This is the only one I know of. Maybe there is something else to compare it to in order to somewhat determine reliability of the data, but I know of nothing else. Browse through his Twitter account and see what else you can dig up. I only know that the gap in his numbers has been closing in as of late, which was quite significant in the beginning, but also somewhat follows reports from the front, I guess.
Edit: as for your expressed purpose, note the difference in numbers for infantry mobility vehicles.
thanks for the link, I saw it once but never found it again before you pointed it out.
So, here is my Extremely Dubious Attempt to Distort Statistics:
UKR has suffered ~250000 PAX losses to date according to various entities (several DoD, DuPuy, etc). If we assumes that PAX losses scale to tank losses (I picked tanks just to draw a line in the sand, see Numbers, Prediction and War) then the UKR PAX losses since the counter offensive are the same proportion to the tank losses.
Oryx puts total tank losses at 626, while the aforementioned link has 59 tank losses since the start of the UKR offensive.
59/626 x 250,000 = 23,562 PAX losses.
Of the losses,
4712 KIA
4712 permanently out of service
4712 returned to duty within a few days
9424 retuning to duty over 2 months
Given the wide range of estimates about the UKR forces used in the offensive, I cannot say what this means in terms of attrition of those units.
So thats my Completely UnDefendable Attempt at Prediction.
