Key takeaway

ISW reads the 1,000km front as frozen, with Russia paying heavily for ground it does not take.

The Institute for the Study of War (ISW) judged the roughly 1,000km front essentially static on 22 July, with Kostiantynivka still Russia's unmet main effort and net Russian gains a fraction of last year's 1. ISW is a Washington research group that publishes daily open-source battlefield assessments, and its maps are a primary independent reference for Western governments. Kostiantynivka is the fortified Donetsk city anchoring Ukraine's defensive line, the last major position before Kramatorsk.

Ukraine has found no trace of the Donetsk advances Valery Gerasimov, Russia's most senior general, claimed on 18 July . The gap between the claim and the geolocated reality is the point: Moscow is asserting captures on a line that independent trackers read as barely shifting.

ISW put the Kostiantynivka loss ratio at three Ukrainian dead to 53 Russian, so the fortress-belt defence keeps imposing a steep price on each Russian push even where the map holds. That arithmetic is why the decisive contests have moved off the battlefield: a static front that favours the defender removes the incentive for either side to gamble on manoeuvre.

Deep Analysis

In plain English

The Institute for the Study of War, a Washington research group that tracks the conflict daily using satellite imagery and open-source reports, assessed on 22 July that Ukraine's roughly 1,000km front line has barely moved. Kostiantynivka, a fortified Donetsk city Russia has been trying to capture for months, remains uncaptured. Russia's own chief of staff claimed new territorial gains days earlier, but independent analysts say they cannot confirm them.

Deep Analysis
Escalation

ISW assesses neither side currently holds the reserves for a decisive breakthrough, meaning the static pattern is likely to persist rather than resolve toward either side in the near term.

What could happen next?
  • Meaning

    A static front with Russian gains far below last year's pace suggests the war's centre of gravity has shifted from territory to attrition and infrastructure strikes.

UKMTO logged six armed men boarding a tanker 136 nautical miles east of Al Mukalla on 20 August and redirecting it toward Somalia. A vessel steered toward the Somali coast reads as an attempted seizure, a distinct hazard from the stand-off strikes the same lane has seen before.
