There is a barren desert here, and "empty space". The traditional planned scenario is for PA to give ground in this area. If you look at satellite pictures, you will see that the defense lines that PA has prepared is way back, ceding desert territory in case of an attack.
This is where Nasr is planned to be used. What I am saying is that CAS would be very effective as well, and would be a conventional deterrent rather than Nasr.
You have to understand that PA is not giving away any valuable flatlands. They are giving away (and this is their traditional doctrine for the last 50 years) land which is largely not populated, and mostly impassable.
You see, this desert land is not like other deserts. It is a desert that has a very unique kind of sand. The kind of sand that bogs you down. Doesn't allow free movement of armor. Creates bottleneck of troops and armor.
Flat desert. Nowhere to hide. bottlenecked and bogged. Inside enemy territory (for the Indians).
And then a flight of F-7PGs and Mirages show up, dropping precision munition and cluster bombs.
Think of the impact of this. It would be devastating. Think of their supply lines stretching through this inhospitable desert.
You have to have vision to see the benefit in this.
Perhaps
@Signalian would be able to add to what the PA is facing in this terrain. It is a very unique terrain and only professional soldiers who have been in this terrain understand it.
Now, future armored warfare against "Cold Start" is expected to take place not only in the desert but the land between the plains of punjab and the desert. You see, the desert does not end abruptly nor the plains begin abruptly. Between this terrain, and in the desert, it is expected that someday, an Indian integrated battle group could show up. PA has been preparing for this in a myriad of ways. Including with both conventional and unconventional Nasr.
What I am adding is that in such a terrain, CAS would be immensely effective as a conventional deterrent. Whether one is lobbing precision munition or cluster munition. One does not need long range for this mission, nor long loiter time.
Even if you lost 10 percent or 20 percent of your CAS aircraft, if you could destroy 30% of enemy armor, you would have achieved enough to have made it worthwhile x 3 times over.
One has to understand that such an armored thrust would be the tip of the spear for India. Damaging that tip would be of vital interest to Pakistan.
