The ruskis are good in terms of firepower and capability to overwhelm but holy fucking shit are they bad at planning. The goal of an invasion is to control the most amount of area while keeping the least amount of perimeter in the boundary with the enemy so ideally the boundaries should be the arches or circles or atleast somewhat curved, never leaving spikes because those maximize perimeter and minimize area.

Do you think they're being sloppy because they're confident they'll take the capital anyway? The boundary's hausdorff dimension is crazy stupid.
