Russian infiltrators conducted sabotage missions behind Ukrainian positions in the Dobropillia direction, with two Russians spotted and eliminated in Zolotyi Kolodyaz and an ambush on a Ukrainian pickup truck killing all passengers and the ambushers, according to an X post by @Playfra0 during the 59-minute reporting window from 8:45:46 PM to 9:45:36 PM UTC on February 2, 2026. Russian forces have shifted to deep infiltrations with small groups due to general frontline inactivity, achieving occasional success in sabotage, as stated by @Playfra0. Ukrainian soldiers reported Russians dying "on an industrial scale," confirming a 1:15 loss ratio, while Russians face difficulties accumulating forces in the open terrain. Activity remains low in Sofiivka/Shakhove but higher near Novyi Donbas, Bilytske, and Rodynske. Ukrainian forces expressed confidence in holding Shakhove/Sofiivka, with Russians expected to redirect efforts westward toward Dobropillia itself, per the X post published in this period. No specific timing for the Zolotyi Kolodyaz incident or ambush was provided beyond "recently." This follows quiet periods in prior windows with no major Belgorod developments and a Russian drone strike on a vehicle in Raihorodok, Donetsk Oblast, at 48.90336, 37.71890, geolocated earlier on February 2, 2026, by @GeoConfirmed, @UAControlMap, @AndrewPerpetua, and @zarGEOINT.
