Ukraine's Defense Forces advanced more than 15 km through underground utility tunnels into Russia's rear on the Kupiansk axis in Kharkiv Oblast, the Khartiia Corps of Ukraine's National Guard reported on 22 October. The corps called it Operation Veles. The underground advance was paired with attacks on the surface and drone strikes, hitting Russian forces from two directions, the corps told Militarnyi.

Russian troops have repeatedly crawled through gas pipelines around Kupiansk to get behind Ukrainian lines, even after Ukraine reported confident control of the city in February. This time, Ukraine went underground itself. The operation took away Russia's chance to get into Kupiansk's rear, the corps said.

The corps reported more than 30 Russian soldiers captured and Russian losses of more than 100. Militarnyi, citing the unit, put the number of Russian troops killed at over 100.

Khartiia studied how Russian troops moved through pipes before going underground itself, the corps commander, Brigadier General Ihor Obolenskyi, said.

"We watched how the enemy works underground and studied how they do it. The Russians intended to use gas pipelines to get into the rear of our troops. So we went underground ourselves. We anticipated the enemy's actions and mastered the tactics of underground combat," he said.

For the operation, troops trained physically and psychologically to fight in confined spaces, sappers and engineers prepared the underground route, and special communications, navigation, silent logistics, and life-support systems were put in place, Khartiia told Militarnyi. The operation was named after Veles, the Slavic pagan god of the underworld.

Khartiia's brigade, the R.U.H. assault regiment, the Lava drone regiment, the Achilles drone brigade, and units of Ukraine's military intelligence, including the Freedom of Russia Legion and the Russian Volunteer Corps, took part, the corps said.

Russia has used pipelines to infiltrate before

By September 2025, Russian forces had used pipelines to move troops behind Ukrainian lines three times, Ukrainian monitoring project DeepState reported on 12 September 2025. The first was in Avdiivka, the second near Sudzha, and the third near Kupiansk, where groups crossed the Oskil River through a gas pipe.

Near Sudzha in March 2025, Russian special forces walked through a pipeline that until recently had carried Russian gas to Europe, the Associated Press reported. A pro-Kremlin blogger claimed they covered about 15 km and that some spent several days inside.

Russian troops kept using the pipeline near Kupiansk this year. On 27 September, Khartiia's reconnaissance drones recorded Russian forces leading nine civilians, including children, elderly people, and a person on crutches, through the gas pipeline out of the Kupiansk community. Men of military age in civilian clothes walked alongside them, and the corps believes they were Russian soldiers using the group as cover to withdraw. Ukrainian troops held fire because of the civilians, the corps said, adding that the case has been documented for a war crimes investigation.

Why the war is moving underground

Drones, constant surveillance, and AI-assisted targeting have made the battlefield surface transparent and deadly, argue John Spencer, chair of urban warfare studies at West Point's Modern War Institute, and Col. Drew Craig, principal military engineering staff officer at NATO's Allied Rapid Reaction Corps. In an August analysis, they write that soldiers in Ukraine describe a "death zone" of some 30 km, where moving above ground can draw an attack within minutes. When firepower makes the surface too dangerous, armies have historically gone underground, as they did in World War I and Vietnam, and more recently in Gaza and Lebanon.

"Armies that cannot survive above ground must adapt below it," the authors write.

Fighting in tunnels brings its own requirements, the authors write: detecting the enemy by sound and vibration, and specialized unmanned systems that cannot rely on GPS or stable radio links. Long stretches underground also take a severe psychological and physical toll on soldiers.

Western militaries are not ready for this, Spencer and Craig write. No NATO partner maintains even general capabilities for large-scale underground warfare, and US and British efforts focused mainly on detecting and clearing tunnels rather than occupying and operating in them.

Russian forces are preparing to resume mechanized assaults in southern Ukraine after a pause of several months and are moving armored vehicles toward areas where they plan to launch offensives, Anastasiia Shevchenko, deputy spokesperson for the Southern Forces Grouping, told Ukrinform on 22 October. The Huliaipole axis remains the hottest in the Southern grouping’s zone, with 10 to 20 combat engagements reported on an average day, she said.

On the Huliaipole axis, one of Russia’s largest force groupings is fighting Ukrainian forces, comprising units from several Russian combined-arms armies, the spokesperson says. Over the past week, as the weather worsened, Russian forces began local assaults there with infantry, motorcycles, and armored vehicles, seeking to break through toward Zaporizhzhia and blockade the city, Ukraine’s 7th Air Assault Corps reported, adding that the area is one of Russia’s key priorities in southern Ukraine. Russia has used fog this way before: last November, Russian troops moved under its cover to avoid detection by Ukrainian drones as they advanced on Huliaipole, the Institute for the Study of War assessed.

Russian forces have abandoned large-scale assaults across a broad front and are attempting to infiltrate Ukrainian positions in small groups. They periodically use motorcycles and quad bikes for assaults, Shevchenko said, adding that these vehicles are fast and maneuverable.

