Footage released by Russian sources shows the destruction of what appears to a Ukrainian operated S-125 air defense missile system. It is believed that this strike occurred near Sumy and that the weapon was supporting Ukrainian military operations in the Kursk region of Russia. The S-125 Neva/Pechora has been utilized globally by dozens of countries, and in 2022 a number of these systems were delivered to Ukraine by Poland. From the footage, it's difficult to determine if this is one of the Polish variants of the S-125.
