In August, Russian gains ticked upward in key sectors along the 1,200-km front line of Russia's 55-month wider war on Ukraine.

The coming winter could slow Russian advances as the trees lose their leaves and infantry infiltrators have nothing to conceal them from overhead drones. But for the next month or two, the trees will still have their leaves, and the infiltrators will still have their cover.

And that means, as fall wears into winter, Ukraine may lose yet more ground in the north and especially in Donbas region in the east, where Russia enjoys a substantial manpower and firepower advantage. "Russian forces still hold the operational initiative and are slowly capturing ... Donetsk Oblast as well as border zones in Sumy and Kharkiv Oblasts," mapper Thorkill warned.

The Russian gains belie a greater truth, however. In the middle of the fifth year of wider war, the situation on the ground only changes along the margins even as thousands die.

According to Thorkill's tally, the Russians occupied just under 220 square km of Ukrainian soil in August. That's 25% more territory than they captured in July. "The situation has deteriorated sharply in the Donbas in August," mapper Clément Molin explained.

Un été difficile en Ukraine , en cause, des décisions politiques contestables.

Après un printemps bien géré par Kyiv (aide financière de l'UE, bonne situation au front, frappes réussies à l'arrière), l'été a vu un nombre de mauvaises nouvelles pour l'Ukraine.

To be fair, the Russians are advancing much more slowly than they did a year ago. "Compared to August 2025, Russian gains are down by nearly half," Molin noted. That's cold comfort to Ukrainian civilians and defenders in the areas where the Russians are still gaining ground, however. And the sheer proximity of the most aggressive Russian formations to the most vulnerable Ukrainian settlements means it might not take much more effort on the part of the Russians to turn these settlements into battlegrounds.

The Russians' main effort is still directed at the last big free cities in Donetsk. Inching forward at great cost from several directions, Russian forces are slowly closing a pincer around Kramatorsk and Sloviansk and the tens of thousands of civilians who still live in the adjacent cities.

Thorkill's map places the forwardmost Russian forces in Mykolaivka, just 4 km east of Sloviansk. This is the middle joint of the Russian pincer. The pincer's southern claw is a zone of disputed control stretching along the road between the ruins of the city of Kostiantynivka and the battleground town of Oleksiievo-Druzhkivka.

If the Russians can march through Oleksiievo-Druzhkivka, they can lay siege to the town of Druzhkivka, a few kilometers to the northwest. If they can capture Druzhkivka, they can turn north and assault Kramatorsk, a mere 6 km away.

Ukrainian counterattacks

The most fragile part of the claw is to the north. Bucking the overall trend of Russian gains in August, Ukrainian forces counterattacked in several sectors the same month. Most dramatically, a clutch of Ukrainian mechanized and air assault brigades extended a slow advance through the town of Nove, mostly cutting across a 100-square-km salient of Russian forces around 25 km northeast of Sloviansk.

The Nove counterattacks offer some hope that targeted Ukrainian action may slow the Russian march on Sloviansk and Kramatorsk from the north. Meanwhile, a reshuffling of Ukrainian units south of Kramatorsk could improve Ukrainian defenses against an assault on the twin cities from the south.

As new Ukrainian commander-in-chief Gen. Mykhailo Drapatyi gradually addresses some of the imbalances in the Ukrainian ground forces, certain key units are getting help. Most notably, the 425th Assault Regiment is now subordinate to the 1st Azov Corps, which is responsible for the defense of Kramatorsk.

Keenly aware that the Russians intend to slowly infiltrate front-line settlements with small teams of infantry rather than rushing them with masses of easily-droned armored vehicles, the 1st Azov Corps has assigned the aggressive 425th Assault Regiment "to clear enemy infiltrators from the brigades’ areas of defense," the corps stated.

Infiltrators aren't the only problem, however. The Russians' favorite tactic combines small teams of infantry with massive aerial firepower in the form of precision-guided KAB glide bombs flung by supersonic Sukhoi Su-34 fighter bombers.

"Glide bombs hurt," Ukraine's 4th National Guard Brigade reported. "It's about 200 kg of explosives flying your way. And you can't really shoot them down like you can shoot down drones. They can collapse fortified buildings, bunkers, and entire urban blocks much more effectively than artillery."

After the dust settles from the glide bomb impacts, Russian infantry "infiltrate through the damaged areas, using the ruins for cover and concealment," the national guard brigade explained.

The same lack of long-range air defenses that exposes Ukrainian cities to relentless Russian bombardment also deprives front-line forces of protection from the Su-34s and their glide bombs. And so the Russians can keep bombing and keep infiltrating as long as the trees offer some concealment for the infantry.

The clock is ticking. The Russians will aim to position their forces for more direct assaults on Kramatorsk and Sloviansk no later than next year. The Ukrainians will aim to slow down the Russians, trading a little space for more time. Time Drapatyi may use to institute further reforms in the Ukrainian ground forces.

Zooming out and taking the long view, no one should expect major changes on the map of Russia's wider war as the fifth year of fighting grinds toward the sixth. Yes, the last two big free cities in the Donbas are in trouble. But "the overall situation remains unchanged since October 2023," Thorkill wrote.

The Russians slowly advance. The Ukrainians slowly fall back. And losses deepen on both sides.

Desperately short of missiles for its roughly 10 Patriot air defense batteries, Ukraine has just a few options as colder weather looms—and the Russians prepare to fire even more hard-to-intercept Iskander ballistic missiles at Ukrainian cities and power plants.

The Iskander is a unique threat, and Ukraine is uniquely vulnerable. The Patriot is one of just a few systems that stands any chance of hitting an incoming Iskander as the Russian missile barrels in at six or seven times the speed of sound. And the Patriot is, or was, the most plentiful anti-ballistic interceptor. It usually takes two or three of them to bring down one Iskander.

Then came Iran. Coalition forces fired an average of 225 interceptors a day during the first four days of the war against Lockheed Martin's production rate of 1.7 a day, the Foreign Policy Research Institute calculated—a 132-to-one gap between use and manufacture. Lockheed built 620 Patriots in all of 2025. And every Patriot the Americans fire at an Iranian missile is a Patriot Ukraine won't be able to fire at a Russian missile.

