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.
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.
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.
Drones struck the seized Ukrtelecom building in occupied Luhansk overnight on 21 October, hitting the mobile operator Russia’s occupation authorities run there under the name “Lugacom,” Russian Telegram channel Astra and Ukrainian monitoring channels reported. The strike came a night after drones hit “Ugletelecom,” the occupation’s telecom operator in Donetsk, which reportedly runs on equipment seized from Ukrainian companies. Footage posted by Ukrainian monitors shows heavy fire damage inside the Luhansk building. Ukraine has not officially commented.
Ukraine has spent months hitting the supply lines, depots, and infrastructure that sustain Russia’s occupation of southern and eastern Ukraine, with mid-range drones striking trucks, trains, and communications towers well behind the front. This spring the commander of Ukraine’s Unmanned Systems Forces, Robert “Madyar” Brovdi, promised Russian troops in occupied territory a “stone age.” This time the targets were the networks the occupation runs on.
Residents reported explosions in Luhansk overnight, and the former Ukrtelecom building was attacked by a drone, Astra reported, citing its readers. The occupation runs its mobile operator, “Lugacom,” from the seized building, and built its network on equipment taken from Ukraine’s Kyivstar, according to dev.ua. The building also houses an occupation-run telecom services center. Luhansk is situated in the easternmost Ukrainian region and has been occupied since 2014.
Ukrainian monitoring channel Exilenova+ said Ukraine’s Defense Forces struck the building, which also hosts an information technology and technical support center. A video it posted shows extensive burning inside. Petro Andriushchenko, head of the Center for the Study of Occupation, said the drones hit a data center in the building.
Occupation officials had not commented, according to NV. In September, drones hit a hardware store in Luhansk, sparking a large fire. Earlier this month, fires broke out at a Russian supply base in Khrustalnyi, also in occupied Luhansk Oblast.
The night before, drones struck “Ugletelecom,” one of the key communications operators in occupied Donetsk Oblast, Exilenova+ reported. It operates from an office building at 60 Postysheva Street, where Ukraine’s state holding company Donbasugleobespechenie was registered before the occupation, according to RBC-Ukraine. Astra found about 27 organizations registered at the address, including internet provider Fticom, and damage on four floors.
Ugletelecom runs on equipment seized from Ukrainian companies, Donetsk-focused outlet Kochegarka reported, citing local sources. The occupation also moved local businesses that had used Ukrtelecom over to it, according to dev.ua. Residents had reported powerful explosions in the city.
In occupied Donetsk Oblast, drones attacked the 330 kV Pivdenna substation in Chystiakove, and locals reported outages, Telegram channel DroneBomber said, calling the report preliminary. Occupied Donetsk went into a blackout on the evening of 20 October after strikes on its power supply, Andriushchenko said. He also reported air defense activity and hits in the Mariupol area.
In occupied Crimea, residents of Krasnoperekopsk reported explosions and hits near the railway station, then partial power cuts, monitoring channel Crimean Wind said. In occupied Melitopol, drones tried to attack the city’s power facilities at around 03:30 but missed, Russian senator Dmitry Rogozin claimed.
French mapper Clément Molin counted 770 confirmed Ukrainian drone strikes on Russian trucks in the logistics zone 10 km behind the front line in September, up from 630 in August.
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.
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.
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.
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.
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.
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.
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.
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.
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.
