Ukrainian Forces Stabilize Frontline Near Sloviansk Amid Russian Offensive Shifts
Ukrainian military units have successfully slowed the Russian offensive in the Donetsk region and stabilized the frontline near Sloviansk, though the tactical situation on this sector remains complex, OSINT analyst Clément Molin reported. Ukrainian defensive lines held firm against four advancing Russian armies deployed along a 50-kilometer front following the withdrawal of Ukrainian troops from Pokrovsk and Myrnohrad in early 2026. Molin noted that Russian forces have currently halted their attempts to push toward the western administrative borders of the Donetsk region and the city of Druzhkivka. Despite Russian advances, the situation for Ukraine still looks somewhat better than it did in the spring.
Infiltration Tactics and Strategic Stakes in Dobropillia
Molin observed that Dobropillia holds immense significance for the ongoing conflict because control over the city could theoretically open a path for a Russian advance toward Barvinkove. However, the analyst considers that scenario unlikely due to the strength of Ukrainian fortifications in the area. Meanwhile, senior lieutenant of the Ukraine Defense Forces with the call sign “Alex” stated that the Russian offensive on Dobropillia and the surroundings of Druzhkivka will grind to a halt by the onset of winter.
Intense Urban Combat Persists Across Kostiantynivka
The battle for Kostiantynivka has ground on for over a year, leaving opposing positions heavily intermingled. According to TSN, Russian forces maintain a positional advantage across approximately 50% of Kostiantynivka, while Ukrainian forces hold roughly 15%. The remaining 35% of the city represents a contested zone where neither side holds a clear territorial advantage. Further north, the situation near Sloviansk and Kramatorsk gradually deteriorated throughout 2026, though Ukrainian forces managed to push Russian troops away from the cities in September.
Ukrainian Defenses Expand, Restricting Russian Movement
Ukrainian forces are continuing to expand defensive construction to blunt enemy advances. OSINT researcher Clément Molin mapped out fortification lines built across different periods, noting that yellow lines designate pre-2024 works, orange lines mark structures built in 2025, and red lines indicate 2026 defenses concentrated around Pavlohrad, Izium, Kharkiv, Chernihiv, and Kyiv. Molin added that the Russian military faces a growing disadvantage due to a lack of maneuver room. Having closed in on major urban centers and fortified defensive lines, Russian forces are forced to attempt costly frontal assaults. Meanwhile, Russian forces are advancing in the Donetsk region near two settlements, Rai-Oleksandrivka and Volne, while fighters from the 13th “Khartia” Brigade of the National Guard of Ukraine are already confronting Russian forces in old Soviet gas pipelines near Kupyansk in the Kharkiv region.