Ukrainian batteries have so few missiles that air defenders can do little more than watch as the 3.8-ton Iskanders and other heavy Russian missiles barrel in. "This is a really heartbreaking sight when you have equipment but you're not able to intercept any missile," Dmytro, the chief engineer of Ukraine's Patriot fleet, told CNN. "Ballistic missiles are flying over your head and you are not able to do anything with it, and behind you, there are civilians." He first ran out of interceptors in December 2025.

Across the 39-day campaign, CSIS estimates 1,060 to 1,430 Patriots were expended—more than half the US prewar inventory. At Lockheed's rate, replacing them takes three years.

And a Patriot cannot be conjured. A single PAC-3 MSE takes about 24 months to build, its solid rocket motor 30. In January the Pentagon signed a seven-year deal for Lockheed to reach 2,000 Patriots a year—by 2030, by which point the Russo-Ukrainian war will be eight years old. Far too late to save Ukraine from the coming hard winter.

The Ukrainian air force has two other batteries that can intercept ballistic missiles, both French-Italian SAMP/Ts, and they are short of missiles too. France agreed in November to send eight next-generation SAMP/Ts over two years—a schedule, not a stockpile.

Winter looms

The interceptor crisis will only worsen as winter looms and the supply of electricity for residential heating once again becomes a matter of life and death for millions of Ukrainians. Iskanders "could hit all significant non-nuclear electricity generation," Jakub Janovsky, a Czech military analyst, explained to Euromaidan Press. The Kremlin has cut production of several other missile types—including, as Euromaidan Press reported this month, the Kinzhal—to pour more into the Iskander.

"I wanted to secure 300 missiles for the Patriot systems as part of the winter package. The request from our Air Force is for 360," Ukrainian President Volodymyr Zelenskyy told journalists on 23 August, in remarks posted to X. "But when only 600 are produced a year, 360 is not easy to obtain." He has asked Washington for 5% or 10% of the US stockpile, and says Ukraine will pay. By his own account it holds about 1%.

Russia could have up to 1,300 ballistic missiles a year. Right now, they have 600–630. We have an approximate understanding of the volume they are counting on from today and through the end of winter. Roughly speaking, they could have 100 ballistic missiles a month. But they are…

— Volodymyr Zelenskyy / Володимир Зеленський (@ZelenskyyUa) August 23, 2026

What are Ukraine's non-Patriot options?

Its own ballistic interceptor

Frantic for air defenses, Ukraine is developing its own. In May, Kyiv munitions-maker Fire Point unveiled Freya, a pan-European anti-ballistic project built around the FP-7.x—a 7.25-m composite interceptor derived from the company's FP-7 surface-to-surface missile. Cued by European radars and guided in the final moments by an infrared seeker from Germany's Diehl Defence, it is meant to cost around $700,000 a shot against a Patriot's $3.8 million.

Fire Point had run at least five tests by the end of July, and co-founder Denys Shtilerman told the Financial Times mass production could begin as early as this month. But the first attempt at intercepting an actual ballistic target is planned for around July 2027—a winter away, and then some. Infrared guidance is also reckoned less reliable than radar, since spoofing can mislead the seeker.

Sanctions on the Iskander supply chain

Sanctions may seem attractive, and there is a narrow chokepoint. Ammonium perchlorate makes up 45% to 52% of the Iskander's solid fuel, and Russia has exactly one plant that makes it—the state-owned ANOSIT—according to the Economic Security Council of Ukraine.

That plant depends on imported sodium chlorate, a chemical Russia lost the ability to make when the USSR collapsed. Russia bought more than $40 million of it in 2024 and the first half of 2025, 61% from China and most of the rest from the Farg'onaazot chemical plant in Uzbekistan. The largest Russian importer, Pioneer Trade, sells on to firms that supply the Iskander's designer, its cluster-warhead maker, and the Votkinsk plant that builds the missile.

But Russia gets around sanctions by buying through third parties. And while the European Union already restricts the export of sodium chlorate to Russia, neither Farg'onaazot nor any of the Russian importers moving it is under blocking sanctions. Even where the bans hold, they just "make things more costly and less convenient," Janovsky told Euromaidan Press. "They can't stop things from happening if the other side really wants to do something."

Deep strikes against the Iskander supply chain

Ukraine has already tried this one. The main Iskander factory is in Votkinsk, 1,400 km from the border, and on the night of 20–21 February Ukrainian Flamingo cruise missiles hit it. Zelenskyy said every missile launched reached the plant. Satellite imagery confirmed damage to a workshop where Iskanders and Oreshniks are assembled; local officials reported two shops damaged and 11 people injured.

Iskander production rose anyway. So the question is not whether Ukraine can reach Votkinsk—it can, and did—but whether it can launch enough munitions at once to inflict damage that lasts. "Ukraine can try a massive saturation strike with hundreds of drones and dozens of cruise missiles to overwhelm local defenses and wreck enough of the factory complex to at least temporarily disable the production," Janovsky said. That might take essentially the entire Ukrainian deep strike force—and if it failed, Russian industry would get a months-long reprieve.

Kill the launchers before they shoot

This is the hardest one. Russian crews keep their Iskander launchers 140 to 150 km behind the front line, beyond the reach of Ukraine's HIMARS, and move them to firing positions along forest roads—sometimes for five hours—to stay out of satellite view. Once in position, a launcher needs about 16 minutes to send its first missile and four for the second, then it leaves. Twenty minutes, in the open, somewhere in a forest, a hundred and fifty kilometers away.

Ukraine is trying anyway. On 23 August, Zelenskyy said Ukrainian forces had struck an Iskander launcher near the border, and described a dedicated program to hunt the launch sites. Euromaidan Press could not independently verify the strike. He was explicit about why the program exists. "When our anti-ballistic missile stocks are at a minimum, there is another tactic," he said. "It is more difficult, and we developed it."

All options but one arrive after the cold

Option	When it delivers
Patriots from allies	Ukraine's air force asked for 360; Zelenskyy sought 300 for the winter package. Output is 600 a year, and CSIS says about half of it goes to allies and partners
Lockheed's expansion to 2,000 a year	That rate is not reached until 2030
Freya / FP-7.x interceptors	First attempt at intercepting a ballistic target planned for around July 2027
Sanctions on the supply chain	The chemical is restricted; none of the companies moving it is designated
Deep strike on the Votkinsk factory	Tried in February. Workshops hit, production still rose
Hunting the launchers	Now—one strike claimed on 23 August, not independently verified

Unable to shoot down all the Iskanders, Ukraine may have no choice but try everything all at once: sanction the suppliers, attack the supply chain, hunt the launchers, and scurry to deploy homemade interceptors. All while continuing to beg for every available Patriot.

