There are reports that Russian tank drivers are selling the tank's fuel to locals and getting drunk on the proceeds, then abandoning their tanks e.g. [1]
although I can't verify the veracity of these stories.
Just to say for anyone skimming through, that story is from before the war was declared, maybe they really believed they were there for exercises. Still, embarassing.
They can drink and hide and wait for the other Russian oligarchs whose wealth is being seriously threatened to remove their foolish leader and stop the idiotic war. That is more sensible than risking your life to kill your neighbor, all for the benefit of nothing but making a little man feel powerful.
that's a funny story but I have my doubts that superior officers have such little communication with their charges that something like that would happen without said tank occupants being court marshalled immediately
