Shaurya is mainly for a tactical nuke role against a time bound target of adversary per what our doctrine allow for?
I mean a conventional warfare, the reach of long range was regarded upto 300-500km. Maybe that has shifted to 1000km now, ie where you can justify using a tactical nuke as preemptive measure against something impending high threat, and almost certainly that needs to be in a very time bound manner because there will be very short turnaround time from intelligence to decision making OODA loop.
Just curious how the forces command could use it and why we do not build a large conventional ballistic arsenal yet despite 3 front situation, instead leaving everything on few agnis deterrence.
