Russians will eventually take Avdiivka, at far greater cost than Ukraine, then stop, unable to advance further. The same as what happened in Bakhmut. Russia is not attacking places out of operational planning or strategy. They are attacking where there are enough rail lines and roads to concentrate forces to attack. That's it. Russian logistics can not handle more than that.
Social media can take every Twitter or Telegram about every block by block report and turn them into overly academic analyses all they want. The big picture is Avdiivka is 11 square miles, Russia flanked the city on three sides, and it took them two years to take it. That is a pitiful showing by the Russian military.
Russia is willing to take high loses. There is still a limit on what they can take and fight effectively. According to Forbes, Russia lost 10% of its tanks at Avdiivka, at a 12:1 loss ratio, for what is left of the city. Ukraine can afford to trade a pile of rubble for casualties like that.
One more of many Russian Pyrrhic victories.

Thanks for the LAUGH!
