From 1947–71, the Pakistan's
Army GHQ had been a central and focal strategic planning center for military operations with most taken on army's point of view. The Pakistani troops and sailors deployed in the
Eastern Command and the Western formations had fought
Indian Armed Forces without the mission clarity and without the ground, air, and sea line of strategic communication. In 1976, the bureaucratic structure was modeled and build in an accelerated schedule by establishing the JS HQ, which was set up to improve coordination, command, and communication between the branches of the
Pakistan Armed Forces. In 1977, the JS HQ began to issue directives on mission parameters and requirements for development of nuclear weapon design to the nation's weapons laboratories. In 1984—86, many of the Army GHQ's directorates, mainly the weapon system procurement, deployments, weapon selections, and overall mission preparedness and execution of the military operations, were transferred to the JS HQ in light of recommendations provided by the War Enquiry Commission (1975) and the
Packard Commission (1985). This directive strengthened the role of the JS HQ's command and control of the Pakistani military with chiefs of the staff of army, navy, and air force, still maintain their control of their respected services. Besides the nuclear command and control, the JS HQ provides the control, clarity, mission parameters, objectives, selection of weapon system to nation's armed services to execute the mission and attain objectives. == Branches of the Joint Staff ==
