As much as I dislike the Army on how they are treating the political system, Pakistan Army specially its ground troops are juiced up on War experience, in concentrated front PA can and will decimate India, Plus PA can mobilize its troops way faster than India but of course IA advantage comes from their numbers, they can open multiple fronts which will spread the PA thin and thus effecting the advance, If a War is fully break out first week will be much more deadly for India than Pakistan and after a week/10 days Pakistan will be in trouble.
