IV Corps

IV Corps, headquartered at Lahore, is responsible for the sector from Narowal to Sulemankie. The IV Corps consists of at least two holding Infantry Divisions, as well as one independent tank brigade, and one or two other brigades, which may include one independent infantry brigade and/or an independent artillery brigade.

According to some reports, as of early 2001 the 40 Infantry Division was stationed at Okara under IV Corps.

At the time of the 1965 war with India, Pakistan had only one corps HQ [I Corps at Mangla] with plans for a new IV Corps (at Lahore). IV Corps was raised after the 1965 War.

On 31 August 2000 Gen. Pervez Musharraf transfered Lt. Gen. Mohammad Aziz, a Kashmiri, from the post of the Chief of the General Staff (CGS) in the GHQ at Rawalpindi to that of GOC, 4 Corps, Lahore.

In mid-October 2001 Pakistani President General Pervaiz Musharraf re-shuffled several key security positions. Lieutenant General Mohammad Aziz Khan, an "Islamic soldier," was "promoted" as a four-star officer to the largely ceremonial post of Chairman of the Joint Chiefs of Staff Committee. Gen Aziz was the IV Corps commander in the strategically vital border city of Lahore.
