The only way such Artillery units make an impact is if these area are protected by a SAM , made in Pakistan and network of radars that protect from Ariel threats so these ground units can maintain point attack and prevent progress of enemy units on grounds.
With out a proper SAM system to protect these Military units a column of 2-16 Helicopter gunships can disrupt the function of these units on ground
The raw guns / artillery are just too crude of weapon out of place and reminder of WW2 level weaponry
With out radars & Missile systems , the Artillery units are vulnerable
Artillery bombardment is only impactful , if it itself has ample protection from Air
- Since Pakistan does not have Gunship helicopters
- Since Pakistan does not have proper locally build Radar & SAM system
In a real conflict the modern smart bombs would make short work of artillery units does not matter if its 100 units or 1000 Units as these would be sitting ducks on ground
Also mobility units also need improvement
While it may be questionable if we have ability to transport these over mountains or tight road areas but still we need some of these babies
