Yesterday, a geolocation surfaced showing a Ukrainian position on the southeastern-most part of Kostyantynivka being hit by a Russian Rubicon FPV drone. Judging by an analysis of Sentinel-2 satellite imagery, the video was recorded no earlier than October 12, meaning it is new and very much relevant to the current situation in Kostyantynivka. This is not surprising, and the area has remained within my "infiltration zone", which encompasses the area where any soldier from either side might be located at a given time, including the furthest-most Russian infiltration close to the outskirts of Druzhkivka, and the deepest-most Ukrainian positions still present behind Russian lines on the southeastern outskirts of Kostyantynivka. It's likely that some isolated Ukrainian positions are still present even further south on the northern edge of Ivanopillya as well. From a military perspective, these areas are "controlled" by Russia, although they have not achieved full "consolidation". Russia's presence in these areas is overwhelming compared to Ukraine's, so it should not be considered a "grey-zone" in my opinion (hence why I have a separate layer on my map for the "infiltration zone"). The majority of Ukrainian positions of significance within the city limits remain in the northern and northwestern parts of Kostyantynivka, which have remained in a grey-zone on my map for a few months, due to the continued presence of Russian positions intermingled with Ukrainian ones. Russian and Ukrainian forces likely have some form of parity of forces in these outer districts, including some areas with Russian dominance, and others with Ukrainian dominance. Both sides are constantly infiltrating each other's positions, attempting to clear each other out, making it impossible and impracticable to map a defined "frontline" there.
