the chief of army staff. Army General Zubair Mahmood Hayat is the current chairman Joint Chiefs of Staff Committee. The army has a wide range of corporate (e.g.: Fauji Foundation), commercial (e.g.: Askari Bank), and political interests, and on many occasions has seized control of the civilian government to restore order in the country.