However, Russian forces should not expect to advance unimpeded, the spokesperson noted. Ukrainian units control Russian supply routes and systematically detect and strike Russian personnel and equipment while they are still moving toward their launch positions, she added.

“Specifically, speaking in numbers, since the beginning of October alone, units of the Southern Forces Grouping (Forces) have destroyed more than 3,000 occupiers and 1,300 pieces of weapons and military equipment. Thus, the enemy is suffering significant losses in the operational zone of the Southern Forces Grouping (Forces),” the spokesperson concluded.

Ukrainian drones disrupt Russian logistics

Russian forces had stopped using military vehicles because Ukraine’s unmanned systems forces controlled their logistics, Shevchenko said in comments to Ukrinform on 16 September. Ukrainian drones spotted Russian troops and equipment in time and struck them mostly on their routes of advance, she said.

Ukrainian air strikes destroyed bridges near Polohy in Zaporizhzhia Oblast, complicating Russian supply operations along the Huliaipole axis, Ukraine’s 7th Air Assault Corps reported on 21 September. Russian forces had used these bridges to move personnel, heavy equipment, and ammunition for their offensive toward Orikhiv. Disruptions to logistics have forced Russian units to rely more on motorcycles, which are more vulnerable to Ukrainian strikes, the corps said.

Russian forces are also expected to use fog and rain as cover for assaults, Mykola Zinko, deputy commander of the unmanned systems battalion of the 5th Assault Brigade, said on 19 October. Russia has brought up reserves, and its heavy equipment will move out under the fog, he said.

Intercepting a jet-powered Geran can cost anywhere from $2,000 to $4 million depending on the weapon used. Cheap interceptor drones are the only option that keeps air defense affordable, the foundation of Ukrainian top war volunteer Serhii Sternenko said on Telegram.

Russia’s jet Gerans now carry every characteristic of a small cruise missile, and Russians keep raising their speed in answer to each Ukrainian countermeasure. Former commander-in-chief Valerii Zaluzhnyi has framed the shift bluntly: an expensive Cold War missile has become a cheap weapon fired in bulk, and the drone is now “a missile in all but name,” affordable to any side, not only wealthy countries.

Sternenko heads a charitable foundation that has purchased 291,502 FPV drones, which have helped Ukraine’s military down more than 12,954 aerial targets. Also, has advised the team of former Defense Minister Mykhailo Fedorov.

Three ways to kill a jet Geran, and what each costs

The foundation laid out the price of each method:

• Aircraft (F-16, MiG-29, Su-27, Mirage 2000): $25,000 to $1.2 million per kill. Effective, but the stock of missiles is critically low, and some air-to-air types are no longer being replenished.
• Surface-to-air and shoulder-fired systems (IRIS-T, NASAMS, Vampire, Avenger): about $30,000 to $4 million. Good for shielding key sites, but a missile capable of reaching a jet Geran at 6 to 7 kilometers costs $0.5 million to $4 million.
• Interceptor drones (makers undisclosed): from $2,000. Cheap, with trained operators ready, but not yet scalable.

Why the cheapest option is the one that matters

No single tool is enough, the foundation stresses. Downing jet Gerans still needs aircraft, small aviation and missile systems together, but it is the interceptors that make the defense affordable, taking out the cheaper Shaheds and saving costly missiles for targets nothing else can reach.

The foundation says it has found a way to counter drones that already match small cruise missiles, working with Ukrainian manufacturers, without disclosing details. The method is far cheaper than other ways of downing jet Gerans and significantly strengthens air defense, it says, as part of a wider Ukrainian push to field interceptor drones fast enough to catch Russia’s fastest weapons.

The commander of an interceptor battalion in Ukraine’s 3rd Army Corps said his unit destroyed several thousand Russian aerial targets during Operation Vivaldi, ArmyInform, the Defense Ministry’s news agency, reported on 21 October.

Operation Vivaldi is a Ukrainian counteroffensive north of Lyman in Donetsk Oblast, where the 3rd Army Corps has reported liberating settlements. In its third phase, Ukrainian forces reclaimed five settlements and expanded their gains to 176 square kilometers. Strikes on Russian logistics and electronic warfare likely neutralized Russia’s drone defenses before Ukraine sent in armor, the Institute for the Study of War assessed.

The commander, who uses the callsign “Betsyk,” leads the interceptor battalion of the 1030th Anti-Aircraft Missile-Artillery Regiment “Aquila,” part of the 3rd Army Corps. He said Russian forces deployed large numbers of reconnaissance drones to locate Ukrainian positions after the corps began advancing.

Betsyk named Zala, Orlan, Supercam, Merlin, and Knyaz Veshchiy Oleg among the reconnaissance drones used by Russian forces.

Russia also brought in reinforcements and units operating strike drones, including first-person-view (FPV) quadcopters, Molniya fixed-wing FPV drones, and Lancet crews, he said. At one stage, Russian forces deployed crews from their Rubicon drone unit to disrupt the advance, but the move did not change the situation.

