## Prediction

Within seven days, Russian offensive operations in at least one active sector of Donbas or Zaporizhzhia are likely to show measurable slowing, as repeated Ukrainian strikes on refineries, depots, and Crimea’s supply routes create localized fuel and ammunition bottlenecks. Units will increasingly rely on ad hoc trucking and longer supply lines, raising vulnerability to Ukrainian interdiction and drone attacks. This constrains Russia’s ability to conduct simultaneous large-scale assaults and may force a tactical shift towards defensive fortification and more stand-off fires. Confirmation would be credible reporting of reduced sortie rates, delayed assaults, or fuel rationing in specific brigades; denial would be evidence of sustained or increased Russian attack tempo despite infrastructure damage.

## Drivers

- Ukraine’s documented strikes on Saratov refinery, Rostov depots, and Caspian basing points
- Reports of Crimea fuel crisis tied to logistics disruptions
- Trend of Ukrainian UAV attacks on the P-280 highway and land corridor
- Emerging trend: deep‑strike attrition phase of the Ukraine–Russia war
