Russia–Ukraine War: The Ground War & Front Lines
Assessment
The ground war has tipped. ISW assesses Ukraine has 'largely halted' Russia's 2026 spring–summer offensive (2 Jun); Russia captured just 14 km² in May — its lowest monthly gain in three years — despite a 37.5% jump to 7,000+ assaults, while DeepState and Syrskyi say Ukraine netted ~100 km² back and has retaken 600+ km² since the start of 2026 (its biggest gains since the August 2024 Kursk incursion). Syrskyi reports Ukraine has, for the first time, surpassed Russia in daily offensive operations; combat engagements that ran 30–70 in Russia's favour in March now split ~50–50. The fight concentrates on three southern sectors where Russia has massed 140,000+ troops (71,000 in Oleksandrivka) plus the Pokrovsk and Kostiantynivka axes in Donbas — but Russia is stalled at Kostiantynivka after six months and abandoned its Stepnohirsk push after a French assessment of ~250 casualties per km² gained. Both Kyiv and Berlin now read a slowing front as a narrow window for talks before winter.

- 1 8 Jun 2026 Syrskyi: Ukraine retook 600+ km² in 2026, ~100 km² net in MayPokrovsk / Oleksandrivka / Huliaipole
On 8 June 2026 Syrskyi said Ukraine had retaken more than 600 square kilometres from Russian control since the start of 2026 and kept the initiative in some areas, reporting that in May alone Ukraine recaptured nearly 100 km² more than it lost. He identified Pokrovsk, Oleksandrivka and Huliaipole as the most intense sectors. The figure followed Zelensky's late-May claim of 590 km² liberated, and a Ministry of Defence tally of 88,000+ targets struck and ~30,500 Russian personnel neutralised across the front in May; independent verification remains difficult.
Net territoryA reported net +100 km² in May, atop 600+ km² for 2026, inverts the attacker–defender balance of the whole positional phase: for the first time since 2023 the line is moving in Ukraine's favour on a monthly basis, not just locally.Sector focusNaming Pokrovsk, Oleksandrivka and Huliaipole as the hottest sectors aligns Ukraine's counterattack effort with exactly where Russia massed its 140,000 troops — both armies are contesting the same southern land-bridge and Donbas-gateway ground.Verification caveatBoth Syrskyi's 600 km² and Zelensky's 590 km² are Ukrainian claims that independent monitors can't fully confirm, so the magnitude is a political signal aimed at the pre-winter talks window as much as a verified battlefield fact. - 2 8 Jun 2026 Russia claims capture of Molocharka near Kostiantynivka as Ukraine reports 240 clashesMolocharka, near Kostiantynivka
Russia's Defence Ministry claimed on 8 June 2026 that its forces captured the village of Molocharka (Khimik), about 3 km north of Kostiantynivka in Donetsk. Ukraine's General Staff reported 17 attacks near six settlements on the Kostiantynivka front but did not mention Molocharka, and Ukrainian authorities did not comment. The same day the General Staff logged 240 combat engagements front-wide, with the heaviest fighting in the Pokrovsk sector (30 assaults repelled) and Huliaipole (38 attacks); Russia flew 86 airstrikes dropping 265 guided bombs and deployed 9,184 drones, and total Russian losses since February 2022 reached approximately 1,374,950 personnel.
Incremental gainA claimed 3-km advance to a single village north of Kostiantynivka is the texture of the 2026 Russian offensive — village-by-village creep that Ukraine neither confirms nor denies, consistent with the 2.63 km²/day rate, not a breakthrough.Sector pattern240 daily clashes still peaking at Pokrovsk (30) and Huliaipole (38) confirms the two hottest sectors are the Donbas gateway and the southern land-bridge front, the same two contests every day's tally circles back to.Cumulative costThe 1.37 million Russian-loss figure, climbing ~2,700 a day across these tallies, is the running price of the offensive — the attrition ledger that, set against 14 km² gained in May, quantifies why the push is judged halted. - 3 6 Jun 2026 Russia masses 140,000+ troops across three southern sectors, Syrskyi reportsSouthern front (Oleksandrivka / Huliaipole / Orikhiv)
Syrskyi reported on 6 June 2026 that Russia had concentrated more than 140,000 troops across three hot southern sectors — over 71,000 in the Oleksandrivka sector, with similar numbers in the Huliaipole and Orikhiv sectors. On a frontline visit he ordered additional equipment and ammunition and met Unmanned Systems Forces commander Robert Brovdi. Spokesperson Viktor Tregubov said the highest activity was on the Lyman front, where Russia is trying to advance toward the Sloviansk–Kramatorsk agglomeration but is being stopped by prepared defences; near Kupiansk, Russia massed drone units to hit Ukrainian logistics on the east bank of the Oskil, while a push via Holubivka failed. 269 combat engagements were recorded in 24 hours.
