The number includes 1,830 casualties that Russian forces suffered over the past day.

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.
