Can't speak about the Chinese, but because of this war in Ukraine the Russians definitely have a very big head-start when it comes to the execution of anything artillery-related, as in I don't think the Americans have had to fight a real counter-artillery fire since at least the Battle of Hue. Maybe the Ukrainians (also pretty experienced by now) will teach them, if they (meaning the Americans) will be open to learn.
As for the the Russians, they clearly shown that spending tons of munitions to make holes in the open fields is not really efficient. [1] Ukrainians on the other hand are pretty successful in counter-battery fire using US (sic!) systems. See HIMARS, for instance.

HIMARS has started to successfully being jammed by the Russians lately [1]:
> Russia has been thwarting US-made mobile rocket systems in Ukraine more frequently in recent months, using electronic jammers to throw off its GPS guided targeting system to cause rockets to miss their targets, multiple people briefed on the matter told CNN.
which probably should have been deserving of its own HN submission.

You "just" get THOR to fire and take them out?
You "just" take out inbound artillery?
I haven't paid attention to them since the First Gulf War, but the abilities and competence of the 101st Chairbourne continue to be renoun and without equal.
