Ukraine published videos showing FPV drones destroying Russian air defense systems during the 30-minute reporting window from 1:45:38 AM to 2:15:39 AM UTC on February 27, 2026, according to a post by @joni_askola. The footage highlights vulnerabilities in Russian defenses amid ongoing frontline operations. Russia entered the war with a massive arsenal of air defense systems, but sustained Ukrainian drone strikes have depleted stocks, as noted by @joni_askola in the same post. Ukrainian forces continue to target these systems, demonstrating areas where Russian protections have failed. These publications follow prior reports of Ukrainian drone operations eliminating approximately 8,000 Russian personnel from February 1-26, as detailed by @414magyarbirds, and the destruction of a Russian position in Varvarivka, Zaporizhzhia Oblast, by the 225th Separate Assault Brigade, confirmed by @GeoConfirmed and others.
