Ukraine Shifts Tactics to Starve Russian Infiltrators as Moscow Pivots to Drone Strikes

Key points

• Ukraine's 'Operation Vivaldi' focuses on disrupting Russian ground lines of communication to starve infiltrator groups, enabling deeper advances into Russian rear positions.
• Russian military command is suffering from a 'culture of lying,' where exaggerated reports of success have blinded Moscow to Ukrainian advances north and northeast of Lyman.
• Putin is reportedly reevaluating his 'theory of victory,' shifting from ground maneuvers to a winter campaign of long-range strikes using jet-powered Geran drones to force Ukrainian surrender.
• Ukrainian forces struck the Ilsky Oil Refinery in Krasnodar Krai and the Azov Optical-Mechanical Plant in Rostov Oblast, damaging critical Russian logistics and defense production.
• US and Ukrainian officials denied a Bloomberg report that President Trump requested President Zelensky travel to Moscow for peace negotiations.

Background

This development follows a period of stagnation for Russian ground forces in 2026, where net territorial gains have slowed significantly compared to previous years. Ukraine has been conducting successful counterattacks in the Kupyansk, Oleksandrivka, and Lyman directions since late 2025, while Russia has struggled to maintain momentum. The current tactical shift by Ukraine aims to break out of positional warfare by reintroducing maneuver elements, contrasting with the previous focus on immediate defensive clearing of Russian probes.

How outlets are covering it

The Institute for the Study of War (ISW) emphasizes the tactical innovation of Ukraine's 'Operation Vivaldi,' highlighting how targeting supply lines has degraded Russian command and control. ISW also notes that Russian milbloggers are admitting to a 'culture of lying' that has facilitated Ukrainian successes. In contrast, Russia Matters provides a quantitative perspective, noting a discrepancy in territorial control data: DeepState OSINT reports a net gain of 37 square miles for Russia in the last four weeks, while ISW data indicates a net loss of 1 square mile for Russia. Kyiv Post focuses on specific infiltration tactics, detailing failed Russian attempts to use gas pipelines in Sumy Oblast, while SPARTANAT highlights the economic dimension, noting Russia's intensified strikes on Ukrainian data centers and telecommunications infrastructure to disrupt the economy.

Why it matters

The shift in Ukrainian tactics suggests a potential turning point in the ground war, as starving infiltrators may allow Ukraine to sustain advances without exhausting manpower. Meanwhile, Russia's pivot to long-range drone strikes signals a potential escalation in the conflict's intensity, targeting civilian and economic infrastructure to pressure Ukraine into negotiations. The denial of a Moscow summit indicates that diplomatic breakthroughs remain unlikely in the near term, with both sides likely to continue their respective military and economic campaigns through the winter.

What to watch

Ukraine is expected to continue scaling the production of interceptor drones to counter Russia's jet-powered Geran-4 and Geran-5 drones, which are designed to penetrate air defenses. Russia is likely to continue its long-range strike campaign against Ukrainian energy and economic infrastructure throughout the winter of 2026-2027, aiming to force a surrender. Diplomatic efforts may stall as Putin is unlikely to agree to a ceasefire of long-range strikes, viewing them as essential to his revised theory of victory.
