Situation Report

Situation Update (UTC)

Key updates since last sitrep

• RF Captures Zemlianyi Yar and Losevka (11:45Z, Kotsnews, MEDIUM): Russian Grouping "North" (128th MSBr, 82nd MSBr) captured these settlements in the Kharkiv region, squeezing Ukrainian forces around the Bilyi Kolodiaz logistics node.
• RF Strikes Kharkiv Fuel and Logistics (11:33Z-11:40Z, Colonelcassad / Операция Z, HIGH): RF "Geran-4" drones and aviation struck fuel tanks in Panyutyne and multiple gas stations/parking lots in Kharkiv city, continuing the pattern of deep tactical interdiction.
• RF Advances in Kostiantynivka (11:44Z, Сливочный каприз, MEDIUM): Geolocated footage indicates RF forces are advancing in residential areas of the Chervonyi district in Kostiantynivka and have raised the Russian flag.
• UAF Confirms Belbek Airfield BDA (11:46Z, БУТУСОВ ПЛЮС, HIGH): UAF GUR confirmed the destruction of an RF MiG-29 and an associated airfield launcher at Belbek airfield in Crimea via drone strike.
• UAF Drone Activity in St. Petersburg (11:40Z, WarArchive, LOW / UNCONFIRMED): Unverified video claims to show Ukrainian drones operating over St. Petersburg. Lacks independent BDA.
• NATO Counter-UAV Exercises Scheduled (11:36Z, Рыбарь, MEDIUM): Russian OSINT claims NATO has scheduled six major exercises in 2026 (including VATT 26 in Latvia) across Eastern Europe focusing on multi-domain counter-drone integration (acoustic, radar, EW, lasers).
• Chernobyl Zone Fire Partially Contained (11:54Z, РБК-Україна, HIGH): DSNS extinguished one 130ha hotspot of a forest fire in the Chernobyl Exclusion Zone on day 10; three hotspots remain active. Radiation levels reported as normal.

Operational picture (by sector)

Environmental Factors: Widespread overcast and precipitation continue to degrade optical ISR, necessitating a shift to thermal and radar-based drone operations. Thunderstorms are forecast in the Donetsk sector.

• Kharkiv / Vovchansk: 26.1°C, light rain showers (100% cloud), 4.1 m/s wind.
• Luhansk / Svatove: 32.3°C, partly cloudy (83% cloud), 3.1 m/s wind.
• Donetsk / Pokrovsk: 29.1°C, overcast (90% cloud), 5.3 m/s wind. Forecast: Thunderstorms.
• Zaporizhzhia / Orikhiv: 27.9°C, light rain showers (100% cloud), 6.3 m/s wind.
• Kherson: 21.8°C, overcast (94% cloud), 4.2 m/s wind.

1. Eastern Sector (Kharkiv / Sumy / Donetsk):

• Kharkiv (Vovchansk / Bilyi Kolodiaz Axis): RF forces are executing a deliberate envelopment of Bilyi Kolodiaz. The capture of Zemlianyi Yar (by 128th MSBr) and Losevka (by 82nd MSBr) severs key segments of the T-2104 rocade. UAF 57th OMPBr, 159th OMBR, and 120th OTBr are bearing the brunt of the defense. RF sources claim UAF morale is degrading, necessitating the deployment of training instructors to the frontline.
• Sumy: RF aviation successfully struck a UAF "Baba Yaga" heavy hexacopter launch site in Khmelivka, indicating RF ISR is actively tracking and targeting UAF deep-strike drone nodes in border regions.
• Donetsk (Kostiantynivka): RF ground elements are pushing through the Chervonyi district. While full city control remains unconfirmed by UAF, localized RF flags and residential advances indicate a deterioration of the UAF defensive line in the eastern/southeastern sectors of the city.

2. Southern Sector & Crimea:

• Crimea: The confirmed loss of a MiG-29 at Belbek further constrains RF tactical aviation sortie generation. RF is likely forced to disperse remaining assets or rely more heavily on glide bombs (KABs) launched from stand-off ranges.

3. Deep Rear & RF Interior:

• Dnipropetrovsk: Kinetic strikes targeted RF locomotives, compounding the logistical friction previously identified in the region's rail network.
• St. Petersburg: Unconfirmed reports of UAF drone incursions. If verified, this represents a significant expansion of UAF's strategic depth targeting.
• Chernobyl Exclusion Zone: Ongoing 130ha forest fire presents an environmental hazard. While DSNS reports normal radiation, the presence of three active hotspots requires continuous monitoring to prevent radioactive plume dispersion.