Ukraine secret eastern counteroffensive seems to have been even more successful than some observers reported. It's possible that, in the sector just north of the town of Lyman in eastern Ukraine's Donetsk Oblast, the Ukrainian 3rd Army Corps is just a few kilometers short of encircling two Russian regiments.

That doesn't mean the Russian units can't escape. After all, there isn't a contiguous line of Ukrainian forces—nor a contiguous line of Russian forces for that matter—anywhere along the 1,200-km disputed gray zone that threads across eastern and southern Ukraine.

But the closing pincer around elements of the Russian 2nd and 144th Motor Rifle Divisions could strain the Russians' logistics and compel the Russians to reconsolidate in order to preserve their combat power—by retreating east. That would take a lot of pressure off Lyman and, by extension, also take a lot of pressure off Sloviansk and Kramatorsk, the last two big free cities in Donetsk.

Lyman, which lies 15 km northeast of Sloviansk—the northernmost of the free cities—is the main obstacle between at least six Russian regiments and Sloviansk. The Russians have been inching toward Sloviansk and Kramatorsk from several directions for months now, racing against the coming winter to position forces for a possible siege of the twin cities next year. Winter in Ukraine punishes any attacker by depriving them of the leafy tree canopy that can conceal infiltrating troops during warmer months.

According to the most recent map from analyst and mapper Thorkill, one of the more reliable observers of unit-level action in Ukraine, the Ukrainian 3rd Assault Brigade is just a few kilometers away from linking up with the 60th Mechanized Brigade in or around the village of Kolodyazi.

Galloping advance

If true, that means the 3rd Assault Brigade and adjacent units from the 3rd Army Corps have carried out one of the more successful Ukrainian counteroffensives in memory. In April they first exploited gaps in Russian defenses north of the village of Nove. In May and June they advanced toward the village. In July they captured it.

After that, the attacking Ukrainians kept pushing south into the right flank of a 10-km-by-10-km salient that advancing Russian regiments created as they maneuvered around Lyman from the north, aiming to surround the town instead of directly assaulting it on their way toward Sloviansk.

Leaving their flank exposed, the Russians trying to encircle Lyman found themselves at risk of encirclement, instead. If the 3rd Assault Brigade or 60th Mechanized Brigade—together possessing thousands of troops, on paper—can march through Kolodyazi, they will have closed a ring of loose Ukrainian control around at least two Russian regiments, also with potentially thousands of troops.

Emphasis on loose control. Again, there aren't enough Ukrainian forces on the ground north of Lyman to prevent any "encircled" Russians from retreating back to the east. But that retreat would represent a major victory for the Ukrainian defenders north and east of Sloviansk. "The fall of this salient [north of Lyman] would significantly delay the fall of Lyman," analyst and mapper AMK Mapping predicted.

Situational update on the Lyman direction:

The Ukrainian counterattacks north of Lyman are now entering their fourth month, as they come closer and closer to cutting off the Russian salient. Two pincers have been formed, which are both dangerously close to cutting the Russians… pic.twitter.com/mu2kZ4S3Jv

No one expects the Russians to halt their offensive toward Sloviansk and Kramatorsk. But in potentially taking two steps forward and one step back in their northerly march on the free cities, the Russians sacrifice time. Time the Ukrainians can use to stiffen their defenses in Sloviansk and Kramatorsk and evacuate more of the tens of thousands of civilians who remain in the cities despite the constant danger from Russian drones and bombs.

The possible extent of the Ukrainian gains north of Lyman—a 10-km march since April—is impressive given Russia's overall advantage in manpower and firepower in the east. Equally impressive is the operational security, or OPSEC, that cloaked the offensive until now. Sure, there were a few videos of action around Nove that hinted at a major Ukrainian action.

But the units involved exercised surprising discipline, and prevented too much information from leaking. "Someone in the 3rd Corps responsible for [OPSEC] is actually trying to do their job diligently and has quite effectively cut off information," Thorkill noted. The secrecy may have facilitated the Ukrainian advance by delaying any sense of panic among the Russian commanders who are responsible for reinforcing the Lyman salient, but who also tend to ignore bad news as long as possible because they know it could reflect poorly on them.

News of the counteroffensive is now available for all to see, even if official Ukrainian sources have yet to confirm it. That may mean time is running out for the 3rd Army Corps to close its pincer before the Russians retreat or reinforce. AMK Mapping has already seen some evidence of a "partial withdrawal from the most vulnerable positions in the salient.

Russian forces are fighting against time to close a pincer around the last free cities in eastern Ukraine. The deadline: the coming winter, which will strip the leaves from the trees and leave any attacking force exposed to overhead surveillance and attack.

But in one key sector, Ukrainian forces are spoiling the coordinated Russian operation to partially surround Sloviansk and neighboring Kramatorsk. With admirable operational security, or OPSEC, a clutch of Ukrainian brigades under the 3rd Army Corps hasn't just blunted the advance of the Russian Center Group of Forces—it has pushed the Russians back.

This Ukrainian counterattack along the axis through the town of Lyman, ongoing since May, has largely escaped widespread notice. Yes, there is some scant video evidence of Ukrainian attacks. And yes, a few analysts have adjusted their maps to account for apparent Ukrainian advances, especially in the direction of Nove, a Russian-occupied village 15 km north of Lyman, which itself lies 15 km north of Sloviansk.

Ukrainian forces have been conducting for weeks two unnoticed counter-attacks in two directions of the frontline.

With barely any geolocation, the Ukrainians kept a good level of OPSEC and the russians have been reluctant to publish videos from these areas.

But for the most part, Ukrainian and Russian sources have avoided talking about Lyman. "The Ukrainians kept a good level of OPSEC and the Russians have been reluctant to publish videos from these areas" depicting their retreats, analyst and mapper Clément Molin noted in June, just a few weeks after the Ukrainians attacked toward Nove.

Molin, for one, expects the OPSEC to lift in the coming days. "By the end of the month, we should have an official update on the good results of a Ukrainian offensive that has largely remained secret," he wrote on Monday.

