War in North - West Pakistan order of battle The North - Western Contingent order of battle ( NWPORBAT ; officially order of battle is known as " Tri - services framework ( TSW ) " ) , is the comprehensive deposition and systematic structure of the unified Pakistan military forces in tackling down and controlling the insurgency in Western Pakistan . The deployments began in 2002 after the U . S . invasion of Afghanistan in 2001 in a response to the deadly terrorist attacks in New York , United States . This article lists deployed unified military units under the command of the Joint Chiefs of Staff Committee ( JCSC ) which controls both combatant operations and reconstruction efforts , which is often led by the National Reconstruction Bureau ( NRB ) . Since 2002 , the number of troops stationing and circling increased to keep the momentum and pressure on the insurgent groups laying militant attacks on Pakistan . In 2008 , Chairman joint chiefs General Tariq Majid submitted his report on new deployment and formations under title as " Tri - services framework " , to Prime Minister Yousaf Raza Gillani which was approved by the Prime minister . Deployment of the military forces . After the 9 / 11 attacks on the United States , the U . S . military responded with an large invasion of Afghanistan in 2001 . Initially , all Pakistan Army troops were mobilized in different military formations and deployment continued in all over the country during this period , under the command of Chairman joint chiefs General Pervez Musharraf , also self - appointing President at that time . After laying discussion principle Joint Chiefs of Staff Committee , the XI Corps ( roughly ~ 60 , 000 men ) was deployed under the command of Lieutenant - General Alijan Aurakzai in North - western . Other formations were rested in eastern , southern , and the northern borders of the country . By 2004 , additional battalions were stationed by General Musharraf to help curb infiltration into Pakistan through its porous border . On 7 October 2004 , Musharraf approved the appointment of his close aide , General Ehsan - ul - Haq , who superseded seven colleagues who was brutally criticized by the media . The appointment was highly controversial and political since Admiral Shahid Karimullah , Chief of Naval Staff , was the senior - most four - star officer in the armed forces . After becoming the chairman joint chiefs , General Ehsan - ul - Haq oversaw the ground troops deployment of army only , while the air force and navy were kept out of the region . The strategy proved to be wrong as the violence spread out all over the country , and the army was increasingly in great pressure from the militants in 2004 - 07 . In 2007 , chairman joint chiefs General Ehsan - ul - Haq admitted the only ground troops deployment was wrong as the " Waziristan truce went wrong " . President Musharraf ordering the highly controversial and criticized military action , " Silence " , to take over the Red Mosque complex plummeted Musharraf and General Ehsan ' s support . In 2007 , President Musharraf approved the General Tariq Majid and General Ashfaq Parvez Kayani ' s appointment to four - star appointment . Keeping aware of the situation , General Majid began studying the new deployment of Pakistan armed forces . After Musharraf was ousted from the presidency in a threat of impeachment movement , General Majid submitted his studies to Prime Minister Yousaf Raza Gillani and stressed out on the need to strengthen the tri - services framework . The new order of battle now known as , " tri - services framework " , General Tariq Majid strongly emphasized to harmonize individual capacities of the services so that efforts are synergized within a framework of jointness and inter - operability to meet present and future challenges . Since 2008 , the combined formations of Pakistan military has over a hundred thousand troops in the region . From open sources it seems that 4 Pakistan army divisions , assisted by the PAF and the navy , are involved in the operation , with a JS HQ coordinating their efforts . They appear to be two regular and two heavy infantry divisions Frontier Corps operates under a separate command , but its units are often parceled out to the Army . The Corps in the region , the XII Corps , usually has 2 infantry divisions , it has received from what can be gleaned from open sources two additional divisions , one from Multan ; the 14th , and another from Kashmir ; the 23rd .
