May 20, 2024 - ISW PressUkrainian sources indicated that Russian forces are concentrating limited, understaffed, and incohesive forces in the Sumy direction, but even such a Russian grouping of forces will be able to achieve the likely desired effect of drawing and fixing Ukrainian forces in the international border area. The deputy commander of a Ukrainian brigade operating in northern Kharkiv Oblast reported on May 20 that Russian forces, including Chechen forces, are accumulating in the Sumy direction but that the limited number of Russian personnel suggests that the Russian objective is to draw and fix Ukrainian forces to the international border area.
