conscription does not exist
Conscription has never existed in Pakistan.
The 1952 Pakistan Army Act does provide for the possible introduction of compulsory military service in times of emergency, but this has never been contemplated by the authorities. Voluntary applications to join the armed forces are usually sufficient to achieve the requisite number of recruits. 
Most recruits come from northern Punjab and the North-West Frontiers province. This was already the case when Pakistan was still part of the British Empire. 
Legal enlistment age is between the ages of 17 and 22 for officers, and between 16 and 25 for soldiers.
