Ukraine has very few Oplots (probably ~10 of the T-84U Oplot and ~5 BM Oplot-M). By far the most numerous tank they use is the T-64B/B1/BV/B1V family, along with ~100 BM Bulats (a.k.a. T-64BM), several hundred T-72A/B/AMTs, and T-80BVs. T-80BVs are primarily used by Marine (Naval Infantry) units. That is why you see them mostly lost in Mariupol and in the southern front.

Well, according to Chobitok et al. in their 2016 book on the T-64 tank, 70% of Ukraine's armoured vehicle casualties photographically documented during the 2014/15 stage of the Donbas War were from tube/rocket artillery. The remaining 30% were abandoned or non-combat losses. Scenes like this, the aftermath of a Grad barrage on a field camp, were not uncommon. I would hope the Ukrainians have learned their painful lessons and put them to use in this war. As far as I can tell, at least some of them do try to do that? Like in the video you posted. On the other hand, some don't. No idea why, but the truck being nearby suggest they are prepared to move if needed?
