Ukrainian forces resumed offensive operations in at least three areas within the Ukrainian salient in Kursk Oblast and made tactical advances on January 5. Russian sources claimed that Ukrainian forces conducted multiple roughly company-sized mechanized assaults in the Berdin-Novosotnitsky direction (northeast of Sudzha) in three waves of attack using roughly a battalion's worth of armored vehicles. Russian sources claimed that Ukrainian forces also intensified offensive operations in the direction of Leonidovo (southeast of Korenevo) and conducted a reinforced platoon-sized mechanized assault near Pushkarnoye (east of Sudzha). Geolocated footage published on January 5 indicates that Ukrainian forces advanced in fields southwest and south of Berdin and entered the southern part of the settlement. Russian milbloggers published updated maps of the Kursk area of operations that indicate that Ukrainian forces also occupy Cherkasskoye Porechnoye, Martynovka, and Mikhaylovka (all northeast of Sudzha and southwest of Berdin) as of January 5 and reported that Ukrainian forces recently entered Novosotnitsky (just east of Berdin); and advanced in fields west of Yamskaya Step (immediately northwest of Berdin) and west of Novaya Sorochina (north of Sudzha and northwest of Berdin). Russian milbloggers reported that Ukrainian forces also conducted offensive operations near Nikolskiy and Alexandriya (east and southeast of Leonidovo, respectively) and north of Russkaya Konopelka (east of Sudzha) towards Pushkarnoye in small infantry groups but did not provide details about the extent of any possible Ukrainian advances in these areas. Russian milbloggers largely expressed concern that the renewed Ukrainian effort in Kursk Oblast may be a diversionary effort and claimed that it is too early to determine whether these operations in Kursk could be part of a future main effort.
Russian forces also advanced southeast of Sudzha and counterattacked against intensified Ukrainian attacks southeast of Korenevo and north of Sudzha on January 5. Geolocated footage published on January 5 shows that Russian forces advanced in western and southern Makhnovka (just southeast of Sudzha). Russian milbloggers claimed that unspecified Russian airborne (VDV) elements pushed Ukrainian forces from Makhnovka and Dmitryukov (immediately northeast of Makhnovka). A Kremlin-affiliated milblogger claimed that Russian forces may have advanced into Makhnovka "some time ago, however. Ukrainian President Volodymyr Zelensky stated on January 4 that Russian and North Korean forces lost up to a battalion of infantry near Makhnovka on January 3 and 4. Another Russian milblogger claimed that Russian forces also advanced southeast of Makhnovka and along a road into southeastern Kurilovka (immediately southwest of Makhnovka). ISW has not observed visual confirmation of these claims, however. Russian milbloggers claimed that Russian forces also advanced during counterattacks against Ukrainian assaults east of Leonidovo towards Nikolskiy and in the direction of Malaya Loknya (northeast of Sudzha) on January 5. Another Russian milblogger claimed that a Russian mechanized column unsuccessfully attempted to advance towards Malaya Loknya, however. The milblogger complained that Ukrainian forces destroy most Russian mechanized columns in Kursk Oblast. Elements of the Russian 155th Naval Infantry Brigade (Pacific Fleet, Eastern Military District [EMD]), Chechen Akhmat "Aida" Spetsnaz group, former Wagner Group personnel, and unspecified BARS (Russian Combat Army Reserve) units reportedly defended against the Ukrainian effort in Kursk Oblast.