April offensive

The Ukrainians' limited counteroffensive around Lyman apparently kicked off on in mid-April. One of the first attacks that left any real evidence occurred on 22 May, when a small Ukrainian mechanized force—perhaps from the 60th or 66th Mechanized Brigade, the 77th Air Assault Brigade, or the Presidential Brigade—attacked in armored trucks and M-113, Stryker, and BTR-4 armored personnel carriers. Heavy bomber drones flew top cover.

The Russian 144th Motor Rifle Division fought back with its own drones. Interceptor drones took aim at the bombers. First-person-view and heavy bomber drones blasted at least one BTR-4, hitting it before and after it dropped off its infantry passengers. Drones struck some of the disembarked Ukrainian infantry.

How many Ukrainian troops survived and entrenched in new positions on 22 May is unclear. Regardless, the Ukrainian 3rd Army Corps wasn't done with Nove. Attacks continued. And sometime after the 22 May assault on Nove, "the Ukrainians managed to consolidate their gains," Molin concluded after scrutinizing a few videos and some satellite imagery.

By early July, Ukrainian forces had succeeded in "operationally encircl[ing] the Russian forces defending the village of Nove," according to analyst and mapper Thorkill. "Fierce fighting is currently underway to expel the Russians from that locality," Thorkill reported at the time.

The aim of the Ukrainian counterattacks is obvious. The 3rd Army Corps intends to put pressure on the northern right flank of 10 km-by-10-km salient jutting into the battleground north of Lyman. The Russian 144th Motor Rifle Division has been pouring troops into the salient, clearly intending to surround and isolate Lyman instead of directly assaulting it—all in order to clear a path toward Sloviansk.

Salients are risky for both sides, however. The farther the Russians extend their Lyman salient, the more exposed they are on their flanks. The Ukrainians know this. And even if the 3rd Army Corps can't fully cut across the salient in order to surround the Russians inside of it, the corps can at least take advantage of the salient's exposed flanks.

Capturing Nove, on the very northern edge of the salient, could allow the Ukrainians to bring to bear more artillery and drones on the Russians south of Nove. The 3rd Army Corps doesn't have to fully encircle the Russian troops closest to Lyman in order to hammer them with withering firepower.

Just how successful the 3rd Army Corps has been in its local counteroffensive could become clearer very soon. That won't spell lasting relief for Sloviansk and Kramatorsk, however. Fighting against the clock as summer begins turning into fall and then winter, the Russians are slowly advancing toward the twin cities from several directions.

The siege of Kramatorsk and Sloviansk is coming. Perhaps not this year, but surely by 2027. To fully safeguard the twin cities, the Ukrainians would need to duplicate their success north of Lyman along several other directions.

That's a big ask of a Ukrainian force that's overall still outnumbered and outgunned.

The Russian navy still has enough missile-armed warships in its battered Black Sea Fleet to sustain Kalibr cruise missile attacks on Ukrainian cities, if recent launches are any indication.

Overnight on 19 August, an unscathed Russian corvette lobbed eight Kalibrs at Ukraine. Seven were intercepted. The eighth struck the Antonov Aircraft Plant in Kyiv, according to the open-source monitor OSINT Warfare, in an attack that killed 15 overall. Ukrainian commanders had hoped that wouldn't be possible. A week earlier, they thought they had knocked the Kalibr shooters out of the fight.

Overnight on 12 August, Ukrainian drones and missiles targeted the Black Sea Fleet's main anchorage in Novorossiysk in southern Russia. Russians on the ground recorded fireballs billowing into the night sky, seemingly indicating significant damage to the port or its moored warships, potentially including the Black Sea Fleet's seven or eight surviving frigates, corvettes, and submarines that are compatible with the 2,500-km Kalibr.

The Ukrainian general staff in Kyiv claimed its forces had struck three Kalibr carriers—the frigates Admiral Makarov and Admiral Essen and a Buyan-M corvette—as well as a lightly armed guard ship. But the uncertainty was, and still is, high. Even the general staff stressed its munitions had inflicted "varying degrees" of damage "according to preliminary information."

"Information is being clarified," the general staff stressed.

Footage shows eight 3M14 Kalibr cruise missiles being launched from a Buyan-M-class corvette at the Novorossiysk Naval Base in Russia’s Krasnodar Krai. https://t.co/fiQ0qhUhZ0 pic.twitter.com/GShALhfh4a

— OSINTWarfare (@OSINTWarfare) August 19, 2026

When the sun rose over the following days, commercial satellites snapped high-resolution photos of Novorossiysk, helping analysts assess damage from the 12 August strikes. The photos were hard to interpret. Yes, there were dark patches on the hulls of the two frigates and single corvette, but the discoloration didn't necessarily indicate drone or missile damage—to say nothing of confirming serious damage.

The pro-Ukraine Conflict Intelligence Team concluded Admiral Makarov and Admiral Essen "sustained damage in the area of their launchers," potentially impacting the ships' ability to fire Kalibrs.

A later battle-damage assessment by OSINT account Absolutely Reliable Source said both frigates had suffered critical damage. It assessed that direct hits on Admiral Essen destroyed its eight-cell 3S14 vertical launch system for Kalibr missiles, while strikes on Admiral Makarov caused an internal detonation and burned out its 3S14 launch cells. The account said both ships had lost their strike capability and would require extensive repairs.

Uncertainty

Caution was prudent. In the first three years of Russia's wider war on Ukraine, Ukrainian forces succeeded in destroying or damaging around two dozen of the roughly 85 large ships in the Black Sea Fleet. Perhaps most notably, a pair of Ukrainian Neptune cruise missiles holed and sank the Russian missile cruiser Moskva in April 2022.

But the strikes mostly missed the Kalibr carriers. Yes, the Ukrainians took out a Kalibr-armed Improved Kilo-class submarine in September 2023 and a Karakurt-class corvette, also armed with Kalibrs, in November 2023. But that left at least seven Kalibr shooters in the Black Sea Fleet. Eight if the Russians have managed to repair the Improved Kilo that apparently suffered some damage from a Ukrainian one-way unmanned attack submarine back in December.