Betsyk said his battalion’s work deprived Russian forces of the ability to strike Ukrainian troops and track their movements.

Jet-powered Shaheds: speed is the main challenge

The regiment also works against Russian strike drones heading for targets behind the front line. Betsyk said interceptor crews had destroyed some jet-powered drones, but not in significant numbers.

The main difficulty is speed, he said. Interceptor drones need to reach 500–600 km/h to intercept Russian jet-powered attack drones, according to Betsyk.

For now, the regiment mainly uses conventional air-defense systems against these targets: self-propelled anti-aircraft systems, surface-to-air missile systems, and portable surface-to-air missile systems. Betsyk said these systems were historically designed to engage jet-powered targets.

He compared the current challenge with the early use of piston-powered Shaheds. Those drones initially posed a serious threat but later became easier for Ukrainian air defenses to counter. Russia has largely stopped using piston-powered Shaheds on most fronts since summer, he said, but continues to use piston-powered Gerbera drones, which are relatively cheap and can partly exhaust Ukrainian air defenses. The main drones Russian forces use now are jet-powered Shaheds, he said.

Betsyk expects Russian forces to adapt if Ukraine fields effective interceptors against jet-powered drones. They will seek ways to evade the interceptors, increase speed, improve navigation, and change their tactics, he said. However, he added that the battalion had not observed a major evolution so far and did not expect the drones’ speed to double.

What the corps says Vivaldi achieved

Separately, 3rd Army Corps commander Andrii Biletskyi said Ukrainian forces retook 277 square kilometers and 16 settlements during Operation Vivaldi, Ukrainska Pravda reported. Biletskyi also said Russian losses exceeded 8,000 personnel, according to ArmyInform. These figures are Ukrainian claims and have not been independently verified.

Russia’s Rubicon drone unit, which is sent to hunt Ukrainian drone pilots, was not used to being hunted itself, Brigadier General Andrii Biletskyi told journalists on 19 October. He was summing up Operation Vivaldi, which his Third Army Corps fought in northern Donetsk Oblast from May to mid-October. Once its pilots realized they were being killed, Rubicon’s morale dropped sharply, he said.

Russia has fought for 12 years to take all of Donetsk Oblast, and Sloviansk and Kramatorsk anchor the fortress belt of cities Ukraine still holds there. Vivaldi retook 277 km² in northern Donetsk Oblast. Biletskyi says it destroyed Russia’s bridgehead on the Chornyi Zherebets River and forced Moscow to drop its plan to bypass Lyman from the north and encircle the two cities. On that front, the Third Corps had flagged Rubicon, Russia’s elite drone unit, as a threat.

Hunting the hunters

Once a Rubicon position was found, the Third Assault Brigade and the KRAKEN drone regiment committed any number of FPV and bomber drones to destroy its crews, Biletskyi said.

The brigade’s commander, Yaroslav Levenets, said his troops prepared for Rubicon’s arrival and concentrated on killing its pilots. He gave no details.

“Not stable in defense,” Levenets said of Rubicon’s troops.

They dislike sitting in trenches, he said, and under pressure they grow nervous and change positions.

Named for four seasons

Biletskyi said the name was chosen at the very start of planning, in winter 2025–2026, many months before the operation began. The original plan had four stages, one for each season, and later grew to slightly more, ArmyInform reported.

When he first unveiled the operation in September, he put it this way:

“Vivaldi, as is known, has four seasons. And this is only the first one.”

He credited two planners, known by the call signs Yurist and Leshyi. Leshyi, an assault soldier wounded seven times who later moved to staff work, was killed. Yurist was seriously wounded.

A new hand at the Third Corps

Major Dmytro Rohoziuk is now acting commander of the Third Army Corps, the corps press service said on 20 October. The press service said the move is not a transfer, and Biletskyi keeps his formal post as corps commander while he leads the “Center” grouping of the Third, 11th, and 19th corps.

Rohoziuk took over the 60th Mechanized Brigade in October 2025. Its previous commander was arrested in January after the State Bureau of Investigation accused him of embezzling about $1 million in weapons procurement. The brigade fought in all four phases of Vivaldi and retook Kolodiazi without street fighting.

Biletskyi also declined command of the Ground Forces, which oversee mobilization.

“There’s no point taking on something you don’t truly believe you can improve,” he said.

Biletskyi’s count

Russian losses in Vivaldi topped 8,000 troops, and about 270 Russian soldiers were taken prisoner, Biletskyi said. More than 20 officers surrendered, including a chief of staff and three company commanders.

The territory matters less than disrupting Russia’s strategic plan, he said. Russian forces still press toward Dobropillia, where Ukraine is counterattacking.

Reports that SpaceX temporarily restricted its satellite internet service for Ukraine’s armed forces have generated serious concern in Kyiv and among the country’s allies. SpaceX operates the civilian Starlink system and its lesser-known military-grade counterpart, called Starshield. But many news stories leave an important question unanswered: what does a Starshield “slowdown” mean on the battlefield? […]

The post Why Starshield’s slowdown really hurts Ukraine appeared first on Asia Times.

