 Russia sends reserve army to southern Ukraine. Russia's military has deployed a reserve army to allow its units from the Lohansk Oblast to relocate to defend the south from an advancing Ukrainian counter-offensive. US-based Institute for the Study of War reported this. Kirill Obudnov, the head of Ukraine's main military intelligence directorate, said that the Russian military has deployed units of the newly created 25th Combined Arms Army to allow units currently on the front line in Lohansk Oblast to move sideways to defend against a Ukrainian counter-offensive in southern Ukraine. The Institute for the Study of War believes that the 25th Combined Arms Army is unlikely to be combat-ready given its hasty deployment. In addition, Institute for the Study of War reported that the invaders were disappointed with Russian counter-battery fire near Eurozane and along the Novo-Mayorsk-Novo-Denets-Kermansk frontline. In addition, Russian troops defending the area are in poor physical condition and under psychological stress. Also, according to Institute for the Study of War, Ukrainian forces continued their offensive near Bakhmut and in western Zaporizhiy Oblast and made some progress on September 1. Geolocation footage shows that Ukrainian forces have made minor advances northwest of Klishchivka.
