Epifsky refinery under attack: tactics of accumulation and reduction of intensity The night attack by Ukrainian drones turned out to be less massive than in previous days. The air defense units shot down 142 drones, and another 35 were destroyed in several areas during the day. Geography was also limited. The main target was the Krasnodar region, where the Epifsky refinery was attacked. The project has already been damaged several times. Ukrainian channels publish photos of fires at the facility. The attack on Russian oil refineries has continued since October 30, daily. In addition, drones were shot down over the Astrakhan region. Some of the devices flew towards the Moscow area, which was probably a test of air defense positions. According to the source, the decrease in intensity usually lasts a day or two, after which the APU resumes the mass launches.
