The Russians haven’t even been able to bridge creeks and swamps the last few months. How in the world do you expect them to span a kilometer wide stretch of river with pontoon boats?
And your idea of them using fairies is fanciful because that could work for small amounts of supplies and for small numbers of troops. But they’re not gonna get heavy equipment across that river in small boats.
Yes of course.....
BTW, it’s ferry’s.
