Ukraine’s Unmanned Systems Forces say they wiped out three major Russian air-defense systems in just three days, inflicting an estimated $60 million loss on Moscow.

In a statement on Telegram, the branch said operators from the Asgard battalion of the 412th Nemesis Brigade – working with the 12th Special Purpose Center and the special unit “Kabul 9” from the Defense Intelligence (HUR) – struck three high-value targets: a Buk-M1, a Buk-M2, and a Tor-M2 system.

The destroyed systems are among Russia’s most valued battlefield assets:

• Buk-M1 – a mobile mid-range system designed to shoot down aircraft and cruise missiles.
• Buk-M2 – a newer variant with faster radar and longer range, often used to protect key command posts.
• Tor-M2 – a short-range system built to intercept drones, precision weapons, and low-flying missiles.

Together, they form a critical layer of Russia’s air-defense shield. Their loss “significantly weakens” Russia’s ability to defend strategic sites, the Unmanned Systems Forces said.

The strikes come amid a growing wave of long-range Ukrainian drone attacks into Russia and occupied territories.

On the night of Nov. 28, Madyar’s Birds – a separate battalion within Ukraine’s Unmanned Systems Forces – hit and disabled the Saratov oil refinery, one of Russia’s key energy facilities.

Robert “Madyar” Brovdi, the unit’s commander, also warned of escalating operations in the coming weeks, particularly against Russia’s fuel network as he hinted at tit-for-tat moves in response to Russian attacks on Ukraine’s energy grid.

“Gasoline is becoming a scarce liquid in the swamps, and gas and oil are highly flammable. All of this is moving toward complete darkness – a cold, long winter. What comes next will be more intense and louder,” Brovdi said on Friday.

On Nov. 24, the Unmanned Systems Forces struck the Perekop Bromine Plant and a major power substation in occupied Crimea.

Earlier, on Nov. 13, Madyar’s Birds destroyed a base hosting Russia’s “Orion” attack drones in Crimea.

Troops of the 413th “Raid” Regiment also recently hit a new and rare Russian assault vehicle near the border of Dnipropetrovsk and Donetsk regions, disrupting Moscow’s plans to push deeper into Ukrainian territory.
