Situation northeast of Dobropillya - information from the ground: Russian infiltrations, using both small assault groups and DRG groups, continue deep into the Ukrainian tactical rear. This has resulted in a deterioration of the situation for Ukraine near Bilozerske, and a slightly less critical situation further east. Active clearing operations by Ukrainian forces continue. Russian infiltrations originate largely from the Novyi Donbas - Nove Shakhove area. The western routes lead towards Bilozerske, while the eastern routes lead towards Zolotyi Kolodyaz and the Novovodyane-Blahodat area. In the Bilozerske area, small Russian infiltration groups have intensified their movements along the railway line and through the treelines north of Hannivka, resulting in an expansion of the grey-zone up to the outskirts of Bilozerske and into Vesele Pole, where they seem to be actually contesting entire areas now, rather than just entering a given position and moving around constantly to avoid being detected. Approximately 15 Russian soldiers were detected within Bilozerske in total a little over a week ago. A portion of them have been holding the southeastern-most high-rise building (48.53124, 37.07267) of the city for over two months since September 2, which I reported on at the time. From the railway line, some small infiltrators move north into the Novovodyane and Blahodat areas, where significant combat occurred a couple of weeks ago, although it seems the Russian presence here has decreased substantially due to repeated Ukrainian clearing operations. In the Zolotyi Kolodyaz area, Russian infiltrators have been moving in small groups from areas east of Vilne, bypassing Vilne and Rubizhne through the indicated routes, and into the western part of Zolotyi Kolodyaz, where they have only sporadically been detected in recent weeks. The main Russian goal does not seem to be holding positions in the town, but rather moving further northwest through the town towards the highway, and then even further towards Blahodat and Vesela Hora, where individual groups continue to be sporadically detected. The reason why I still have most of these infiltration areas as "Ukrainian-controlled", but within the infiltration zone (separate to the grey-zone), is because in most of these routes, Russian soldiers are not stopping to take and hold positions, but rather simply moving through towards their target destination up to 17 km away from the nearest Russian-controlled territory. There is still an overwhelming majority of consolidated Ukrainian positions in these areas, which are used to try disrupt these infiltration operations along the way. Also, in my opinion, a large portion of these small infiltration groups are DRGs, which do not have the task of taking and holding territory, but rather carrying out reconnaissance and sabotage missions behind Ukrainian lines. I have added grey-zones only in areas where Russian forces are actively contesting portions of territory, and not just hopping between positions to try avoid being detected. One of the main reasons why these infiltrators are able to conduct such deep movements - besides the obvious lack of soldiers concentrated along the frontline due to heavy drone usage making this impossible - is how Ukrainian reconnaissance drones are being used. Ukrainian drones primarily survey the actual grey-zone and Russian-controlled territory. This means that there is a certain point where the Russian infiltrators reach an area deep enough where there are substantially less Ukrainian drones in the air searching the land for Russian soldiers, making it much less likely for them to be detected. The number of Russian soldiers in a series of DRG groups, for example, may decrease quite a lot due to heavy casualties as they move through the grey-zone, but once they reach an area a few kilometres from the grey-zone, they could suffer zero additional casualties all the way up to their maximum infiltration depth of around 17 km. #Ukrainemap
