Krasnopol fired from Msta
That's brigade artillery, which in the Russian case is to a significant margin equipped with 152/47 SPGs.
Ukrainian brigade artillery is mostly 2s1 and towed guns (105,122). Some of the lucky brigades have M109s( /39).
Excalibur fired from AHS Krab?
That's corps/army artillery, a whole level higher. Together with all other western-supplied 155/52 systems, as well as 777, 2a36, and 2s7. This group also includes 220, 227(corps) and 300(army) rocket fires.
Far,
far rarer thing on the whole front - for the Ukrainian side. Just not enough available supply.
Also, Excalibur supply amount is limited - if for the sake of argument you limit your SPGs to firing just them - they are as good as self-suppressed, and can work only as [relatively weak] tactical precision fires. But this is more about pure range metrics comparing(largest numbers out of context) - i.e. your whole understanding of how - and where - artillery is deployed is completely flawed.
Ideas about M777 used to target the high value Russian assets behind the front is especially peculiar.
That's what they're in fact often used for - and the reason so many of them get targeted. As are all the others, because that's that they're for, not for destructability metrics(where AHS Krab leads among /52 systems - and not because it's bad, but rather because it's
good - there are enough of them available to risk them, and Ukrainians are often enough sure that it won't break w/o enemy interference like pzh2000 does)
There are just not enough /52 SPGs around at any given time - typically just a few per single battlefront. And when they're available - the question of long-range ammo - and the question of
what to engage with it - always kicks in.
I think it's worth reinstating here at least once:
(1)longest available ranges(guided) matter, and matter a lot, but:
(2)longest available dumb ranges matter, too - because suppression fires are done with multiple shells, single shot doesn't suppress(you could see a couple of days ago what unsuppressed strongpoint does to a mechanized company)
(3)longest available dumb(not rocket-assisted) ranges matter too, because those are just heavier, far more precise(predictable) and more destructive;
but finally:
(4)unless absolutely unavoidable, the absolute majority of fire missions are done not with long-range shells and not even on full charges. Spare your guns, especially when you don't produce barrels. If you want to hit anything with at least (3).
You have like 250 hidden videos of lancets destroying Leos and other stuff?
Well, close to 200 videos and counting during the Ukrainian offensive, and that's not counting either other videos (artillery, rocket, airstrikes) nor taking into account the whole CB thing. That's for artillery, b/c for
leos and other stuff the main killer/video provider aren't them, it's that Kamov rotary thing.
