Structure of the Pakistan Army

The Structure of the Pakistan Army can be broken down two ways, administrative, and operational. Operationally the Pakistan Army is divided in 11 Corps having areas of responsibility (AOR) from mountainous regions of northern Pakistan to the desert and coastal regions of the south. Administratively it is divided in different regiments (details below). The General Headquarter (GHQ) of Pakistan Army is located in the garrison city of Rawalpindi in Punjab province. It is planned to be moved to the capital city of Islamabad.

Army headquarters and staff
The Chief of the Army Staff (COAS), formerly called the Commander in Chief (C in C), is challenged with the responsibility of commanding the Pakistani Army. The COAS operates from army headquarters in Rawalpindi, near Islamabad. The Principal Staff Officers (PSO's) assisting him in his duties at the Lieutenant General level include:


 * Chief of General Staff (CGS) — Lt Gen Rashad Mahmood
 * Chief of Logistics Staff (CLS) — Lt Gen Muhammad Haroon Aslam
 * Inspector General Arms (IGA) —
 * Adjutant General (AG) — Lt Gen Javed Iqbal
 * Quarter-Master General (QMG) — Lt Gen Sajjad Ghani
 * Inspector General Training and Evaluation (IGT&E) — Lt Gen Raheel Sharif
 * Military Secretary (MS) — Lt Gen Mazhar Jamil
 * Inspector General Communications and IT (IGC&IT) — Lt Gen Khalid Asghar

The Military Operations and Intelligence Directorates function under the Chief of General Staff (CGS). A major reorganization in GHQ was done in September 2008 under General Ashfaq Parvez Kayani, when two new PSO positions were introduced: the Inspector General Arms and the Inspector General Communications and IT, thus raising the number of PSO's to eight.

The headquarters function also includes the Judge Advocate General (JAG), and the Comptroller of Civilian Personnel, the Chief of the Corps of Engineers (E-in-C) who is also head of Military Engineering Service (MES), all of them also report to the Chief of the Army Staff.

Hierarchy

 * Corps: A Corps in the Pakistani Army usually consists of two or more Divisions and is commanded by a Lieutenant General. Currently the Pakistani Army has 11 Corps.  The eleventh one is the recently raised Army Strategic Force Command (ASFC), responsible for bearing the national strategic and nuclear assets.  Initially a Division, but then raised to the status of a Corps.
 * Division: Each division is commanded by a Major General, and usually holds three Brigades including infantry, artillery, engineers and communications units in addition to logistics (supply and service) support to sustain independent action. Except for the Divisions operating in the mountains, all the Divisions have at least one armoured unit, some have even more depending upon their functionality.  The most major of all ground force combat formations is the infantry division. Such a division would primarily hold three infantry brigades.  There are 19 Infantry divisions, two mechanised divisions, two Armoured Divisions and 2 Artillery Divisions in the Pakistani Army.
 * Brigade: A Brigade is under the command of a Brigadier and comprises three or more Battalions of different units depending on its functionality. An independent brigade would be one that primarily consists of an artillery unit, an infantry unit, an armour unit and logistics to support its actions.  Such a brigade is not part of any division and is under direct command of a corps.
 * Battalion: Each battalion is commanded by a Leiutenant Colonel and has roughly 600 to 900 soldiers under his command. This number varies depending on the functionality of the battalion.  A battalion comprises either three batteries (in case of artillery and air defence regiments - generally named Papa, Quebec, Romeo, and Headquarters Battery) or four companies (in case of infantry regiments - generally named Alpha, Bravo, Charlie, and Delta - and other arms excluding armored units that are organized into squadrons) each under the command of a major and consisting of individual subunits called sections (which are further divisible into platoons and squads).

Corps
There are 11 Corps located at various garrisons all over Pakistan.

Independent Brigades
Please add information!!

There are seven Independent Mechanized Infantry Brigades, eight Independent Armoured brigades, 4 Artillery Brigades, and nine Engineer brigades. These include 105 Independent Brigade Group in XXXI Corps, 111 Independent Infantry Brigade at Rawalpindi with X Corps, 212 Infantry Brigade at Lahore with IV Corps and 105 Independent Infantry Brigade under V Corps. Nine independent signal brigade groups are also present (one in each corps).

Former formations
Eastern Command was a Corps level formation in the former East Pakistan consisting of 14th, 9th and 16th Infantry Divisions. All three were re-raised after the war and exist today. 14 ID pretty much did not fight, since it was heavily Bengali and 6 of its battalions deserted when the operation began.

36 ID and 39 ID were raised to command the Paramilitary troops and a few loyal battalions. Were later reinforced with a couple of other battalions each. They were not re-raised after the war.

Administrative Structure
The Pakistani Army is divided into two main branches, which are Arms and Services.
