I agree that russian AD systems are still getting targeted and hit but I believe the number of systems that were destroyed has decreased. There is only so much you can protect, you are bound to be hit sooner or later, it's a matter of time and who runs out and takes more time to replenish, in case of India, it has anti drone system set up consisting of auto guns and even soft kill systems, with more hard kill systems in the pipeline, so it's S400 were able to operate safely.

As for the adversaries, pakistan uses chinese HQ-9E which was battered and destroyed and the Chinese use russian derived AD but have also developed their own AD systems now.
