Russians have serious logistical problems now. There are Twitter videos of some of their tank crews stuck on Ukrainian roads without fuel and being taunted and asked if they want for a ride back to Russia by Ukrainian passers by.
Also, for what it's worth, Russia used 26 Caliber missiles on a single day in Syria back in 2015.
But they're fighting Ukrainians, not Americans.
The point is, Russia has to be selective, especially since Ukrainian AD is still active.
And even if it is, doesn’t that just mean Russia will move from the quick strike strategy to a more bloody, full assault?
"Ukrainian citizen confronts Russian soldiers after tank runs out of fuel"
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.
I realise that stupid things happen during war, but it’s only a few days in and surely this is the kind of thing they train and plan for.