Order of battle71,000 men in Oleksandrivka alone, with comparable masses at Huliaipole and Orikhiv, shows Russia is still loading the southern land-bridge fronts — concentrating force where it most needs to deepen the Crimea corridor, even as gains there shrink to single-digit km².Sloviansk–Kramatorsk axisThe Lyman push toward the Sloviansk–Kramatorsk agglomeration is the strategic object of the eastern offensive: those twin fortress cities anchor Ukraine's Donbas defence, so Russian effort on Lyman is the real test of whether the offensive is dead or merely paused.Logistics targetingMassing drone units to strike Ukrainian supply across the Oskil at Kupiansk shows Russia adapting to the drone-density battlefield by attacking logistics rather than storming positions — the same interdiction tactic Ukraine uses against Russian rear convoys, now aimed back. - 4 6 Jun 2026 Russia stalled at Kostiantynivka for six months as it braces for a Donbas summer pushKostiantynivka, Donetsk Oblast
Russia's advance in Donetsk Oblast remained slow on 6 June 2026, with forces stalled at Kostiantynivka for six months and 2026 territorial gains averaging only 2.63 km² per day. Ukrainian forces prepared for an expected Russian summer offensive against the Donbas strongholds of Chasiv Yar and Kostiantynivka, which guard the approach to the fortress cities of Sloviansk and Kramatorsk. British Defence Intelligence reported (4 June) that small-scale Ukrainian counterattacks and drone strikes on Russian logistics — trucks in Donetsk city and along the M-14 highway — were slowing Russian advances, even as the situation inside Kostiantynivka deteriorated with Russian units entering the city.
Gateway geographyChasiv Yar and Kostiantynivka are the western gateway to Sloviansk and Kramatorsk; six months stalled at Kostiantynivka means Russia has not opened the door to the Donbas fortress belt that has anchored Ukraine's eastern defence since 2014.Logistics interdictionBritish intelligence crediting drone strikes on trucks along the M-14 highway and in Donetsk city identifies the specific mechanism throttling the offensive: Ukraine is starving the assault of fuel and supply rather than only contesting the trench line.Urban grindRussian units entering Kostiantynivka while the daily advance averages 2.63 km² is the 'meat-grinder' pattern of Bakhmut and Avdiivka resumed — costly block-by-block urban fighting that buys metres, the template of the 2023–24 attrition phase. - 5 5 Jun 2026 273 combat clashes in a day; Pokrovsk and Huliaipole the heaviest sectorsPokrovsk / Huliaipole sectors
Ukraine's General Staff reported 273 combat clashes in the 24 hours to 08:00 on 5 June 2026, with the most intense fighting in the Pokrovsk sector (41 assaults) and Huliaipole sector (37 attacks). Russia conducted 95 airstrikes dropping 289 guided bombs and 3,470 shelling attacks; Ukrainian forces struck 14 enemy personnel clusters, two command posts and three artillery systems. Fighting also spanned the Kupiansk, Lyman, Sloviansk, Kramatorsk, Kostiantynivka, Oleksandrivka, Orikhiv and Dnipro River sectors, with daily totals through 6–8 June staying in the 223–269 range and the hottest sector alternating between Pokrovsk and Huliaipole.
