AssessmentModerate confidence

Figures carry their own uncertainty. Population, economic and military-spending data in wartime are estimates, often contested; every figure below shows its as-of date and a confidence grade, and leadership positions reflect the last review date and change without notice.

What this actor is

Ukraine touches the eastern-flank system at a small number of specific points: the supply gateway through south-eastern Poland, air-defence interaction over Poland and Romania when things cross the border, and Black Sea security. Those are what this record covers. The war itself is covered in full by the Ukraine–Russia module and nothing about it is restated here.

A boundary that has to be enforced, not just stated

The easiest way to make this module look complete would be to import Ukrainian records into it. That would duplicate claims across two modules with two review cycles and two sets of dates, and the first time they disagreed the corpus would be wrong in one of them. The interface is described here; the war is linked, never copied.
