 Russians cannot strengthen Kursan Front, but they are building defence. The Russian army lacks reserves to significantly strengthen its forces on the Kursan Front, but it is rotating forces and building defensive lines there. Natalia Humeiniuk, head of the Joint Press Centre of Operational Command South, said this. Now we do not observe the creation of critical strike groups in our area of responsibility, but we see powerful maneuvers. Russians are trying to replace one force with another. They are trying to transfer additional forces to the Zaporizhia Front. They would like to strengthen the Kursan Front, but so far there are no such critical reserves, although we see the reformation of the groups. Obviously, they are trying to calculate which directions will be the most threatening for them, she added. As Humeiniuk said, the front in Kursan Oblast is not exposed, but some units replace others. More powerful assault units are placed in those directions where there is a threat of the Ukrainians advancing by land. Some of the Russian units are forming defensive lines in Kursan Oblast, where they feel threatened. As Humeiniuk reported, counter-battery measures are taking place on the Nipro Islands, which are considered a grey zone.
