According to the Institute for the Study of War, the aim of Ukrainian counter-offensive in and around Crimea is to regain control of the west bank of the Dnipro River.
“Russian supply lines from Crimea directly support Russian forces in mainland Ukraine including those in western Kherson Oblast. Ukraine’s targeting of Russian ground lines of communication and logistic and support assets in Crimea is consistent with the Ukrainian counteroffensive effort that has also targeted bridges over the Dnipro River and Russian logistical support elements in occupied Kherson Oblast. The net effects of this campaign will likely be to disrupt the ability of Russian forces to sustain mechanized forces on the west bank of the Dnipro River and to defend them with air and artillery assets on the east bank from Ukrainian counterattacks,” ISW reports.
