Ukrainian forces conducted counteroffensive operations on at least three sectors of the front on August 15 and reportedly advanced in Luhansk Oblast and western Zaporizhzhia Oblast, the US-based think tank Institute for the Study of War reports.
The Ukrainian General Staff reported that Ukrainian forces continued counteroffensive operations in the Bakhmut, Melitopol (western Zaporizhzhia Oblast), and Berdiansk (western Donetsk-eastern Zaporizhzhia Oblast) directions.
Coordinates published by a Russian milblogger on August 15 indicate that Ukrainian forces have advanced south of Dibrova (7km southwest of Kreminna).
Geolocated footage posted on August 14 indicates that Ukrainian forces advanced into Robotyne, and further Russian and Ukrainian reporting published on August 15 suggests that Ukrainian forces have committed additional counteroffensive brigades to the western Zaporizhzhia oblast area.
Ukrainian Colonel Petro Chernyk stated that the Ukrainian counteroffensive is advancing slowly in southern Ukraine because Ukrainian forces must overcome a three-echeloned Russian defensive line.
Chernyk stated that the Russian line of defense includes a first line of minefields stretching several kilometers wide; a second line with artillery, equipment, and personnel concentrations; and a third line of rear positions meant to preserve resources.
Chernyk noted that Ukrainian counterbattery measures are especially important in order to prevent Russian artillery from targeting Ukrainian mine-clearing equipment.
