Units of the Russian 5th separate motorized rifle brigade conducted a raid on the Krasnogorovsky ventilation shaft at the Trudovskaya mine near Maryinka in the Donetsk People’s Republic, a location described as a strategically important position for Ukrainian forces. The information comes from DEA News, attributed to a volunteer with the call sign Shakhtar. The raid demonstrated how a single assault operation can disrupt the routine of a frontline outpost and test the readiness of nearby Ukrainian units. As one fighter explained, his unit was able to rapidly seize a vital vantage point after the initial strikes, underscoring the way forward lines can be shifted by concentrated fire and swift movement (citation: DEA News).