It wasn't for a lack of trying that Ukrainian forces failed to eliminate, or even seriously dent, the Black Sea Fleet's Kalibr capacity prior to the 12 August raid on Novorossiysk. On 22 May, Fire Point FP-1 drones operated by the Ukrainian 414th Separate Unmanned Strike Aviation System Brigade motored the roughly 430 km to Novorossiysk and spotted a warship moored to a pier.

The 414th Brigade believed it was Admiral Essen—and also believed it may have hit the ship. "The frigate Admiral Essen … entered the strike zone," the brigade crowed. "Damage level unknown."

In fact, it seems the ship the propeller-driven FP-1 barreled toward, and potentially struck with its warhead, wasn't Admiral Essen. The vessel in the FP-1's video feed, relayed via satellite or a mesh radio network, appeared to be a derelict Krivak-class frigate. Not Admiral Essen.

It was yet another near miss. Earlier, on 6 April, FP-1s dove down on Admiral Makarov. The Ukrainian Unmanned Systems Forces posted footage from the FP-1s' forward-facing thermal cameras that indicated the drones got close to Admiral Makarov. But the footage didn't point to an obvious hit.

Overhead satellite imagery from later on 6 April seemingly told a more complete story. The drones may have left a scorch mark on the frigate's bow, but there was no sign of structural damage. If the 12 August raid really did inflict meaningful damage on Admiral Makarov and Admiral Essen and a Buyan-M, it represented a profound reversal for Ukrainian forces. After trying and trying again for months, they'd finally hit some of the ships that really mattered among the survivors of the Black Sea Fleet.

The problem for the Ukrainians is that, even if three Kalibr shooters are temporarily out of the fight, there are still four, possibly five, Kalibr shooters left. And that's enough to sustain frequent attacks on Ukrainian cities. A single Buyan-M corvette can fire eight Kalibrs at a time. And eight, as it turns out, is a typical number of Kalibrs in the mix when Russian air, sea, and ground forces launch their combined drone and missile barrages.

The Black Sea Fleet reminded everyone of that uncomfortable fact overnight on 19 August. A Buyan-M corvette at Novorossiysk fired eight Kalibrs—exactly one magazine—into a barrage that also carried Onyx and Zircon missiles, Iskander-M and KN-23 ballistic missiles, three dozen air-launched cruise missiles, and 168 drones. Ukrainian air defenses stopped seven of the eight Kalibrs. They could not stop the ballistic missiles, and the eighth Kalibr got through to the Antonov plant, which had already been hit that night by Iskanders and Zircons.

If the attack on 12 August actually did eliminate or even just temporarily sideline three Kalibr carriers, it still represents a partial victory for Ukraine. It's likely no fewer than four shooters remain. And given how long it took Ukrainian deep strike forces to maybe damage Admiral Makarov and Admiral Essen and that Buyan-M, the Black Sea Fleet may be able to continue blasting away at Ukrainian cities for many months to come.

Ukraine's southeastern counteroffensive has rolled back Russian advances at the intersections of Zaporizhzhia, Dnipropetrovsk, and Donetsk Oblasts. The Ukrainian attacks set back, by months if not years, the Russian plan for marching on Zaporizhzhia City from the northeast.

But there's a shorter path for the Russians: the southern approach through the town of Orikhiv, around 50 km from Zaporizhzhia City. And the Russians may not need to travel all of it. The stated Russian objective on this axis, according to the Institute for the Study of War, is to advance within tube artillery range of Zaporizhzhia City—which means getting to within 20 or 30 km of a regional capital, not capturing it. That is what Russian forces did to Kharkiv.

The route is short but hard. And for three years, it has been blocked at its first obstacle by the ruins of a prison.

The first obstacle for the Russians is the village of Mala Tokmachka. In particular, the thickly built ruins of a former prison, which function as an interlocking series of bunkers for the Ukrainian 118th Mechanized Brigade. The second obstacle is Orikhiv itself, which sits astride all the passable roads leading to Zaporizhzhia City.

The Russian Defense Ministry announced the capture of Mala Tokmachka on 16 November 2025. Ukrainian government sources still had the village under Ukrainian control in April 2026. Russian milblogger Boris Rozhin's repeated claims that the village was nearly cleared became, in Meduza's account, the most popular Russian military meme of the first half of 2026—shorthand for the distance between what the Russian army announces and what it holds.

Observer Thorkill has watched closely as Russian forces have probed for weaknesses in Ukrainian defenses between the disputed gray zone and Zaporizhzhia City—and found very few.

The Russian army's 270th Motor Rifle Regiment, which is part of the 42nd Motor Rifle Division, has been trying to advance through Mala Tokmachka "for many months," Thorkill noted. But the Russian attacks "have always faltered against the strongly fortified strongpoint in the complex of ruins of the former prison buildings."

If the Russians can't capture Orikhiv, they can't get their artillery within range of Zaporizhzhia City. But they can't capture Orikhiv if they don't first capture Mala Tokmachka. And they can't take Mala Tokmachka if they don't overrun the old prison.

Surround first, storm later

Frustrated in their attempts to directly assault the prison, the Russians took a different approach in early July. Borrowing tactics that have worked for Russian field armies all along the 1,200-km gray zone, the Russians set out to cut off Mala Tokmachka and starve its garrison before trying again to capture the prison complex.

The geography lends itself to this approach. The Russians control the village of Robotyne, 10 km south of Orikhiv, as well as the road leading north from Robotyne through the village of Novodanylivka, which lies just south of the Mala Tokmachka-Orikhiv conglomeration.

If the conglomeration has a soft underbelly, it's Novodanylivka. And in a series of actions in early July, the 71st Motorized Rifle Regiment pushed enough small infiltration groups into Novodanylivka to take the village from the 118th Mechanized Brigade. In capturing Novodanylivka, the Russians "drove a narrow wedge into the Ukrainian defense," according to Thorkill.

The wedge was not the end of the plan. It was the preparation for it. With Novodanylivka in Russian hands and the supply route between Orikhiv and Mala Tokmachka under threat, the Russians came back to the assault.

Five days in August

In the five days to 17 August, Russian forces "massively stepped up their assault operations towards Orikhiv from several different directions, resulting in a partial collapse of Ukrainian defences," mapper AMK Mapping reported. The mapper counted a Russian gain of around 26 sq km across the sector.