Ukrainian infantry encircled and retook the village of Kolodiazi north of Lyman without getting drawn into street fighting, while a drone battalion kept the sky above them shut, the battalion’s chief of staff told Suspilne on 18 October. The village fell during the fourth and final phase of Operation Vivaldi, Ukraine’s counteroffensive in northern Donetsk Oblast.

For years now, Russia has aimed to seize Lyman and cross the Siverskyi Donets River. It needs this area to encircle Ukraine’s fortress belt of Donetsk Oblast cities from the northwest, ISW assesses. Vivaldi’s four phases retook 277 km² and 16 settlements on that approach, and a veteran of the operation has said Ukraine’s assault troops suffered more than ten times fewer casualties than Russian forces doing it.

Drones over the infantry

The 60th Mechanized Brigade fought in all four phases of Vivaldi and took Kolodiazi in the last one, said the chief of staff of the brigade’s Fatum unmanned systems battalion, callsign Krash.

“Our task, as an unmanned systems battalion, was to escort and ‘close’ the air in front of our infantry to make it impossible for the enemy to hit it. To suppress all the firing assets possible,” he said.

The brigade’s 3rd Mechanized Battalion, the main striking force, encircled Kolodiazi and retook it without getting drawn into street fighting, Krash said. The 1st Mechanized Battalion kept Russian reinforcements out of the area, while drone crews suppressed artillery, hit supply runs, and worked against Russian drone operators.

500 troops and 200-plus vehicles

The drone battalion killed or wounded about 500 Russian troops during the fourth phase and struck Russian armored vehicles, trucks, and motorbikes, its chief of staff said.

“More than two hundred pieces of various equipment: Grad and Uragan multiple rocket launchers, various armored vehicles, tanks, armored combat vehicles. Most of all motorbikes and quad bikes, there the count runs into the hundreds. This is our enemy’s main logistics tool,” he said.

Ghost villages

The villages retaken in northern Donetsk Oblast are nearly empty of civilians, Krash said.

“It’s very typical for de-occupied settlements: these are ghost towns. You can see right away where the occupier stepped. All the settlements are under the control of the Third Army Corps, our forces stand there and prevent enemy infiltration. But civilian life in these towns is either absent or very scarce,” he said.

Third Army Corps commander Brigadier General Andrii Biletskyi reported Kolodiazi’s liberation, along with Zelena Dolyna and Lypove, when he summed up Vivaldi’s fourth phase, which secured 101 km².

A recent breakthrough in airborne drone control has offered a tangible glimpse into the future of US air combat, signaling the US Air Force’s accelerating push to integrate autonomous wingmen alongside frontline fighters.

White House officials instructed Pentagon leaders to limit Starshield, SpaceX’s military-grade satellite service used by Ukrainian forces, Reuters reported on 15 October, citing three officials. The report came a day after a senior US official told Axios the Trump administration had nothing to do with the alleged Starlink restrictions.

Ukrainian forces rely on US-controlled satellite technology for battlefield operations and for intercepting Russian drones aimed at Ukrainian cities, so the latest restrictions have raised questions about how reliably they can depend on it.

Senior US official denies president requested restrictions

Asked about the order, a senior US official replied, “No such request was ever made by the president.” The White House did not respond to questions about whether other administration officials might have made the request.

Ukrainian officials contacted the White House, State Department and Pentagon on 13 and 14 October and were told it was a White House decision

European allies question Starlink restrictions

European officials raised concerns about the restrictions. German Foreign Minister Johann Wadephul criticized the throttling and said Ukraine must continue to receive full support, Spiegel reported on 15 October. Wadephul said Germany had questions for the US, noting that Germany finances part of the Starlink technology used in Ukraine.

On 16 October, UK Defense Secretary Wes Streeting said US Defense Secretary Pete Hegseth had assured him in a face-to-face meeting that Starlink was back up and running, the Guardian reported. However, a Ukrainian Defense Ministry source said that military-grade terminals were working in motion again, but only at speeds of up to 160 km/h.

New data-speed restrictions disrupted drone missions

The military Starshield package previously had no data-speed restrictions, Ukraine’s 7th Rapid Response Corps told Novynarnia. Ukrainian officials said that after the restrictions were imposed, terminals disconnected when drones exceeded 160 km/h and sometimes at 80 km/h.

The Corps also reported 10–20-second connection drops at 110–120 km/h on the Huliaipole front, which made drones harder to control. One unit had to cancel some missions.

The restrictions came as US President Donald Trump pressed Kyiv to stop striking Russian oil refineries, blaming them for soaring energy prices ahead of November’s midterm elections. Ukraine suspects SpaceX imposed the restrictions to pressure Kyiv over the refinery strikes, but that motive has not been confirmed.

