In the early hours of September 16, Ukrainian forces extended their long-range campaign deeper into Russian territory, striking both a military airfield in Rostov Oblast and an oil refinery in Yaroslavl. These twin strikes — one against the machinery of war, one against the fuel that sustains it — reflect a deliberate and patient strategy: not to win a single battle, but to erode the foundations upon which Russia's war effort rests. The pattern of repeated, targeted strikes on the same installations suggests less a war of moments than a war of attrition waged from the air.
