path to GB is almost entirely mountains, we will have to neutralize paki artillery and command posts before infantry can move in, which require either IAF to establish air superiority in the area ,which is not possible, or other way is we pound pakis with missiles, ideally with pralay and LR-LACM when it ready.
The real issue here is we lack fire power to do an "big offensive", we do have fire power for defending or retaliation and probably to push back pakis a little bit, but entering and holding territory is whole another task. We can't hold territory with current amount of artillery pieces, there is also issue of our infantry, these areas being unprotected , we need tons of MRAPS, IFV to move around in mountains forest and avoid ambushes, we need anti-drone measures for FPV drones and whole a lot that I probably don't even know.
