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.

Hunting the hunters

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.

Named for four seasons

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.

A new hand at the Third Corps

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.

Biletskyi’s count

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.

Patrol density along Lithuania’s border with Russia’s Kaliningrad exclave has practically doubled since soldiers joined the border guards there in early October. Lithuanian Armed Forces Commander Raimundas Vaikšnoras told LRT this in an interview. He linked the deployment to provocations and to what he described as Russian preparations for a large-scale mobilization.

Kaliningrad is a piece of Russia wedged between Lithuania and Poland on the Baltic Sea. Lithuanian Defense Minister Robertas Kaunas said people would naturally flee a Russian mobilization. Earlier, on 11 August, President of Ukraine Volodymyr Zelenskyy said that Russia planned to mobilize several hundred thousand people by the end of 2026, after its parliamentary vote.

Commander: Russia lacks troops for a breakthrough

Vaikšnoras said Russia is struggling in Ukraine and needs to fill gaps in its capabilities. Moscow would probably like a breakthrough but lacks people, he added. In July, Ukraine’s Foreign Intelligence Service estimated that Russia had signed about as many new military contracts this year as it had lost troops.

He also cited provocations. In Latvia, armed men recently tried to push migrants across the border, he noted, leaving open whether they were bandits or criminals. Belarusian ruler Alyaksandr Lukashenka denies everything, he added. On 6 October, Latvian Interior Minister Jānis Dombrava wrote that the escorts stood on the Belarusian side, were armed, and threatened Latvian soldiers.

Mission extended to mid-November

Lithuania decided to send troops after that Latvian incident. On 7 October, Interior Minister Martynas Katelynas asked Defense Minister Kaunas for troops to help the State Border Guard Service. Kaunas then approved up to 100 soldiers until 16 October, LRT reported.

On 16 October, Kaunas extended the mission to mid-November at Katelynas’s request. The Defense Ministry cited possible flows of people fleeing Kaliningrad and related illegal border crossings. It also said military intelligence sees no significant changes in military activity in Kaliningrad. Katelynas had earlier called the step preventive, BNS noted. He cited public, non-intelligence reports of a call-up planned after Russia’s parliamentary elections and said the threat level at the border had not risen.

Commander doubts Moscow’s intentions

Vaikšnoras said Russia and Belarus may not want open incidents that leave their traces right now. He added that he does not believe in their good intentions. He noted it has been said publicly that Russia’s capability in Kaliningrad is sharply reduced, because most of its forces are committed to Ukraine. Back in June 2025, Poland’s foreign minister said that, from what he knew, Russia had withdrawn a large part of its troops from the exclave.

Instead, hybrid attacks and sabotage that cannot be traced at once will probably continue, Vaikšnoras said. LRT noted the interview took place before a Ukrainian drone crashed in Pasvalys district on Sunday and before an attempted arson at premises used by SpaceX in Vilnius.

Reports that SpaceX temporarily restricted its satellite internet service for Ukraine’s armed forces have generated serious concern in Kyiv and among the country’s allies. SpaceX operates the civilian Starlink system and its lesser-known military-grade counterpart, called Starshield. But many news stories leave an important question unanswered: what does a Starshield “slowdown” mean on the battlefield? […]

• A new Ukrainian list of foreign parts in Russia's anti-jamming antenna is filled with US electronics.
• GUR published a catalog of US digital processors, chips, and other components found in the Kometa.
• These arrays are used to help Shaheds and Iskander-M missiles navigate and suppress jamming.

Over two dozen US processors, chips, and other components have been found in Russia's anti-jamming antenna systems, according to Ukraine's military intelligence.

The Ukrainian agency, GUR, published a list of foreign parts on Monday that it said were discovered in 16-element Kometa modules, one of Russia's more advanced systems that help drones and ballistic missiles suppress electronic warfare and navigate the skies.

US-headquartered firms produced 28 out of 37 foreign components — or just over three-quarters — listed on Monday, per GUR.

Ten American brands and their components were identified in the catalog, posted on GUR's War and Sanctions page. These include digital processors from Intel subsidiary Altera, radio-frequency and precision components from Analog Devices, a memory chip from Micron, and supporting electronics from Texas Instruments.

Another three components are built by Chinese companies, while the other six come from Japanese, Taiwanese, and Swiss manufacturers, GUR also indicated.

In a statement to Business Insider, a Texas Instruments spokesperson said the company "strongly opposes the use of our chips in Russian military equipment."

"Any shipments of TI chips into Russia are illicit and unauthorized. We devote significant time and resources to developing, implementing, and refining policies and procedures to combat illicit diversion and keep chips out of the hands of bad actors," they added.

Intel, Analog Devices, and Micron did not immediately respond to requests for comment sent outside regular business hours by Business Insider.

The new list from GUR, which regularly publishes information on foreign parts in Russian equipment, comes as the electronic warfare race grows more vital to Ukraine's air defense.

Kyiv's forces try to stop Russian drone and missile attacks with a mix of jamming tools and interceptors, but the latter are facing difficulty as Moscow has begun mass-launching faster, jet-powered drones — the slowest of which can fly at about 185 mph.

Kometa antenna panels are among the most common anti-jamming tools on Russian long-range weapons, such as Shahed drones, Iskander-M ballistic missiles, and glide bombs.

Each antenna receives satellite signals and helps to counter jamming or spoofing.

The 16-element Kometa, which essentially has an array of 16 antennas, is one of Russia's newer versions of the system in mass production. Two years ago, Moscow was regularly using eight-element Kometas on its Shaheds instead.