Front geometryA clash list running Kupiansk–Lyman–Sloviansk–Kostiantynivka–Oleksandrivka–Orikhiv–Dnipro maps the live 1,000-km line in one tally — the war is fought simultaneously along the whole contact line, not at a single decisive point.Glide-bomb tempo289 guided aerial bombs in a day is Russia's standing substitute for ground breakthrough: when infantry assaults stall, Russia leans on stand-off glide bombs to soften Ukrainian positions, the air-ground link Sweden's pledged Gripens are meant to contest.Twin hotspotsThe heaviest sector alternating between Pokrovsk (Donbas gateway) and Huliaipole (southern land bridge) day to day confirms Russia is pressing both its strategic objectives at once and getting decisive results at neither. - 4 Jun 2026 French assessment: Russia suffers ~250 casualties per km² gained as war enters a new phaseSouthern front (French assessment)
A French military assessment reported on 4 June 2026 that Russian forces were suffering about 250 casualties for every square kilometre of territory gained, with the slow Russian progression halted by Ukrainian resistance. The assessment framed the war as entering a phase in which Ukraine aims to force negotiations rather than recapture all occupied territory. Earlier, Russia had failed to meet a command deadline to capture Ternuvate and Kosivtseve by the end of May, per Southern Defence Forces spokesperson Vladyslav Voloshyn, who reported 50+ combat engagements per day for four straight days and Russian drone strikes rising to 650–700 per day on that axis.
Cost metric250 casualties per km² gained is the single number that quantifies why Russia's offensive is unsustainable: each kilometre of the land bridge or Donbas now costs a reinforced platoon's worth of men, a price the 14-km²-per-month gain cannot justify.Strategic objective shiftThe French read that Ukraine now fights to 'force negotiations rather than recapture all occupied territory' reframes the ground war's purpose — territory as leverage for a settlement, matching Zelensky's pre-winter window rather than a march to the 1991 borders.Missed deadlinesRussia failing to take Ternuvate and Kosivtseve by its own end-of-May deadline — like the Stepnohirsk and Verkhnia Tersa misses — shows Kremlin timetables repeatedly outrunning what the front can deliver, the gap ISW ties to inflated command maps. - 4 Jun 2026 Russia claims Huliaipilske as it rotates fresh brigades onto the Huliaipole axisHuliaipilske, near Huliaipole
Russia's Defence Ministry claimed on 4 June 2026 that its forces captured Huliaipilske, about 16 km west of Huliaipole, after earlier failing to take Verkhnia Tersa and Vozdvyzhivka and deploying reinforcements to the 5th Army; Ukraine's General Staff reported 37 Russian assaults near 12 settlements on the Huliaipole front but did not confirm the loss. On 1 June, Southern Defence Forces spokesperson Voloshyn reported Russia rapidly rotating its offensive grouping on the Huliaipole axis — deploying the 57th and 60th Separate Motor Rifle Brigades and the 55th Naval Infantry Division for June operations aimed at penetrating deeper into Ukrainian defences.
Unit rotationNaming the 57th and 60th Motor Rifle Brigades and the 55th Naval Infantry Division shows Russia feeding fresh formations onto the Huliaipole axis — the order-of-battle signature of an army trying to restart a stalled push by swapping spent units, not by maneuver.Land-bridge aimPressing west of Huliaipole is an attempt to widen the buffer over the Crimea land bridge and threaten Zaporizhzhia's defences from the southeast; gaining a village 16 km out, after failing at Verkhnia Tersa and Vozdvyzhivka, is marginal progress toward that goal.Claim disciplineRussia announcing Huliaipilske while Ukraine logs 37 assaults but stays silent on the village fits the 2026 pattern of contested capture claims — Moscow's maps running ahead of confirmed control, the same inflation ISW says misleads Putin. - 2 Jun 2026 pivotal ISW: Ukraine has 'largely halted' Russia's 2026 spring–summer offensiveFront-wide (ISW assessment)
The Institute for the Study of War assessed on 2 June 2026 that Ukrainian forces have largely halted the Russian Spring–Summer 2026 offensive, with Russian territorial gains in May a fraction of those in May 2025. ISW attributed the slowdown to battlefield shifts rather than weather, noting Ukrainian advances near Pokrovsk and in the Kostyantynivka direction even as Russia gained near Slovyansk. It separately judged that Putin likely holds a false perception of Russian success because the high command feeds him exaggerated maps, leaving him resisting pressure to cut defence spending in the belief Russia can win in the near term.
