Ukrainian Special Operations Forces (SOF) struck the radar station of a Russian S-400 "Triumf" air defense system in occupied Crimea on the night of September 30, according to a statement shared on Telegram via @wartranslated. The operation, which neutralized the system's "eyes," utilized SOF strike UAVs. In a separate operation on September 27, Ukrainian intelligence forces, with local resistance support, eliminated three Russian National Guard personnel, including a lieutenant colonel and commander of the “Avangard” special unit, in the Stavropol region using an improvised explosive device. The S-400 radar station, described as the "eyes" of the air defense system, was targeted by strike UAVs, rendering the entire system combat-incapable without its surveillance and targeting element, according to the statement from @wartranslated. The incident occurred on the night of September 30. In the Stavropol region incident on September 27, a vehicle carrying the lieutenant colonel, his aide, and driver was destroyed by an IED as it passed, killing all three occupants. This operation was conducted by the Defence Intelligence of Ukraine (HUR) with support from local resistance, as reported on X.com by @bayraktar_1love. Another report on X.com by @front_ukrainian confirms that Ukrainian military personnel from the 73rd Marine Special Operations Center, alongside GUR special forces, ambushed enemy vehicles on Russian territory, resulting in the elimination of three Russian military personnel and the destruction of a service vehicle. These developments follow reports from the previous day concerning drone activity. A family of four was killed in a drone strike on their home in the Sumy region overnight, as reported by NOELreports. Additionally, a Ukrainian FPV drone struck a Russian infantryman near a military checkpoint approximately 20 km away in the same region. Earlier on September 29, explosions and fires were reported in the Volgograd region between 2:00 AM and 2:40 AM UTC, attributed to UAV debris. Governor Andrei Bocharov also stated that fragments from a repelled UAV attack caused power outages and fires in the Volgograd region between 4:35 AM and 5:35 AM UTC on September 29.