The drone has become the signature weapon of the Russo-Ukraine war. On any day in Ukraine, tens of thousands of drones are out hunting the battlefield for targets. These could be individual enemy soldiers or vehicles, or they could be larger targets such as depots, headquarters, bridges or power plants. Yet, this drone war has […]

Ukraine’s operation to strike Russian targets at operational and strategic depth is continuing, Unmanned Systems Forces Commander Robert “Madiar” Brovdi said. He listed data centers, military and strategic sites, and energy hubs “deep in the swamps,” his usual name for Russia.

The fresh statement lands amid fears that a Starlink disruption could break front-line operations.

Overnight into 14 October, the 7th Air Assault Corps said the faster StarShield military package, an advanced version of Starlink that its units depend on, had been throttled, halting a series of missions. Against that backdrop, Brovdi says his branch’s strikes are not falling.

“A serious brawl is underway in conditions of significantly worse weather, drizzle, fog, and precipitation,” Brovdi says, underscoring that the pace held through conditions that usually ground drones.

Over the first two weeks of October, the drone branch verified 7,306 Russian soldiers killed or wounded, up 59.45% on the same period in August and 24.65% in September, he writes on his Telegram page, calling the trend the opposite of de-escalation.

Where the killing climbs fastest, and who is doing it

One sector stands out above the rest. On the Dobropillia-Pokrovsk axis, in the zone of the Azov group, the branch’s drones accounted for 3,221 Russian losses in the first two weeks of October, a 102% jump on August and 42.5 percent on September, Brovdi reports.

The figures cover only the drone branch and are verified in the military’s Delta, the video fixation system, he stresses, so the full count of Russian losses across all Ukrainian forces can be much higher.

The scale of a campaign that will not slow down

The numbers behind the claim are large. Over the first two weeks of October, the branch flew 124,500 combat missions, strike and reconnaissance, and hit 32,172 Russian targets, of which manpower was 22.7%, by his count.

That works out to about 2,298 Russian targets a day, he adds, the kind of tempo that makes any talk of a lull on the front hard to square with what his drones are recording. The deep-strike half of that campaign has grown 1,150% over 2026, reaching military-industrial and energy sites far inside Russia, according to Euromaidan Press.

Ukrainian officials contacted the White House, CIA, and Pentagon after the restrictions, which Ukraine says affected both Starlink and Starshield, Axios reported on 14 October. A senior US official told Axios the Trump administration had nothing to do with the restrictions. On the same day, Elon Musk said on X that Starshield systems are owned and controlled by the US government, and that any speed or usage limits are decided by the US military and ultimately the president.

The restrictions could affect Ukraine’s ability to intercept Russian attack drones and carry out mid-range strikes against Russian forces and military targets in occupied Ukrainian territories. A speed cap of 160 km/h was insufficient to intercept some jet-powered drones, an unnamed Ukrainian official told Axios. Ukrainian officials told Axios they suspect SpaceX imposed the restrictions to pressure Kyiv to accept US President Donald Trump’s demand to stop striking Russian oil refineries, though the motive remains unconfirmed. But Starlink does not work inside Russia, and the drones attacking Russian oil facilities use other communications systems, according to Reuters.

What Musk and the White House said

Musk did not directly address the throttling, Axios noted. Starlink, he wrote, “is a commercial service owned and controlled by SpaceX,” limited to civilian or defensive use.

White House officials told the Ukrainians they don’t have control over SpaceX, two sources told Axios. One said the administration would reach out to SpaceX to figure out what happened. The White House did not immediately respond to Axios’s request for comment.

How the cap disrupted drone missions

Presidential adviser Serhii Beskrestnov said on 14 October that SpaceX had imposed a 160 km/h limit on Starshield’s “military package” overnight without warning. Ukraine’s 7th Rapid Reaction Corps said mid-range strike drones must reach high speed quickly and that an unstable connection “will make it impossible to launch such aircraft or use them as intended.” One unit on the Huliaipole front had to cancel some missions, the corps told Novynarnia.

Ukrainian officials told Axios the system turned off when drones exceeded 160 km/h, and sometimes 80 km/h, before service was partially restored on 14 October. The Defense Ministry said SpaceX continues to restrict Starlink to 160 km/h and that it remains in communication “with partners and SpaceX regarding stable service conditions and the prevention of sudden restrictions,” Axios reported.

A diesel deal

The restrictions followed Trump’s 9 October deal with Russian President Vladimir Putin easing sanctions on Russian diesel. A day later, Trump told reporters: “We said you could do whatever you want to Russia, don’t hit the refineries,” the Kyiv Independent reported.

Russia’s drone and missile attacks on Ukraine’s population and infrastructure continue to dominate coverage of the conflict. But on the ground, Ukraine has been making significant, if still limited, gains. In mid-September, Ukraine formally announced the existence of Operation Vivaldi, which has retaken territory near Lyman and disrupted a Russian advance toward the fortified cities […]

The post Operation Vivaldi: Ukrainian gain on a drone-filled battlefield appeared first on Asia Times.