Battlefield assessmentAn independent halting of a named seasonal offensive — gains 'a fraction' of May 2025 — is the central fact of the 2026 ground war, and ISW pins it to Ukrainian fires and drones rather than to mud or heat, removing the seasonal excuse Russia usually cites.Command informationISW's specific claim that inflated staff maps mislead Putin links the battlefield stall to a decision-making failure: if the Kremlin's own picture overstates progress, Russia keeps ordering assaults (Stepnohirsk, Kostiantynivka deadlines) that the real front cannot support.Resource signalPutin resisting defence-spending cuts while gains collapse means Russia is paying a rising 2026 price for a falling return — the attrition-curve inversion that underpins both Ukraine's and Berlin's read of a closing window. - 1 Jun 2026 pivotal Russian gains fall to 14 km² in May — lowest in three years — despite 37.5% more assaultsFront-wide (DeepState / ISW)
Ukrainian military analysts DeepState reported that in May 2026 Russian forces captured only 14 square kilometres of Ukrainian territory, the lowest monthly figure in three years, even as Russian assaults rose 37.5% to over 7,000 attacks. ISW assessed that Russia's 2026 advance has slowed sharply, with Ukraine reclaiming more ground than Russia for the first time since 2023. Analysts credited Ukraine's expanded drone operations, mounting Russian casualties, and command changes including a new defence minister; Zelensky dated the loss of Russian momentum to December 2025.
Cost-exchangeRussia spending 37.5% more assaults (7,000+) to take 14 km² is the attrition ratio turning negative — effort up, yield down — the quantified core of the 'offensive halted' claim and a direct measure of diminishing returns on Russian mass.Initiative shiftISW's finding that Ukraine reclaimed more ground than Russia 'for the first time since 2023' marks a reversal of the positional-warfare baseline that had favoured the attacker since the failed 2023 counteroffensive.AttributionCrediting expanded drone operations plus a new defence minister and commanders ties the slowdown to specific, durable inputs — drone density and command reform — not a one-off, suggesting the trend can persist rather than reverse with the weather. - 1 Jun 2026 Ukraine reverses its manpower crisis as Russian combat performance wanesFront-wide (force-structure analysis)
An analysis published 1 June 2026 reported that Ukraine has reversed its manpower crisis through military reforms — forming army corps, extending training and improving combined-arms integration of infantry, drones, artillery and armour — achieving a net positive inflow of troops and favourable casualty ratios. Russian forces, meanwhile, suffer declining combat performance from poorly trained recruits, corruption and logistical failures, with battlefield maps diverging from reality. Concurrent reports detailed unmanned ground vehicles taking over front-line logistics: Ukraine's 42nd Brigade used a Liut UGV with a Belgian FN MAG to suppress a Russian assault on the Novopavlivka axis, and the 115th Brigade cleared Novoplatonivka with a robotic system.
Manpower turnA net positive troop inflow — reversing the recruitment shortfall that defined Ukraine's 2024–25 — is the structural change behind the tempo shift: counterattacks require fresh infantry, and the corps reforms are what supply it.Robotics on the lineUGVs like the Liut running logistics and suppressing assaults where drone density makes manned supply 'suicidal' is the concrete adaptation reshaping the ground war — machines absorbing the casualties that the 12-minute Stepnohirsk math otherwise imposes on men.Asymmetric degradationUkraine improving combined-arms integration while Russia leans on poorly trained recruits and corrupt logistics widens a qualitative gap that compounds the territorial reversal — the same divergence ISW reads in Russia's inflated command maps. - 1 Jun 2026 Kyiv and Berlin read a slowing front as a narrow window for talks before winterKyiv (policy)
President Zelensky said on 1 June 2026 that Russia had been losing battlefield initiative since late 2025, creating a limited window for diplomacy before winter, with Presidential Office figures saying Ukraine had been instructed to seek an end to the active phase of the war before winter. German officials concluded that Russia's military setbacks and sanctions pressure were opening a 'window for talks,' envisioning a ceasefire along the current contact line with security guarantees for Ukraine, and prepared an E3-led (Germany, UK, France) negotiation format. On 8 June Zelensky said he was open to freezing the front lines as the quickest path to a ceasefire.
