The Russia Rear theater tracks conflict activity physically located on Russian territory outside the Ukraine bounding box: Ukrainian long-range drone and missile strikes on military-industrial facilities, oil refineries, airfields, ammunition depots, and rail infrastructure across European Russia and the Urals. Coverage extends from Bryansk and Belgorod oblasts deep into the Russian interior as far east as the Urals.

Events in this theater are defined by location on Russian soil, not by actor. The Ukraine war is the proximate cause of virtually all current activity here, but the theater captures the geographic footprint of strikes that fall outside the Ukraine bbox. Confidence scoring reflects the corroboration available from OSINT geolocators, Russian regional Telegram channels, and Ukrainian official statements.
