Russian and proxy troops in Ukraine are likely operating in roughly six groups of forces oriented on Kharkiv City and northeastern Kharkiv Oblast; along the Izyum-Slovyansk line; the Siversk-Lysychansk area; Bakhmut; the Avdiivka-Donetsk City area; and Southern Ukraine. The Kharkiv City and Siversk-Lysychansk groups are likely built around cores drawn from the Western and Central Military Districts respectively. The Izyum-Slovyansk axis is increasingly manned by recently formed volunteer battalions that likely have very low combat power. Wagner Group private military company (PMC) soldiers are in the lead around Bakhmut, while forces drawn from the Donetsk People’s Republic (DNR) predominate in the Avdiivka-Donetsk City area. Troops from the Southern Military District (SMD) likely formed the original core of forces in Kherson and Zaporizhzhia Oblasts but have been reinforced with troops of the Eastern Military District, Airborne Forces, and Rosgvardia. None of these groupings is homogeneous—elements of various military districts, proxy forces, volunteer units, and other formations are scattered throughout the theater. These dispositions suggest that Moscow is prioritizing the advance around Bakhmut and, possibly, toward Siversk with its Russian forces while seeking to draw on the enthusiasm of DNR forces to seize ground they have failed to take since 2014 on the Avdiivka axis. The high concentration of volunteer battalions around Izyum and Slovyansk suggests that that area is not a focus of Russian attention and may be vulnerable to Ukrainian counterattacks. The congeries of forces in and around Kherson Oblast may pose significant challenges to Russian command and control, especially if Ukrainian forces press a counteroffensive there.
