Just after the Olympic opening ceremonies are over?
Sometime Feb 4-11?
Broad front to the Dnipier? Or down the Black Sea coast to Odessa? Or both?
I'm leaning to a mad dash along the coast.
They've been digging in on that eastern front. It's a lot of depth to penetrate. Once you start, you have to push all the way to the Dnipier.
Probably a lot more casualties that way. Both sides.
A lighting flanking maneuver along the coast. His navy can follow along with the spearhead close to the coast giving cover and support with it's firepower.
Closes all Ukraine's ports and access to the sea. Instantly shuts down Ukraine's imports/exports thus economy and establishes a land bridge to Crimea at the same time.
Given the overwhelming firepower with the fleet providing cover as well, it would be a quick victory, actually probably the least casualties, compared to slogging it out along a wide front.
Seems like a Judo'ey kinda thing Vlad would like.
