Operational Tempo: High intensity combat operations persist across the front, with 111 combat engagements reported on April 9. The primary axes of engagement remain Pokrovsk, Lyman, Toretsk, Kupyansk, Siversk, the Kursk/Sumy Border region, Novopavlivsk, Huliaipole, and Orikhiv. The Institute for the Study of War (ISW, Apr 9 assessment) confirms ongoing Russian pressure and advances near Kupyansk, Lyman, Toretsk, Pokrovsk, western Zaporizhzhia Oblast, and the Kursk/Sumy border area, while also noting Ukrainian advances on the Pokrovsk and Toretsk axes.
Russian Offensive Posture: Russian forces maintain a high operational tempo, characterized by extensive use of Guided Aerial Bombs (105 KABs reported used on April 9, including claimed FAB-3000 use near Miropolske/Petrushevka, Belgorod Oblast), massed artillery (nearly 5000 shelling incidents), FPV/Kamikaze drones (1068 used), Geran-2 (Shahed) strikes (Kyiv, Kharkiv, Khmelnytskyi Oblasts targeted overnight Apr 9-10), and ground assaults. Russian sources claim strikes against 149 Ukrainian concentration areas and facilities allegedly involved in missile/UAV production. Commander-in-Chief Syrskyi previously assessed heightened Russian activity as indicative of offensive preparations towards Sumy and/or Kharkiv Oblasts. A potential new helicopter-type UAV was reported near Naro-Fominsk (Moscow Oblast), requiring verification.
Territorial Control & Claims (Incorporating ISW Apr 9 Assessment & Recent Claims):
- Kursk/Sumy Border: Russian forces confirmed control of Huyevo (Kursk Oblast), with visual confirmation of destroyed Ukrainian M2 Bradley IFV and BTR nearby. Intense fighting and Russian clearing operations continue near Oleshnia, Hornal (Kursk) and Loknya (Sumy). Russian forces reportedly reached the Gornal line, preparing further assaults towards remaining UA-held villages. The status of Basivka (Sumy Oblast) remains contested (RU claimed capture Apr 6; UA Border Guard denied Apr 6, confirming combat; RU sources claim UA counter-attack attempt repelled Apr 9-10). NEW CLAIM: Russian sources (citing official military correspondents) claim capture of Zhuravka (Sumy Oblast) by Ussuriysk paratroopers (Apr 10). ISW confirms Russian advances in the border area (Apr 9). Russian state sources (TASS) made highly likely exaggerated claims of evacuating "tens of thousands" of deceased Ukrainian soldiers from the Kursk border area.
- Kupyansk Axis: ISW assesses Russian advances near Kupyansk (Apr 9). High intensity reported by Ukrainian sources (via RU channels) near Kamyanka (Apr 10).

ISW confirms Russian advances near these locations and towards Bohatyr (Apr 9), noting geolocated footage of RU advances south of Bohdanivka. NEW CLAIMS: Russian forces claim capture of 4 strongpoints and 2 heights on the Bohatyr-Otradne line, creating conditions for an assault on Bohatyr (Apr 10). Russian sources previously claimed a breakthrough 1.2km deep / 2.2km wide near Dniproenerhiia–Otradne and advances towards Komar/Otradne and Bohatyr. Civilian evacuations reported from Velyka Novosilka (TASS, Apr 10).
