I'm pretty sure the same video was posted here before, but I couldn't find with a quick search and on that was info that the vehicles would've been self propelled artillery. I'm not expert either and from video that's pretty hard to tell for sure.

That being said, Ukraine seems to use pretty heavy firepower against "low value" targets quite often which might feel like overkill/wasteful, but they seem to know what they're doing so I'm going to just assume that they know what they're doing and wish that Ukrainians get their peace sooner than later.

iirc from the last time it was posted these were 2S9 Nona self propelled mortars. The Russians are losing their main 152 mm self propelled artillery at a (for them) alarming rate, both from wear and tear of the barrels as well as losses from Ukrainian fire, so they have been forced to use these mortars more and more, but they have shorter range than the artillery and thus much more prone to counter artillery.