The Russians re-established control over the eastern part of Mala Tokmachka and began infiltrating the northern part. Several groups crossed north over the Kinska River and are now attacking Ukrainian trench fortifications on the tactical heights beyond. "If they are able to consolidate," AMK Mapping wrote, "a defense of Mala Tokmachka by Ukraine will become nearly impossible." To the northeast, Russian forces broke through north of Bilohirya, putting the Ukrainian troops there at risk of being cut off.

The Polish Centre for Eastern Studies reached a similar reading on 18 August, reporting that Russian assault sub-units had begun to replace the sabotage and reconnaissance groups, that the battle for the eastern part of Orikhiv appeared to have begun, and that the eastern part of Mala Tokmachka was most likely under Russian control.

Heavy fighting continues for the prison complex and the residential streets around it. "The goal of the offensive operations by the Russian 42nd Motorized Rifle Division is not, for the time being, the capture of Orikhiv," Thorkill wrote, "but rather the elimination of the presence of Ukrainian soldiers in the Mala Tokmachka area."

If the Russians can squeeze the Ukrainians out of Mala Tokmachka, they could pivot toward Orikhiv without worrying about Ukrainian positions at their rear. And they would be one strongpoint closer to putting a regional capital of several hundred thousand people under daily artillery fire.

On or around 12 August, a Russian Geran-4 attack drone found a Ukrainian navy CB-90 in the waters off the Kinburn Spit and attacked it. Three days later, another Geran-4 went after a Ukrainian tugboat in the same waters. If the CB-90 sank, it may be the first one the Ukrainian navy has lost.

The CB-90 is a Swedish design and a Swedish gift, and it is the reason Ukraine can raid the spit at all. Fifteen meters long, armored against small arms, gun-armed and capable of around 40 knots, it can put 21 troops—or a ton of machinery—onto a hostile beach and be gone before the defenders react. Sweden has supplied most of the more than 38 in Ukrainian service; Norway, the Netherlands and the Ukrainian billionaire Rinat Akhmetov's Steel Front initiative supplied the rest. Swedish instructors trained the crews.

Russia has now answered Ukraine's raids, and it is aiming at the boats rather than the raiders. The Geran-4s doing the hunting are jet-propelled, AI-assisted and fast enough to outrun most of what Ukraine can shoot back with. If the campaign continues, it could close the approach that has made the raids possible.

What that approach makes possible is worth spelling out. In July, unmanned boats belonging to the Ukrainian Territorial Defense Forces landed at least one gun-armed unmanned ground vehicle on the Kinburn Spit, the westernmost Russian outpost in occupied Ukraine. As aerial drones watched, the UGV opened fire on a nearby Russian installation. No Ukrainian was anywhere near the beach.

Russian forces on the Kinburn Spit can monitor Ukrainian maritime traffic, making the narrow sandy spit a key outpost in the ongoing battle for the Black Sea's most important sea lanes. Ukrainian forces are determined to dislodge Russian forces from the spit. The Russians are determined to cling to their sandy outpost.

The Geran attacks are helping. The 12 August Geran raid targeted the CB-90. The 15 August Geran raid targeted the tugboat. It's unclear how much damage the Gerans inflicted, but it's worth noting that the CB-90 is just 15 m long; a tugboat might be slightly longer. A Geran's warhead weighs as much as 90 kg—probably enough to sink such a small vessel or burn it down to the keel.

The Ukrainian navy has only a few large warships, and they're all donated minehunters that have been waiting out the current wider war in the relative safety of European waters. The bulk of the Ukrainian fleet is made up of small patrol boats, auxiliaries such as tugs, and several types of unmanned surface vessels. These vessels defend waterways and ports and, more rarely, support offensive operations.

Spit raids

The July robot landing was one episode in a long Ukrainian raiding campaign along the spit—the kind of operation the Geran-4s are now trying to spoil.

The Geran strikes on Ukrainian boats could blunt these raids and help the Russians maintain their tenuous hold on the Kinburn Spit. The Russian strikes are part of a wider maritime campaign. Shortly after Ukrainian drone units began targeting the unregistered cargo ships and tankers belonging to Russia's shadow fleet, Russian drone and missile units retaliated—with devastating attacks on Ukrainian ports and the ships sailing to and from these ports in support of Ukraine's lucrative grain exports.

The Ukrainian attacks on the shadow fleet damaged hundreds of ships and effectively ground Russian Black Sea trade to a halt. But Russian attacks on Ukrainian ports effectively ground Ukrainian Black Sea trade to a halt, too.

The new jet-propelled Geran-4s with their AI-assisted targeting were central to the effort. Their 500 km/h top speed makes them hard to shoot down. And the AI makes jamming far less useful than it used to be: the operator locks the drone onto a target, and from there the machine vision flies the attack, holding the lock even if Ukrainian electronic warfare severs the radio link in the final seconds.

That makes the CB-90s valuable targets. Armed with guns and armored against enemy small arms fire, they're perfect for raiding far-flung enemy outposts such as those on the Kinburn Spit. But they're vulnerable to drone attack—and each one is irreplaceable in the sense that matters, since Ukraine cannot build them and has to wait for the next donation.

Ukrainian forces aren't powerless to stop the Russians from spoiling Ukrainian raids on the spit. Geran-4s might be too fast for Ukrainian gun teams, armed light aircraft, and cheap interceptor drones, but they're not too fast for supersonic Ukrainian air force MiG-29 fighters.

Several of the MiGs patrol over the western Black Sea. One crashed recently, but others remain.

The scale of Ukrainian forces' counteroffensive in southeastern Ukraine early this year is finally becoming clear. In six months of maneuver starting on 29 January, a clutch of Ukrainian units, including the 78th, 79th, 80th, 82nd, and 95th Air Assault Brigades and the 1st and 425th Assault Regiments—tens of thousands of troops, in all—marched through gaps in Russian defenses and, according to Ukrainian officials, liberated around 745 square km and 26 settlements. Mostly in Dnipropetrovsk Oblast but also in neighboring Zaporizhzhia and Donetsk Oblasts.

That is Kyiv's own accounting, and it is the high end. The Institute for the Study of War, which maps control from geolocated imagery, put the figure at roughly 627 square km across the Oleksandrivka direction and the northern Hulyaipole direction—while noting its own conservative method probably undercounts. Either number describes the largest Ukrainian territorial gain since 2023.

