In mid-September, Russia deployed units of its new 25th combined army to the front for the first time. The transfer of these units to Ukraine began at the end of August.
The Ministry of Defense of Great Britain announced this on Twitter, referring to intelligence data. Units of the army's two maneuver components, the 67th Motorized Rifle Division, and the 164th Separate Motorized Rifle Brigade, are fighting west of Severodonetsk and Kremennaya, along the border between Donetsk and Luhansk regions.
