100k FPV would last a week in Ukraine. (Accounting for use by both sides). Pakistan and India are not Ukraine or Russia and have the ability to field more "cannon fodder". What will break us, especially Pakistan, is not damage but cost.
The only downside for India is that this kind of warfare suits the conventionally weaker side. It's an equalizer of sorts. It's India not Pakistan who has cold start doctrine and these deep arrow armoured strike corps attacks planned.
Back to cost, That's why buying off the shelf drones is unwise and if Merküt is the cheapest most hassle free (supply chain wise) FPV we can get our hands on, cheaper than our own, then that's a problem for us that we have not sorted out supply chains for our own designs.
Anyway, even though this deal sounds like kickbacks scheme to me, something is better than nothing. The deal was signed early this year. I hope we see some Merküts in action against the terrorists and afghans. They make good training dummies.
