Okay, let's say that they are assembling troops and equipment [View all]
at Brest. Brest is in Belarus at the border near Poland. It is opposite to a city called Terespol, which is in Poland, on the other side of the Bug River.
If Russia took control of the Bug River, it would have a waterway going through Poland, but also connecting up to Ukraine. The river lets out in the Baltic Sea. It is said to be navigable for the most part, but I don't know what size ship.
Suppose they practiced that pontoon bridge deployment to cross the Bug River? The Bug River acts as a border between Poland and Belarus. Why would they start stocking up troops and equipment on that spot in the border? It isn't convenient to Ukraine; it's convenient to Poland.
If they started an attack there, and also from Kaliningrad, and also from the Ukraine border, then they'd have them on three sides.
