Ukraine likely neutralized Russia's drone defenses north of Lyman before sending armor into the third phase of its Vivaldi counteroffensive, the Institute for the Study of War (ISW) assessed. An intermediate-range strike campaign against Russian logistics and electronic warfare paved the way, the think tank said.

Drones have made this front so deadly that armor now mostly fights from kilometers back. That is what makes Ukraine's armored push onto fortified positions near Lyman stand out. Russia has already shifted its effort south toward Sloviansk after losing the Lyman pincer.

Armor reached Russian bunkers without drawing drone strikes

To break the strongest Russian fortifications, Ukraine used old Soviet BTR-60 armored personnel carriers rebuilt as remote-controlled explosive vehicles, the 3rd Army Corps says.

Ukrainian forces drove them up to heavy Russian fortifications without coming under Russian drone strikes, ISW noted. The think tank said this indicates Ukraine neutralized or otherwise negated Russia's drone defenses in the area.

Strikes on fuel starved Russia's jammers

Ukraine achieved tactical drone overmatch through extensive shaping operations and an intermediate-range strike campaign, ISW said. Those strikes targeted the Russian drones and electronic warfare (EW) systems that would otherwise have hunted the advancing vehicles.

The 3rd Army Corps reported on 17 September that strikes on Russian logistics in occupied Luhansk Oblast had degraded Russian fuel supplies to the front, ISW wrote that day. The corps said that strained Russia's ability to use drones and EW against Ukrainian drones. EW systems consume a lot of power, and Russian troops run them on diesel generators, ISW explained.

Deputy corps commander Maksym Zhorin credited strict information silence and a "Protective Drone" system of EW assets, according to the same assessment. He said it helped neutralize around 20,000 Russian drones. The corps had earlier described mapping Russian command posts and striking them to sow panic.

Five settlements and 2,000 Russian losses

The corps liberated Nove, Ridkodub, and Katerynivka and restored control over Karpivka and Novomykhailivka, it said on 28 September. The phase added 51 km², bringing the total since the offensive began to 176 km².

Russian losses reached 2,000 personnel, and more than 250 Russians were taken prisoner, according to the corps. Corps commander Andrii Biletskyi said a feint from Shandryholove toward Zelena Dolyna drew Russian reserves away from the real target, Nove.

The first two phases had reportedly cleared more than 125 km² north of Lyman.

A midday explosion in the center of Russian-occupied Luhansk killed Manolis Pilavov, the city's former Russian-installed mayor, Russian state news agency TASS reported on July 3.

Pilavov headed the occupation administration of Luhansk city from December 2014 until stepping down in November 2023. He had been wanted in Ukraine since 2015 on charges including attempting to violently overthrow the constitutional order and violating Ukraine's territorial integrity.

The blast occurred around noon local time, according to TASS. Three people were reportedly injured, one of them in serious condition.

Ukraine has not commented on Pilavov's reported death. Explosions targeting collaborators and occupation officials have become more frequent in recent months.

Pilavov, born in 1964, held several posts in the local Luhansk administration before Russia occupied parts of Ukraine's eastern Luhansk Oblast in 2014.  

He served as a city council member representing the now-banned pro-Russian Party of Regions and later actively supported the local Russian occupation administration.

Ukrainian authorities say Pilavov participated in separatist propaganda events and encouraged support for Moscow's proxy occupation structures shortly after Russian-backed militants took control of parts of Luhansk Oblast in 2014.

Luhansk remains under Russian occupation, with its city center and government institutions controlled by Kremlin-installed proxies.

Ukrainian forces reportedly struck a Russian logistics hub and an oil depot in Russian-occupied Luhansk and a military base in occupied Donetsk on June 30 and July 1, with fires breaking out in the two cities.

"Russian logistics in temporarily occupied Luhansk are burning," head of Ukraine's Center for Countering Disinformation Andrii Kovalenko said.

The drone attack was reported by the local media, publishing what appear to be videos of the burning logistics hub and the sound of drones.

Leonid Pasechnik, head of the Russian occupation authorities in Luhansk Oblast, reported that air defenses shot down 35 of the 40 drones over Luhansk Oblast. Drone wreckage fell on the premises of an oil depot, and a woman was injured, Pasechnik claimed.

Overnight Ukrainian attacks were also reported in occupied Donetsk, with Telegram news channels sharing apparent footage of damaged buildings and fires in the city.

Denis Pushilin, the head of the Russian occupation authorities in Donetsk Oblast, claimed that one person was killed and three were injured in the attack. Ukrainian news channel Supernova+ reported that the attack targeted the headquarters of Russia’s 8th Combined Arms Army.

The Ukrainian military has not commented on the claims, which could not be independently verified.

Ukraine's military regularly strikes military targets in Russian-occupied territories and deep within Russia in an attempt to diminish Moscow's fighting power as it continues its war against Ukraine.

Ukraine's military intelligence (HUR) destroyed three Russian air defense systems using drones in the occupied Zaporizhzhia Oblast on June 14.

"Strike drone masters of the Department of Active Operations of the HUR of the Ukrainian defense ministry discovered and destroyed expensive air defense systems of the Russian invaders in the temporarily occupied territory of the Zaporizhzhia region," HUR reported in a post to Telegram.

A Russian Buk-M3, a Pantsyr S1, and a 9S19 Imbir radar from the S-300V air defense system were destroyed in the Ukrainian drone attack.
