Sir, I respectfully disagree. Our doctrine is of Offensive-defensive. There are many factors which lead to such a doctrine, first is our numerical inferiority to fight a battle of attrition, secondly international pressure will force both sides to end hostilities within at most two weeks and thirdly both countries have had more than 50 years to study and work on their defence thus very few avenues of approach are left (Which both sides will try to exploit).
Also it would be unfair to say that we are not ready to cross the border,infact we might be tge first ones to do so because of the nearness of our strike formations to the border as well as shorter mobilization time of PA as compared to IA. All of our regional commands have strike assets which are as follows
-Northern command has 34 light infantry Division and will also be supported by 1×inf div from 11 corps, Peshawar.
-Central command has the 1 strike corps(Army reserve north), Mangla with 6th armoured div, 17 and 37 infantry div( and may as well 19 inf div)
- Southern command has II corps(Army reserve South) with 1st armd div and 14 inf div. While V corps Karachi also has 25 mech div.
Another point to note here is that Pakistan army raised a whole new formation i.e 30th corps, Gujranwala so as to relieve 1 corps of any defensive ops. This 31 corps will be responsible for overall defence of Gujranwala salient so that 1 corps will be purely and solely responsible for offensive into the Indian Territory.
Similarly 26 mechanised div has been raised in Bahawalpur with 31 corps so that II corps won't have to commit its 1st armd div in central/southern punjab for def ops and instead any armoured thrust will be met by 25 mech div, 40(presumably mech inf) div and 35 inf div. It may also be supported by 1×inf div from 11 corps.
So we have dedicated assets responsible for offense inside India.
Can you blame them? Our military posture and doctrine isn’t really offensive based to begin with, to think of crossing the border is a long shot. From the way things are looking Pak Army thinks it’s best to hold the line and come to a settlement through the conflict.