A key component of Ukraine's communications network was partially disabled on Wednesday. The Starshield satellite network, funded by the Pentagon and operated by Elon Musk's SpaceX, was not operating at full capacity, hampering communications within the Ukrainian military. Liz Landers reports and Amna Nawaz discusses the developments with retired U.S. Navy Rear Adm. Mark Montgomery.

Ukraine has completed its Operation Vivaldi, aimed at protecting its fortress belt cities of Donetsk Oblast, which helped Kyiv preserve the region from Russian occupation for 12 years. Brigadier General Andrii Biletskyi, the commander of the Third Army Corps behind the operation, has reported that the fourth phase secured 101 km² of territory. Among the latest achievements is the liberation of three settlements—Zelena Dolyna, Lypove, and Kolodiazi.

The operation's main objective was to move Ukrainian troops into more advantageous defensive positions, Biletskyi said in the first days after the operation was made public. Vivaldi has now summed up the results of all four phases: Ukraine has established full control over 16 settlements, liberated 277 km² of territory, and inflicted 8,000 casualties on Russian forces.

Ukraine worked against Russia's deadline

During Operation Vivaldi, Ukrainian forces have prevented Russian troops from outflanking the Sloviansk-Kramatorsk agglomeration and cutting the Kharkiv–Sloviansk highway, a key supply route for Ukraine’s forces in Donbas, Biletskyi says.

“We thwarted the offensive of the Zapad grouping and forced it to redeploy some units of the 1st Tank Army, which eased pressure on Kupiansk-Vuzlovyi,” Biletskyi announces.

Previously, the Institute for the Study of War noted that Russian President Vladimir Putin was confident that Russian forces would be able to seize the entire Donetsk Oblast by the end of 2026 — the Kremlin’s latest deadline for achieving this goal.

Ukraine’s military was on a mission to prevent this.

Season one: clearing russian infiltration groups

On 15 September 2026, Ukraine’s Third Army Corps announced Operation Vivaldi in northern Donetsk Oblast. During the first phase, Ukrainian troops cleared Russian groups from 75 km² of territory and liberated another 10 km².

The Third Army Corps said it had struck Russian supply routes and fuel infrastructure, prompting Russia to relocate its fuel and lubricant reserves to Voronezh Oblast. According to the corps, Russian forces lost around 1,500 troops, more than 12,000 drones, and hundreds of pieces of equipment.

Season two: liberation of Shandryholove and Derylove

On 20 September, the Third Army Corps reported the liberation of Shandryholove and Derylove and the establishment of full control over Drobysheve.

During the second season, Russian forces lost another 800 troops, bringing their total losses across the first two seasons to more than 3,000, according to the corps.

During the first two seasons of the operation, Ukrainian troops and attached units regained control of 125 km² of territory, including 50 km² that had been fully liberated.

The first phase of Vivaldi involved eliminating Russian groups that had infiltrated Ukrainian positions, explained the commander of a battalion in the 125th Brigade, callsign Darwin, per ArmyInform. After clearing those groups, the Defense Forces moved on to the operation’s second phase, using reconnaissance drones to detect Russian forces, he added.

For this, Ukraine used UAVs and ground robotic systems.

“The Third Army Corps was the first in the world to begin deploying ground robotic systems by air. Our heavy bombers deliver kamikaze ground robotic systems more than 10 kilometers behind enemy lines,” Biletskyi noted.

Season three: advances near Novе and Ridkodub

On 28 September, the Third Army Corps reported the liberation of Nove, Ridkodub, and Katerynivka and the restoration of control over Karpivka and Novomykhailivka. Ukrainian forces regained another 51 km² of territory, bringing the total area liberated since the start of the offensive to 176 km². Russian forces lost around 2,000 troops, and more than 250 were taken prisoner, the corps said in its summary of the operation’s third phase.

“The Russians were convinced that the main axis of attack was Shandryholove–Zelena Dolyna. This led it to squander its reserves in counterattacks along that very axis. The Russians slept through the actual strike, which was focused on capturing Nove,” Biletskyi said.

Operation Vivaldi aimed to disrupt Russia’s plans in Donetsk Oblast

The need for Operation Vivaldi arose amid Russian attempts to encircle Ukraine’s fortified belt in Donetsk Oblast. Ukrainian forces conducted preparatory efforts aimed at degrading Russia’s offensive capabilities, including strikes on Russian drone operators, the Institute for the Study of War reported on 9 October.

Ukrainian counterattacks in the Lyman direction and east of Sloviansk and Kramatorsk were intended to complicate Russian efforts to seize the fortified belt in Donetsk Oblast, the report noted.

The corps advanced gradually, reclaiming small areas instead of attempting a large-scale breakthrough.

Ukraine’s presidential adviser Serhii Beskrestnov said SpaceX had imposed a 100 mph (160 km/h) speed limit on its military Starshield service overnight into 14 October, disrupting several missions without warning Ukraine’s defense forces.

