This is incredibly baffling. How can a tank "get lost and run out of fuel"? The tanks don't have GPS or even a map? They don't have radio connection to some kind of command that know where its tanks are? Like ... how?

I don't even know. This seems like a plausible deniability for desertion or something. "We ran out of fuel, oh well, nothing we can do." Not that I'm complaining, I'd rather get lost and captured than fight for Putin either.