Battlefield-to-table linkBoth Kyiv and Berlin explicitly tie the diplomatic opening to the slowing front — a halted Russian offensive is the precondition that makes a 'window before winter' credible, the clearest case of ground results driving the negotiating clock.Freeze-line proposalZelensky's openness to freezing the current contact line concedes that the 600+ km² retaken in 2026 is leverage for a settlement, not a prelude to retaking all occupied land — the same 'force negotiations' logic the French assessment described.Contact-line stakesA ceasefire 'along the current contact line' would freeze the roughly 1,000-km front roughly where it sits — making every village contested at Kostiantynivka, Huliaipole and Stepnohirsk a potential permanent border, which is why both armies still push for marginal gains. - 25 May 2026 Ukraine's 118th Brigade holds Mala Tokmachka for 1,500+ days under constant assaultMala Tokmachka, Zaporizhzhia Oblast
Ukraine's 118th Separate Mechanised Brigade has held the village of Mala Tokmachka in Zaporizhzhia Oblast for over 1,500 days under continuous Russian artillery, aviation and drone attack, earning a Book of Records of Ukraine certification on 25 May 2026 and outlasting historic sieges such as the Roman siege of Carthage (~1,100 days). The village, once home to 3,000 people, now lies in ruins with about 100 residents. Russia has repeatedly claimed its capture but never taken it; the position protects the city of Orikhiv and blocks Russian forces from opening assault corridors deeper into the oblast.
Defensive anchorMala Tokmachka shielding Orikhiv and denying Russia an assault corridor deeper into Zaporizhzhia is the concrete payoff of the 1,500-day hold — one ruined village pinning an entire axis of the southern land-bridge front.Endurance as attritionA position held since the war's first months, surviving repeated false capture claims, embodies the positional-warfare logic of 2023–25: defence that refuses to break converts every Russian assault into casualties without yielding ground.Information contestRussia repeatedly claiming Mala Tokmachka's capture while the 118th still holds it is a microcosm of the wider map-inflation problem — the same gap between declared and actual control that distorts the Kremlin's view of the front. - 21 May 2026 Ukraine liberates 400+ km² since winter; biggest gains since the 2024 Kursk incursionOleksandrivka / Kupiansk / Zaporizhzhia
Ukrainian counterattacks have liberated over 400 square kilometres in southern Ukraine since winter, recaptured much of Kupiansk and taken settlements in Zaporizhzhia Oblast, with Syrskyi reporting Ukrainian offensive actions now exceed Russia's. Drone strikes hit 19,203 Russian personnel in the first 19 days of May alone, outpacing Moscow's recruitment. The gains — the largest since the August 2024 Kursk incursion — included a new offensive on the Oleksandrivka front, liberating at least 46 km² near Novoselivka in Donetsk and clearing Voronne, Sichneve, Piddubne, Tovste, Novokhatske and Zelenyi Hai. Third Army Corps commander Andriy Biletsky called the next six-to-nine months a turning point.
Scale benchmark400+ km² since winter being framed as the largest gain since the Kursk incursion of August 2024 sets a concrete yardstick — Ukraine's first sustained territorial recovery in nearly two years, not isolated village swaps.Recruitment raceStriking 19,203 Russians in 19 days and 'outpacing Moscow's recruitment rate' is the mechanism behind the slowdown: drone attrition is removing men faster than Russia can replace them, the lever that converts a held line into a moving one.Timing pressureBiletsky calling the next 6–9 months a turning point and urging Ukraine to improve its position 'before negotiations' shows the counterattacks are explicitly aimed at bargaining leverage, not just ground — the battlefield serving the diplomatic clock. - 20 May 2026 pivotal Syrskyi: Ukraine surpasses Russia in daily assaults for the first timePokrovsk axis
In an interview reported on 20 May 2026, Commander-in-Chief Oleksandr Syrskyi said Ukrainian forces had for the first time surpassed Russia in the number of daily offensive operations, while Russian combat intensity declined. He put Russian concentration in the Pokrovsk direction at about 99,000 personnel and warned of a possible Russian operation from Belarus to the north. Military analyst Oleksii Hetman said combat engagements were now split roughly 50–50 between Ukrainian counterattacks and Russian assaults, against 30–70 in Russia's favour in March, and likened a continued trend to the Kherson and Kharkiv reversals.
