The Pakistan Army (Urdu: پاکستان فوج) is the principal land warfare branch of the Pakistan Armed Forces. The roots of its modern existence trace back to the British Indian Army that ceased to exist following the partition of British India, resulting in the parliamentary act that established the independence of Pakistan from the United Kingdom on 14 August 1947.[5]:1–2 According to the estimation provided by the International Institute for Strategic Studies (IISS) in 2017, the Pakistan Army had approximately 650,000 active-duty personnel, supported by the Army Reserve and National Guard[6][7]—effectively making it the 6th largest army in the world in terms of manpower.[8][9] Citizens can enlist for voluntary military service upon reaching 16 years of age and cannot be deployed for combat until age 18 in accordance with the Constitution of Pakistan.[10]
