Russian forces continued to prioritize holding positions around the Russian border to prevent further Ukrainian advances north of Kharkiv City and will likely continue to do so at the expense of deploying additional reinforcements to other axes of advance. Russian troops focused on maintaining their positions on the Southern Axis and on conducting rocket, missile, and artillery strikes along the frontline.
