1. Brahmos are atleast x10 more expensive compared to the babur. Due to its size India will be significantly limited in how many Brahmos they could launch at once due to the size of their launchers. Only a few SU30mki until now has been structurally modified to carry Brahmos.
2. Also due to its size Radars will be able to identify launch sites. Counter battery artillery/missile/airstrikes would be initiated.
3. Pakistan has been producing the babur since 2005 at around 300k USD per unit
4. Pakistan has a stock of thousands of baburs/raads/nasrs/fateh/A100 and other short range rockets
5. I doubt the Brahmos reliability as its made out to be. Its a remade Soviet Era Yakhont anti ship missile
6. Having a launch site with this many Brahmoses in storage I believe shows the idiocy of indians. A single decent missile from a UCAV would be enough to set that whole place is SMOKE
It would have been much much smarter to have underground bunker sites with underground tunnels/storage facilities. Have a few spread out across the front. Similar to what Iran/China have done.
India has not shown to the guts to escalate the conflict beyond a certain threshold. The next conflict will 99% likely also pan out that way. The last time Pakistan got the last word, the next time the Indians would want to get the last word.
In either case, Pakistan has the options to decimate IAF forward operating bases in the whole North Western front via missiles/rockets alone. From there it will shift to command nodes/SAM sites/Supply bases via a combination of army incursions/ air strikes/UCAVs and armored units. From a strategic point of view even if India were to strike first it would mobilize the majority of pakistans population to take action. Pakistan could exceed India in having more equipment/troops to the front lines at a much quicker rate.
