They are having to supply fuel, food and ammunition to 200,000 men over a 500 Km distance in hostile territory. You would need a fantastic logistical operation to be able to support that even in your own country.
"Ukrainian citizen confronts Russian soldiers after tank runs out of fuel"
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.
And even if it is, doesn’t that just mean Russia will move from the quick strike strategy to a more bloody, full assault?