The Ukrainian gains helped to offset Russian gains around the last few free cities in eastern Ukraine's Donetsk Oblast. Between the start of February and the end of July, Russian regiments captured a net total of just 260 square km of Ukrainian soil, according to a tally by the Black Bird Group. It would've been more than 1,000 square km if those air assault and assault units hadn't been busy clearing the Russians from a wide swathe of the southeast.

According to our data, in July the net gains of the Russian armed forces in Ukraine were approximately 106km².

This is the fastest Russian advance since January, but their gains remain extremely limited. In July of 2025 the Russians captured nearly 5 times as much territory.

The Ukrainian counteroffensive kicked off on 29 January. Three days later, Elon Musk's Starlink bricked Russia's thousands of smuggled and stolen satellite terminals. Practically overnight, the Russians lost their best method for controlling small drones and guiding assault units across the disputed gray zone. Drones couldn't fly. Troops couldn't navigate.

Ukrainian commanders surely knew their communications advantage wouldn't last: the Russians would eventually adapt with new methods of command and control. Seizing the opportunity, Ukrainian paratroopers and assault troops pressed the attack. And in stark contrast to the usual assault tactics for both sides, the Ukrainians attacked in tanks and other armored vehicles, counting on the Russians' connectivity problems to clear a path for heavy forces.

The blackout was not the only thing working in Ukraine's favor. ISW credits the gains to five reinforcing factors: better operational planning, a campaign to suppress and destroy Russian air defenses, deeper strikes on Russian logistics, Ukrainian drone superiority at the tactical level—and the Starlink cutoff. But the cutoff is the one that arrived all at once, and it arrived just as Ukrainian armor was starting to move.

Despite many "analysts" doubting OPSEC, not too much information filtered from this offensive. Thus, let's get back inside to understand what happened

Mechanized assaults

Not all the vehicles got through. The assault troops lost one up-armored M-1 Abrams tank in early February. But by March, other assault forces M-1s were engaging Russian troops at point-blank range with their 120-mm main guns. After clearing a few disputed villages along a 45-km front between Dobropillya and Zelenyi Hai, the Ukrainians focused their maneuver and firepower on Komar, 12 km southeast of Zelenyi Hai.

The Ukrainians "started a slow and quiet offensive, with very few videos and small teams, during April and May," mapper Clément Molin recalled. The strict information security obscured the Ukrainian moves for all but the closest observers, allowing Ukrainian commanders to press their attacks without drawing too much attention—and risking a Russian countercounteroffensive.

By summer, the Ukrainians were within mortar range of Komar. Embarrassed Russian commanders resorted to sending out small teams on virtual suicide missions to plant Russian flags in disputed territory. The flags could create the impression of Russian control on terrain that, in fact, neither side controlled. "Russia is trying to intoxicate us with flag videos, which are meant to hide the real situation to both us and their command," Molin wrote.

The reality was that the Ukrainians had gained ground. A lot of it.

Announcing the results on 12 August, Ukrainian officials also claimed 9,550 Russian troops killed and more than 6,600 wounded—figures no independent body has verified. Former commander in chief Oleksandr Syrskyi, who planned the operation, said it proved the Ukrainian army "is capable not only of steadfastly holding its defences, but also of launching offensives, seizing the initiative, and liberating Ukrainian land."

But the momentum was unsustainable. As the Russians gradually restored command and control through the summer, the Ukrainians encountered more resistance. Now the gray zone is stabilizing again. Observer Moklasen predicted new Ukrainian commander in chief Maj. Gen. Mykhailo Drapatyi will order his corps and brigade commanders "to dig in positions, consolidate and strengthen more army corps" instead of continuing to attack.

After all, the Russians are pushing hard in Donetsk, and the resources the Ukrainians had devoted to the southeastern counteroffensive could boost the defensive effort in the east. Moreover, there are worrying signs the Kremlin may attempt another mobilization soon, potentially surging hundreds of thousands of fresh troops into Ukraine.

The Ukrainians may soon prioritize holding over attacking.

Russian troops are slowly marching toward and around Kramatorsk and Sloviansk, the last two big free cities in eastern Ukraine's Donetsk Oblast.

The Russians have a standard playbook for taking a Ukrainian city, and running it means doing two things at the same time. Along the nearly 100-km Kramatorsk front, they don't have the infantry to do both at once. Every time a Ukrainian brigade holds somewhere, the Russians have to move men to cover it—and something stalls somewhere else.

That strategy is simple in concept but difficult in practice. The idea is for Russian forces to advance along a city's under-protected flanks in order to put pressure on the main supply lines of the city's garrison. As the flank attacks squeeze the garrison's logistics, Russian infiltrators slip into the city, hoping to create a lodgement for follow-on forces.

The final assault through that lodgement comes late in the campaign, after the Ukrainians are already weakened by a lack of supplies.

Structural Deterrence

— Vitaly (@M0nstas) July 24, 2026

The strategy only works when the troops on the flanks and those in the middle work together. The former squeezes. The latter infiltrates. The problem for the Russian Center Group of Forces on the Kramatorsk front is that it's not squeezing and infiltrating at the same time. That delays the overall Russian advance and buys time for Ukrainian forces to dig in, reinforce, and hope for a miracle.

"Russian offensive planning at the operational level remains disciplined," mapper and analyst Vitaly explained. But only "on paper," Vitaly added. "Groupings are sequenced, axes are assigned, objectives are staggered."

"What the discipline is not is well-manned," the mapper wrote.

Vitaly reads one recent Russian adaptation as evidence of the shortfall rather than of cleverness. "I read the shift to two- and three-man infiltration teams on motorcycles and ATVs as less a sign of tactical innovation than of a manpower deficit that organization is straining to hide," he wrote.

Manpower shortages

Ukraine's manpower problems are well-known. Fewer observers appreciate that Russia struggles, too. Yes, the Russians still recruit around 30,000 fresh troops every month. In theory, that's enough new manpower to replace monthly losses.

But replacing casualties is not the same as resourcing a strategy. Ukraine's commander-in-chief Oleksandr Syrskyi put the Russian force in Ukraine at 721,300 at the end of June—a gain of only around 11,000 since late 2025, against Russian losses he estimated at 30,000 to 35,000 a month. Contract recruitment collapsed in the spring, falling by a third year on year, and Ukraine's foreign intelligence service counted 195,000 contract recruits by early July against an annual target of 409,000.