Enemy activity / threat assessment

• Tactical Envelopment in Kharkiv: RF Grouping "North" is successfully isolating Bilyi Kolodiaz. By capturing flanking settlements, they are forcing UAF into a constrained urban defense or risking encirclement.
• Logistics Interdiction: The use of "Geran-4" long-range drones against fuel infrastructure (Panyutyne) and civilian/dual-use logistics in Kharkiv city demonstrates RF's continued refinement of deep-tactical strike packages to degrade UAF sustainment.
• NATO C-UAV Adaptation: According to RF intelligence assessments, NATO is rapidly institutionalizing counter-UAV tactics. The scheduling of exercises like VATT 26 (integrating acoustic sensors, radar, EW, and directed energy) indicates that NATO views UAF drone superiority as a primary threat and is actively scaling these countermeasures for the Baltic and Eastern flanks.

Friendly activity (UAF)

• Deep Strike Aviation/Drone Ops: The confirmed destruction of the MiG-29 at Belbek highlights the continued efficacy of UAF GUR drone packages against high-value RF air assets. Strikes on RF locomotives in Dnipropetrovsk disrupt enemy rail logistics.
• Heavy Drone Operations: UAF continues to utilize "Baba Yaga" heavy night-bombers from Sumy to strike RF border regions (Belgorod), though these assets remain vulnerable to RF aviation and ISR.
• Strategic Narrative: UAF General Staff claims the liberation of 670 sq km of territory in 2026 thus far. This is a calculated information operation to counter RF narratives of relentless advance and maintain domestic/international morale.

Information environment / disinformation

• Kostiantynivka "Victory" Narrative: RF milbloggers and international propagandists (e.g., MV-Lehti) are amplifying claims of Kostiantynivka's fall and the start of battles for Sloviansk-Kramatorsk. The geolocated footage in the Chervonyi district is being used to lend credibility to these broader, unverified strategic claims.
• NATO "Learning" Narrative: Russian OSINT (Rybar) is highlighting NATO's counter-drone exercises to signal to the domestic audience that the West is adapting, thereby justifying the need for rapid Russian tactical innovation and masking any current deficiencies in RF electronic warfare.
• Chernobyl Fire Management: DSNS is proactively managing the information environment regarding the Exclusion Zone fire, emphasizing containment and normal radiation levels to preempt panic or RF exploitation of a potential environmental disaster.

Outlook (next 6-12h)

• MLCOA: RF will continue to tighten the encirclement of Bilyi Kolodiaz, utilizing artillery and FPV drones to interdict UAF withdrawal or resupply routes along the T-2104. In Donetsk, RF will attempt to consolidate the Chervonyi district in Kostiantynivka.
• MDCOA: RF achieves a breakthrough at Bilyi Kolodiaz, collapsing the eastern Vovchansk flank and threatening the wider Kharkiv defensive architecture. Concurrently, RF exploits localized success in Kostiantynivka to push toward the city center, threatening the Druzhkivka road.
• Decision Points: UAF High Command must decide whether to reinforce Bilyi Kolodiaz to hold the line or execute a phased withdrawal to the next defensive belt to avoid the loss of experienced personnel from the 57th and 120th brigades.

Intelligence gaps & collection requirements

1. Bilyi Kolodiaz Status (CRITICAL): Urgent need for SIGINT and high-resolution SAR/EO to determine if UAF forces are successfully holding Bilyi Kolodiaz or if an encirclement/withdrawal is in progress.
2. Kostiantynivka Chervonyi District (HIGH): Verify the exact depth of RF penetration in the Chervonyi district. Determine if UAF maintains organized defensive positions or if the area is contested/abandoned.
3. St. Petersburg Drone BDA (MEDIUM): Task national technical means or HUMINT to verify if the reported UAF drone flights over St. Petersburg resulted in any kinetic impacts or if it was merely a probing/reconnaissance mission.
4. Chernobyl Fire Radiation Plume (LOW): Deploy independent environmental monitoring assets to verify DSNS claims regarding radiation levels, ensuring no hazardous plume is drifting toward Kyiv or RF territory.