Ukraine’s forces use Starlink-connected drones to strike Russian positions and logistics, including targets behind the front line. Unlike earlier restrictions introduced at Kyiv’s request to stop Russian forces from exploiting Starlink, the latest change reportedly targets the military Starshield service and was imposed without warning Ukraine’s military.

What the new restriction covers

Beskrestnov wrote that the restriction applies to the “military package” of Starshield services. He said the move “obviously cannot be a coincidence” and was connected with the “current political situation,” but did not explain what he meant.

Activist Serhii Sternenko, a former adviser to Ukraine’s defense minister, reported that connections began disappearing at speeds above 160 km/h. He suggested SpaceX had acted at the Trump administration’s request but provided no evidence. Starlink does not work inside Russia, and the drones hitting Russia’s oil industry use other means of communication, Reuters noted. Sternenko added that the ordinary satellite terminals were still working.

Later on 14 October, Sternenko wrote that, according to military reports, restrictions had been tightened further, with connections starting to drop at 60–70 km/h. Beskrestnov later warned that the restriction also hits Starlink-linked interceptor drones, which he called Ukraine’s most effective current defense against jet-powered Shaheds.

Front-line units report dropped connections

Ukraine’s 7th Rapid Reaction Corps confirmed the disruptions in a statement to Reuters. The corps’ press service told Novynarnia that its units on the Huliaipole front began experiencing problems overnight. The corps said the change affected drones controlled through Starlink in flight and concerned Starshield’s data-transmission speed, which it said had previously been unrestricted.

The corps said connections could disappear for 10–20 seconds at movement speeds of 110–120 km/h, complicating drone control. Flying slower creates its own risk, it said, because “slower targets become more vulnerable to being hit by the enemy.”

Some high-speed drones, particularly mid-range strike models, must reach high speed quickly, the corps said. An unstable connection “will make it impossible to launch such aircraft or use them as intended.” Since the start of the day, one unmanned systems unit on the Huliaipole front had to cancel some missions because of connection problems, the corps said.

Earlier limits came at Kyiv’s request

In late January, SpaceX began restricting Starlink in Ukraine at Kyiv’s request after Russian forces started mounting terminals on strike drones. After Russian drones struck a passenger train in Kharkiv Oblast on 27 January, Beskrestnov, then an adviser to the defense minister, suggested one of them may have been controlled via Starlink. In early February, Ukraine introduced a whitelist under which only registered terminals could continue operating. Beskrestnov called the earlier countermeasures “temporary” and “emergency.”

SpaceX had not publicly commented on the restriction, and Ukraine’s Defense Ministry was looking into its cause, Radio Svoboda reported. Polish Foreign Minister Radosław Sikorski asked Elon Musk on X whether he was “playing politics with your products again,” adding: “As your European customers, we are watching you.”

Russia suffered vastly more casualties than Ukraine in September, a senior NATO military official told Bloomberg. Ukraine’s General Staff put the month’s Russian toll only slightly lower.

September’s toll lands on a recruitment system that was already falling short. Ukraine’s military intelligence (HUR) estimated that Russian losses outran new contracts in June and July, when monthly losses ran lower. In August, Ukrainian President Volodymyr Zelenskyy, citing military intelligence, warned that Russia is preparing a mass call-up after its parliamentary elections. That vote ended on 20 September.

Where the numbers come from

Russian casualties passed 50,000 in September, up to 28,000 of them killed, the official said. Ukraine’s losses over the same month came to about 5,000, according to the official, who spoke on condition of anonymity. Russia does not release casualty figures, Bloomberg noted. In late August, Pavlo Palisa, deputy head of Ukraine’s Presidential Office, put Russia’s July losses at 43,000 killed and wounded. Bloomberg could not confirm his figures.

To push forward, Russia keeps feeding troops into “kill zones,” the official said. These are stretches of ground saturated with armed drones, mines, and artillery fire. Maksym, call sign Rumyn, is a deputy company commander in the 46th Airmobile Brigade’s drone battalion. In April, he said the zone once ran 3–5 km deep and is now several times larger.

Rising stakes for Moscow

Russia’s defense spending is expected to near $199 billion this year, Bloomberg reported, citing two sources close to the government. That is about 40% above the plan the government set in late 2025.

Russian President Vladimir Putin would struggle to wind down the invasion without a political cost, Martin Jäger said last week. He heads Germany’s Federal Intelligence Service (BND).

Units of Ukraine’s Unmanned Systems Forces have killed or wounded more than 100,000 Russian troops since the start of 2026. That is more than 150,000 since the force was created on 11 June 2025, the force said on Telegram.

Drones have become the deadliest weapon of this war, accounting for about 96% of Russia’s battlefield casualties earlier this year. These hits are verified on video in the military’s Delta system, which is how the force counts only the losses its own pilots confirm.

“Behind these figures is the daily combat work of our soldiers, thousands of sorties, precise strikes, and the constant improvement of unmanned technologies,” Ukraine’s Unmanned Systems Forces said.

Each strike reduces Russia's combat potential and reflects the coordinated work of the force’s units, it added.