A Russian general, speaking anonymously to the investigative outlet IStories, put the requirement more starkly. To capture the rest of the Ukrainian-held Donbas, he said Russia would need to replace at least 55,000 to 60,000 casualties every month—roughly double what it recruits. That figure rests on a single unnamed source and should be weighed accordingly. But it describes the same gap Vitaly sees on the map.

When a Ukrainian brigade defeats one attack anywhere along the Kramatorsk front, it may compel Russian regiments to shuffle troops between units in order to quickly replace the losses. The shuffle may sap the combat power of a flanking or infiltration unit working along some other section of the front.

A weak flanking unit may not be able to keep up the pressure on enemy supply lines, perhaps imperiling the adjacent infiltration unit as it probes for the gaps in Ukrainian defenses that the flankers were supposed to help create. By the same token, weak infiltrators may find gaps in Ukrainian defenses, but fail to secure a lodgement—effectively wasting the efforts of the adjacent flankers.

"That gap keeps producing the same effect," Vitaly explained. The Ukrainian armed forces' "ability to hold separate sections of the front independently forces Russian formations to compensate for each other's failures, and that compensation creates new stalls."

Vitaly gave a name to the effect, and was careful about what he was not claiming. "I call it structural deterrence—not deterrence in the conventional sense, and not a doctrine, but the byproduct of asking an undermanned army to keep a sequenced plan on schedule."

A byproduct is not a defense, and it holds only as long as the Ukrainians can keep producing it. That requires synchronization of their own. Supplies and reinforcements must arrive when and where they're most badly needed. Air and artillery support should shift from sector to sector depending on the urgency of the local garrisons' needs.

All that is to say, the lack of synchronization that has slowed the Russians' march on Kramatorsk could eventually speed up the Russians' march—if and when the Ukrainians are the ones struggling to synchronize.

It's worth noting that the Russians aren't advancing fast toward Kramatorsk and Sloviansk, but they are advancing—especially from the northeast.

The Russians may not be perfectly synchronized. But they're clearly synchronized enough to grind toward the last free cities in Donetsk. Just very, very slowly.

For years, Russian troops probed the Ukrainian garrison at Mykolaivka in eastern Ukraine's Donetsk Oblast, sending in small teams of infiltrators for the defenders to hunt down. On 29 July, they stopped probing. "The Russians have begun an assault on Mykolaivka from the east," observer Thorkill reported, citing the local Ukrainian Telegram channel nikolaevka_online.

Russian assault groups are attacking the apartment blocks along the town's eastern edge. Mykolaivka sits 8 km east of Sloviansk, one of just two big free cities in Donetsk Oblast, and taking it is the precondition for any Russian siege of the city. "The situation is deteriorating," nikolaevka_online warned.

Mykolaivka is "the eastern gateway to Sloviansk," according to mapper Clément Molin. The Russian offensive in Donetsk aims to lay siege to and ultimately capture Sloviansk and neighboring Kramatorsk, which together are still home to nearly 100,000 people despite hundreds of thousands of others having fled.

For months, the situation on the Sloviansk front has been deteriorating

A Ukrainian garrison anchored by the 81st Airmobile Brigade has defended Mykolaivka for years. But the garrison has been struggling to interdict every team of Russian infiltrators—and now the infiltrators have company.

The sector is an exception to a mostly frozen front. Russian troops captured 106 square km of Ukrainian territory in July, according to the Blackbird Group—the fastest Russian advance since January, but a fifth of what the Russians seized in July 2025. Blackbird reads the figure as evidence Russia has largely exhausted its offensive options; in June, Russian forces lost 9 square km on net. The slow average along the 1,200 km gray zone belies much faster movement in a handful of sectors, and east of Sloviansk is one of them.

Expect a long, hard fight in and around the ruins of Mykolaivka. "It is highly unlikely that the battle for Sloviansk will begin this year, not least because the fighting in Mykolaivka is likely to be prolonged," Molin explained.

According to our data, in July the net gains of the Russian armed forces in Ukraine were approximately 106km².

This is the fastest Russian advance since January, but their gains remain extremely limited. In July of 2025 the Russians captured nearly 5 times as much territory.

Tough terrain

The geography is difficult for both the defenders and the attackers. The Donets Canal, which abuts Mykolaivka on the west, "aids the Ukrainian defense just as much as it facilitates the Russian offensive," Molin noted. To reinforce the 81st Airmobile Brigade in and around Mykolaivka, Ukrainian troops must cross the canal while under Russian fire. "Massing troops there is a highly complex undertaking," Molin warned.

But the Russian army will face the same challenge if and when it marches through Mykolaivka. "Crossing the canal, particularly around the Sloviansk power plant and its network of waterways, will come at a very high cost, especially given the extensive fortifications the Ukrainians have built in the area over recent months," according to Molin.

In other words, the 81st Airmobile Brigade has fallback positions on the near side of the Donets Canal. If the brigade can't hold Mykolaivka, maybe it can hold the canal—and delay if not halt further Russian advances toward Sloviansk.

The Ukrainians would prefer to hold in Mykolaivka, of course. But it's looking increasingly dire. The Russians appear to be accumulating in the seasonal homes, or "dachas," on the northeastern outskirts of Mykolaivka. "It is difficult to say at this point how many Russian soldiers have infiltrated there," Thorkill wrote. "However, their very presence has forced the command of the 81st Air Assault Brigade—responsible for the city's defense—to secure with patrols."

The Ukrainian brigade is trying to build a wall of infantry and drones between the dachas and a key road intersection that can carry defenders and attackers across central Mykolaivka.

But the 81st Airmobile Brigade is outnumbered, probably badly so. For the first two years of the wider war, the brigade could count on help from the 54th Mechanized Brigade, which clung to the 81st Airmobile Brigade's right flank.

While the 54th Mechanized Brigade still registers on many maps of the gray zone, in fact it's barely there. "Various snippets of information indicate that the 54th Mechanized Brigade—longtime right-flank neighbor of the 81st Brigade—was completely withdrawn from the front between June and July 2024 and sent to the deep rear," Thorkill wrote. East of Sloviansk, "only its drone group remained."

"The unit had long been a brigade in name only," Thorkill noted. So the 81st Airmobile Brigade fights mostly alone, for now—defending the gateway to Sloviansk.
