Toplines
Ukrainian officials warned that the Russian military command is regrouping and reinforcing its troops in western Donetsk Oblast, likely ahead of a major offensive operation. Ukrainian Dnipro Group of Forces Spokesperson Lieutenant Colonel Oleksiy Belskyi reported that the Russian military command is concentrating significant forces in Donetsk Oblast and that the most intense fighting is occurring in the Pokrovsk direction.[1] Belskyi stated that Russian forces are now accumulating significant numbers of drones and heavy armored vehicles in the area after failing to seize Pokrovsk and Myrnohrad during Summer 2025. The Ukrainian 7th Army Corps reported that the Russian military command recently redeployed experienced naval infantry units to the Pokrovsk direction, indicating that Russia is preparing to re-intensify assaults in the area.[2] The Ukrainian 7th Army Corps reported that Russian forces began leveraging infiltration tactics with small teams with the aim of getting as close as possible to Ukrainian drone and artillery positions, overextending Ukrainian forces, gaining footholds in forward positions, and expanding the contested “gray” zone. The Ukrainian 7th Army Corps noted that Russian forces intensified offensive operations on the flanks of Pokrovsk using armored and motorized vehicles in an effort to interdict ground lines of communication (GLOCs) and envelop Pokrovsk. The Ukrainian 7th Army Corps reported that the Russian military command remains committed to seizing Ukraine’s fortress belt, which consists of Slovyansk-Kramatorsk-Druzhkivka-Kostyantynivka and forms the backbone of Ukrainian forces’ defense in Donetsk Oblast. A senior non-commissioned officer (NCO) of a Ukrainian brigade operating in the Siversk direction reported that Russian forces are conducting troop rotations in the area and that Ukrainian forces anticipate that Russian forces will soon conduct intensified offensive operations.[3] The NCO noted that the Russian military command is pressuring Russian units to advance during Fall 2025, given that Russian forces did not achieve their given objectives during Summer 2025. The deputy commander of a Ukrainian battalion operating in the Kramatorsk direction also reported that Russian forces are building up their force presence in preparation for future assault operations in the Kramatorsk area and that the Russian military command has deployed unspecified naval infantry units to the area.[4]
