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.
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.
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.
Ukraine's drone pilots are killing and wounding far more Russian infantry than they did a month ago. Ukraine's Unmanned Systems Forces confirmed that their pilots took out 2,699 Russian infantry from 1 to 5 October, 39.7% more than in the first five days of September, Commander Robert "Madiar" Brovdi wrote on Telegram on 6 October.
The Unmanned Systems Forces, the branch of Ukraine's military that fights with drones, count only losses verified by their own pilots in the military's Delta system, so the full picture of Russian losses is larger, Brovdi stressed. Compared with the first five days of August, the rise is 76.5%, from 1,529 losses, which he ties to denser and more frequent Russian assaults.
The sharpest growth occurred in the area of the 1st Azov Corps of Ukraine's National Guard on the Dobropillia-Pokrovsk axis in Donetsk Oblast, as fighting for fortress-belt cities continues. Drone pilots recorded 1,268 Russian losses there, 43% more than the 884 of early September and 91% more than the 664 of early August.
"Russia's hidden mobilization is in action. This is the beginning," Brovdi said ironically.
Russia doubles its monthly recruitment pace
Russian recruitment, mobilization, and contracts run at about 70,000 people a month, twice the 35,000 monthly average from January to August 2026, Brovdi noted on 16 September, when he forecast 12,500 losses for his pilots in September.
He expected the toll to keep climbing. Bigger records still lie ahead because of Russia's unannounced mobilization, Brovdi added on 24 September.
Drone pilots outpaced August by a quarter
September was completed above that forecast. The pilots logged 13,358 Russians killed or wounded, 25.35% more than the 11,010 of August, an average of 445 a day against 355, Brovdi reported. By his count, that equals the full assault infantry of one battalion every day, and his pilots hit a Russian target every 42 seconds.
Two sets of axes took the heaviest toll. In the first 24 days of September, the Dobropillia and Pokrovsk axes accounted for 4,018 losses, and the Oleksandrivka and Huliaipole axes for 3,021, according to Brovdi. The first of those groups covers the same Dobropillia-Pokrovsk axis where the Azov corps zone recorded the sharpest October rise.
