Guys just take a chill pill.
Have an intellectual debate and not blind nationalism.
I will start:
Basically, Pakistan has 10 Corps along with Strategic Corps for Nuclear Weapons.
Its Main Strike Corp also known as Army Reserve North is composed of I Corp and II Corp. In an event of War Indian plan is to tie them them down in a battle of attrition since a war of maneuver in Punjab seems very unlikely.
In Kashmir, Pakistan has X Corp, which will be reinforced by XI and XII Corps from the West along with Northern Area Corps. They will be entrenched in a defensive formation along the LOC.
Pakistan's 2nd Main Strike Corps is known as Army Reserve South and is composed of IV, XXX and XXXI Corps. The V Corp will function as a strategic reserve. It is here around Southern Punjab/Northern Sindh where India can wage a war of maneuver that it will attack with their two main strike corps and will simply overwhelm the Pakistani Corps.
This is Pakistan's Army biggest weakness.
And the article is exactly right, in 3-4 weeks, the Pakistani Army will crumble under the immense weight of an Indian Offensive.
What Pakistan needs to do is this, IMO:
1 - Create a General Reserve Army of 2 Corps (2 Mechanized and 4 Infantry Divisions and 8 Independent Brigades). Around 120,000 men, 750-1,000 Tanks and supporting artillery, mortar, anti-aircraft and anti-tank brigades. This Army would only be activated in a time of war with India. Its aim would be to plug the hole should front-line troops of Army Reserve South crumble under the Indian onslaught.
2 - Add another Corp to the Sindh Command and move the Sindh Command from a Reserve Army to frontline troops. In a time of war, the Sindh Command composed of V Corp and another Corp will give India pause should it chose to launch an offensive in Southern Punjab.
In total, Pakistan needs to increase the size of its Army from 550,000 to about 600,000 active duty men along with increasing the Reserve Force from 528,000 to 650,000 men along with 1,000 - 1,500 Tanks, and numerous anti-tank, artillery and anti-aircraft units.
This should be enough for Pakistan to wage an effective defensive war with India and prevent any territory from falling into Indian Hands.