A toll that keeps climbing

Overall, drone branches of the Ukrainian Army had carried out more than 1 million verified strikes on enemy targets since January, killing or seriously wounding about 193,500 Russian troops, Ukraine’s Defense Ministry reported in July.

Those strikes roughly doubled over the first half of the year, from about 105,800 in January to more than 200,000 in June, the ministry noted.

Meanwhile, Commander of the separate Ukrainian Unmanned Systems Forces Robert “Madiar” Brovdi says the numbers are still growing. In the first five days of October, the force’s pilots killed or wounded 2,699 Russian soldiers, 39.7 percent more than in the same period of September.

He tied the rising number to Russia's assaults in Donbas, as the offensives for the fortress-belt cities that have been Ukraine's protection against full region's occupation since 2014, were ongoing.

Why the drone branch matters

The force fields are the cheap, fast weapons that now do most of the killing on the front. Interceptor and strike drones let Ukraine hit troops, logistics, and command posts while keeping its own soldiers farther from the fight.

On October 4, the US pulled its 12 B-1 strategic bombers out of Fairford, UK and returned them to the United States. Reports say the planes returned to Ellsworth Air Force Base in Rapid City, South Dakota. The bombers were pulled out when intelligence reported that an attack by armed drones against Fairford was imminent. […]

Ukrainian forces are advancing east of Sloviansk and Kramatorsk, and even Russian milbloggers now acknowledge it, the Institute for the Study of War (ISW) said on 8 October. The gains may follow months of groundwork like the one that preceded Operation Vivaldi near Lyman, which Ukraine says returned 176 km² to its control. Russian commentators are already doubting that Moscow can reach the two cities.

Russia's years-long push on the Fortress Belt, the chain of cities anchoring Ukraine's defense in Donetsk Oblast, has been stalling since Vivaldi began. Unable to take those cities, Russia keeps hitting them from the air. On 8 October, a Russian bomb killed 30 people on two buses in Kramatorsk.

Across the Siverskyi Donets

Russian milbloggers said Ukrainian forces liberated Ozerne and advanced east of Pyskunivka toward Kryva Luka, ISW reported. They also acknowledged that Ukrainian troops drove Russian forces out of Pyskunivka. Ukrainians are now counterattacking toward Kryva Luka from the west and northwest, from across the river.

ISW called the repeated Russian claims of a river crossing notable, because the Siverskyi Donets is a significant natural obstacle. Kryva Luka is a dominant height just south of the river. From there, Ukraine could launch further counterattacks. Ukrainian forces appear to have pushed Russian troops off both banks in this area, ISW assessed.

The heights Russia wanted

After Vivaldi cleared ground near Lyman in September, Russia shifted its push south toward Mykolaivka and Sloviansk. Russian forces likely see Mykolaivka, just east of Sloviansk, as a primary objective, ISW said. Its heights would favor an offensive on the city. Ukrainian pushes northeast and southeast of the town now deny Russia that terrain.

East of Kramatorsk, milbloggers claimed Ukrainians liberated Malynivka and advanced between Fedorivka Druha and Holubivka. They also reported gains into southern Minkivka and near Fedorivka. The lines remain tangled. Geolocated footage shows Ukrainian forces striking a Russian position in central Tykhonivka after what ISW assesses was a Russian infiltration.

ISW said the counterattacks may point to a broader Ukrainian goal: pushing Russian forces east, away from the Sloviansk–Kramatorsk area and toward the Siverskyi Donets–Donbas Canal.

The Vivaldi playbook

The counterattacks have run for weeks. On 29 September, Ukrainian military observer Kostiantyn Mashovets reported them in the same areas, saying Russia's 3rd Combined Arms Army had failed to make significant gains. ISW assesses that the attacks build on months of shaping meant to wear down Russia's offensive capacity.

Before Vivaldi, Ukrainian forces targeted Russian drone operators, gaining drone superiority before the counteroffensive. They used the same approach ahead of their Oleksandrivka counterattacks in early 2026.

Moscow appears to see the pattern. A Ukrainian military official said on 7 October that Russia is moving drone units and Spetsnaz from quieter sectors to the Sloviansk–Kramatorsk direction. Ukraine also reorganized its command in and around Donetsk Oblast in early September, which may be blunting Russian attacks from the east, ISW said.

"Distant" and "doomed"

One Russian milblogger called an advance toward the Sloviansk–Kramatorsk area a "distant" prospect, ISW reported. A Russian offensive from Siversk toward Sloviansk may be "doomed" to failure or heavy losses unless Russia retakes the forests south of Lyman, he said.

The counterattacks east of the two cities appear to support Vivaldi, ISW assessed. Together with Russia's defeat north of the river, they could disrupt Russia's offensive toward Sloviansk from the east entirely.

If Ukraine holds Kryva Luka and keeps Russia off the Mykolaivka heights, Moscow's pincer on Sloviansk and Kramatorsk loses the ground it was built on.
