The Ukrainian command has released a total count of Russian losses in the quest of subjugating Avdijivka.
If I remember correctly, it was (rounded)
48K troops
nearly 1100 armored vehicles (slighly under 300 tanks)
250 arty
5 planes.
For a city that had less inhabitants then they lost troops.
I assume the battle will continue to be a retreat battle until the prepared fortification lines are reached, which will hopefully stop the Russians.
To put it into perspective, Ukraine has only 1000-1500 tanks active in the whole army, and about 2000 overall. Or on the other side, that is 5% of Russias total tank losses in this 2 year long war, in one place and 3 month - or, at this rate, 1/3 of total losses mathematically.
