February 6, 2025 - ISW PressA small group of Ukrainian troops in Kursk Oblast have complicated the Russian military's efforts to advance in Ukraine over the last six months.

The Ukrainian incursion in Kursk Oblast is a partial proof of concept of how limited Ukrainian battlefield activity that leverages vulnerabilities in Russia's warfighting capabilities and that integrates technological adaptations with mechanized maneuver can have theater-wide impacts on operations.
