Russian Army Scores Tactical Advances in Kostiantynivka
According to a report from the U.S.-based Institute for the Study of War (ISW), relayed by Glavcom, Russian troops have made tactical progress in and around Kostiantynivka. This area has become one of the key focal points for their offensive operations during the spring and summer of 2026. The campaign to capture the city began in August 2025, when Russian forces started laying the groundwork for a direct frontal assault.
As of June 6, Russian occupiers had replenished 80% of the units involved in attacks on Kostiantynivka. ISW reports that Moscow has concentrated at least one full army and an army group in the vicinity, along with elements from several other armies to back the offensive against the city.
“In late summer and early fall of 2025, Russian troops began setting the stage for a frontal assault on Kostiantynivka. They combined a sustained campaign of battlefield air interdiction (BAI), tactical blocking measures, infiltration operations, and massed small-unit attacks to inch forward.” – Institute for the Study of War (ISW)
Frontline Situation
Russian military leadership appears to have shifted its priority to capturing Kostiantynivka after encountering difficulties advancing on Sloviansk. The area of responsibility for Russia’s Western Group of Forces stretches from the Kupiansk axis to the Lyman axis. This group likely lacks the combat capability to mount a coordinated push on Sloviansk while simultaneously sustaining offensive operations in Kupiansk and Borova.
Over the past 24 hours, the following activity was recorded:
- 251 combat engagements
- 100 airstrikes
- 292 guided aerial bombs
- 9,293 kamikaze drones
- 3,248 shelling incidents against settlements and positions, including 38 strikes from multiple rocket launcher systems
The situation in Kostiantynivka highlights an escalation of hostilities in eastern Ukraine, where Russian forces are trying to solidify their foothold. Given the heavy losses and challenges they face in other sectors, the strategic importance of Kostiantynivka could shape the conflict's next phase. It is now critical to monitor how both sides adjust their tactics and how the international community responds to these developments.
While Russian forces have made notable tactical gains near Kostiantynivka, it's important to consider that this comes amid the slowest advance rate recorded since October. Understanding the broader context of the Russian military's operational challenges can provide valuable insights into their strategic priorities.
