The context

Ukraine has been systematically targeting Russian S-400 systems to reduce their effectiveness. The S-400 is a advanced surface-to-air missile system capable of engaging aircraft, drones, and ballistic missiles. Destroying such systems is part of a broader Ukrainian strategy to weaken Russia's air defense umbrella and create corridors for aerial operations. The reported strike near Sochi, a city on the Black Sea coast, underscores the expanding reach of Ukrainian drone operations.