Tempo reversalDaily Ukrainian assaults exceeding Russian ones — with the engagement split moving from 30–70 to 50–50 in two months — is a measurable handover of tactical initiative, the operational underpinning of the 'halted offensive' headline.Force concentrationSyrskyi's ~99,000 figure for the Pokrovsk axis names where Russia is still trying to push, framing the eastern Donbas (not the south) as the sector where Russian mass remains heaviest even as overall tempo fades.Northern threatFlagging a possible operation from Belarus reintroduces the 2022 Kyiv-axis threat as a live planning factor, forcing Ukraine to hold reserves in the north rather than commit everything to counterattacks in the south and east. - 19 May 2026 pivotal Ukraine's Artan unit recaptures Stepnohirsk, a key defensive village near ZaporizhzhiaStepnohirsk, Zaporizhzhia Oblast
Ukrainian forces retook Stepnohirsk in Zaporizhzhia Oblast, dislodging Russian troops who had claimed control since early 2025, military intelligence (HUR) announced on 19 May 2026, crediting the special unit Artan after house-to-house clearing, aerial reconnaissance and precision fire. The village's strategic heights allow shelling of Zaporizhzhia's southern outskirts and control of logistics routes; HUR warned Russia might try to regain it. The recapture followed Russia's 13 May abandonment of its push there after heavy losses — commander Ihor Burdeinyi said a newly mobilised Russian soldier survived about 12 minutes on average — though by 29 May Russian command had tasked the 7th Air Assault Division with retaking Stepnohirsk by the end of June.
Terrain valueStepnohirsk's heights command fire over Zaporizhzhia's southern approaches and the local logistics routes, so retaking it pushes Russian guns back from the regional capital — a concrete defensive gain, not a symbolic flag-plant.Attrition shockThe '12-minute average survival' figure for newly mobilised Russians at Stepnohirsk is the visceral statistic of the drone-saturated southern front, and it directly explains why Russia abandoned the push on 13 May before Ukraine retook the village.Contested tempoRussia ordering the 7th Air Assault Division to recapture Stepnohirsk 'by end of June' just ten days after losing it shows the southern line is a see-saw of deadline-driven assaults — Kremlin timetables colliding with a defence that has reversed the casualty math.
Background
Russia launched a full-scale invasion on 24 February 2022, attacking toward Kyiv, across the eastern Donbas, and north out of annexed Crimea. After the drive on Kyiv failed in spring 2022, the war settled into a roughly 1,000-km line of contact running from Kharkiv Oblast in the northeast, down through the Donbas, to the Zaporizhzhia and Kherson fronts in the south. Russia occupies about 20% of Ukraine, down from a ~27% peak in March 2022; the line has barely moved since. (Al Jazeera, Wikipedia)
From 2023 the war became a grinding war of attrition centred on the mineral-rich Donbas. Russia took Soledar and Bakhmut (May 2023) and Avdiivka (February 2024) in 'meat-grinder' urban battles — Avdiivka reportedly cost more Russian lives than the entire Soviet war in Afghanistan — for tiny gains at sky-high cost. After Ukraine's 2023 counteroffensive failed, daily advances measured in metres to a few km²; by Ukraine's count Russia gained under 1% of Ukrainian territory across 2025. (Al Jazeera, ECFR)
In 2022 Russia seized a contiguous 'land bridge' through occupied Donetsk, Zaporizhzhia and Kherson oblasts, linking Crimea (which it had relied on the Kerch Bridge to reach) to mainland Russia. The southern fronts — Huliaipole, Orikhiv, Stepnohirsk, the Dnipro islands near Kherson — are the war's contest over that corridor: holding villages like Mala Tokmachka and Stepnohirsk blocks Russian assault routes deeper into Zaporizhzhia, while the R-280 highway through Melitopol is the corridor's logistical spine. (CEPA, Hudson Institute)
Colonel General Oleksandr Syrskyi (b. 1965) became Commander-in-Chief on 8 February 2024, replacing Valerii Zaluzhnyi. Soviet-trained but Ukrainian since 1991, he ran the September 2022 Kharkiv counteroffensive and the defence of Bakhmut. His 2026 doctrine is to halt Russian advances and convert defence into counterattack — backed by army-corps reforms, longer training, and a drone-density battlefield where unmanned ground vehicles run logistics and FPV swarms shred massed infantry.
