Russian Offensive Campaign Assessment, September 9, 2023

September 9, 2023 - ISW Press

Ukrainian forces made confirmed advances in the Donetsk-Zaporizhia Oblast border area and in western Zaporizhia Oblast and made claimed advances south of Bakhmut on September 9. Geolocated footage published on September 9 shows that Ukrainian forces advanced northwest of Novomayorske (18km southeast of Velyka Novosilka) along the Donetsk-Zaporizhia Oblast border, where Russian sources claim fighting has intensified in recent days. Additional geolocated footage published on September 9 shows that Ukrainian forces also advanced northeast and east of Novoprokopivka (13km south of Orikhiv) and west of Verbove (20km southeast of Orikhiv) in western Zaporizhia Oblast. The Ukrainian General Staff reported that Ukrainian forces achieved unspecified successes south of Robotyne (10km south of Orikhiv). A Kremlin-affiliated Russian milblogger claimed that Ukrainian forces forced Russian forces to withdraw from Andriivka (9km southwest of Bakhmut), and another prominent milblogger claimed that Andriivka is now a contested “gray zone.” Ukrainian officials reported that Ukrainian forces also achieved unspecified success south of Klishchiivka.

Russian forces have reportedly made notable changes to their command and control (C2) in Ukraine to protect command infrastructure and improve information sharing, although Russian force deployments are likely still exacerbating issues with horizontal integration. Center for Security and Emerging Technology (CSET) Deputy Director of Analysis Magarita Konaev and CSET Fellow Owen Daniels stated on September 6 that Russian forces moved headquarters out of range of most Ukrainian strike systems and have placed forward command posts further underground and behind heavily defended positions. It is unclear if Russian forces have employed this more protected command infrastructure throughout Ukraine and to what degree these defensive efforts have impeded Ukraine’s ongoing interdiction campaign. Konaev and Daniels stated that Russian forces have improved communications between command posts and units at the front by laying field cables and using safer radio communications. The Royal United Services Insitute (RUSI) stated on September 4 that Russian forces are also trying to improve signals through the wider use of application-based C2 services that require less training. Konaev and Daniels noted that signals at the battalion level downward are still often unencrypted and that Russian personnel still frequently communicate sensitive information through unsecure channels.

Ukrainian forces continued offensive operations near Bakhmut and in western Zaporizhia Oblast on September 7 and made further gains on both sectors of the front. Geolocated footage published on September 7 indicates that Ukrainian forces have made further advances northwest of Verbove (18km southwest of Orikhiv) in western Zaporizhia Oblast. A prominent Russian milblogger claimed that Ukrainian forces made further advances in the area and other milbloggers claimed that Ukrainian forces temporarily advanced to the northwestern outskirts of Verbove on September 6, likely indicating further recent Ukrainian advances northwest of the settlement. Satellite imagery collected on September 6 shows burning foliage in a tree line roughly a kilometer northwest of Verbove, suggesting that Russian forces are firing on advancing Ukrainian forces in the area. Geolocated footage published on September 7 indicates that Ukrainian forces have made marginal gains northwest of Klishchiivka (7km southwest of Bakhmut). The Ukrainian General Staff reported that Ukrainian forces achieved unspecified successes south of Bakhmut and near Robotyne (10km south of Orikhiv) and Verbove in western Zaporizhia Oblast.

Ukrainian forces continued counteroffensive operations in the Bakhmut and western Zaporizhia Oblast directions and have made gains in western Zaporizhia Oblast as of September 6. Geolocated footage shows that Ukrainian forces have advanced along the trench line west of Verbove (about 20km southeast of Orikhiv), and the Ukrainian General Staff stated that Ukrainian forces achieved unspecified successes in the Robotyne—Novoprokopivka direction south of Orikhiv. The Ukrainian General Staff additionally reported that Ukrainian forces are continuing successful offensive operations south of Bakhmut.

Russian Offensive Campaign Assessment, September 4, 2023

September 4, 2023 - ISW Press

Ukrainian light infantry has advanced to positions beyond anti-tank ditches and dragon’s teeth anti-tank obstacles that comprise the current Russian defensive layer ahead of the Ukrainian advance in western Zaporizhia Oblast, and Ukrainian forces likely intend to hold those positions. ISW is not prepared to assess that Ukrainian forces have breached this Russian defensive layer in the absence of observed Ukrainian heavy equipment in these areas. Geolocated footage published on September 4 indicates that Ukrainian forces advanced to tree-line positions that are east of the Russian anti-tank ditches and dragon’s teeth obstacles that are a part of a tri-layered defense immediately west of Verbove (18km southeast of Orikhiv). Geolocated footage published on September 4 indicates that Ukrainian light infantry has also advanced further into a series of prepared Russian defensive positions along the road that runs northwest into Verbove. Other geolocated footage published on September 4 indicates that Ukrainian forces have advanced up to Russian defensive positions between Robotyne (10km south of Orikhiv) and Novoprokopivka (13km south of Orikhiv). Ukrainian forces are widening the breach they have already made in one Russian defensive layer and are reportedly maneuvering more equipment and personnel into tactical rear areas of this layer. Ukrainian forces appear to be making gains in the immediate vicinity of the not-yet-breached Russian defensive layer that runs northwest of Verbove to north of Solodka Balka (20km south of Orikhiv) with infantry assaults and heavy artillery fire on Russian positions further into and south of this layer. The deployment of Ukrainian heavy equipment and more substantial forces to these areas than ISW has so far observed would indicate both a breach of this Russian defensive layer and an effort to widen that breach.

Ukrainian military officers offered notably frank and direct commentary about the prospects of further Ukrainian advances in western Zaporizhia Oblast and indicated that the series of prepared Russian defensive positions immediately ahead and further south of the Ukrainian advance may be less challenging to Ukrainian forces. Ukrainian Tavriisk Group of Forces Commander Brigadier General Oleksandr Tarnavskyi, who commands the Ukrainian grouping in southern Ukraine, discussed Ukraine’s counteroffensive in an interview with The Guardian on September 2. Tarnavskyi stated that Ukrainian forces have decisively breached Russian forces’ “first line of defense” and that he expects faster Ukrainian gains as Ukrainian forces press on a weaker “second line” of defense. Ukrainian forces have advanced up to the next series of prepared Russian defensive positions in certain areas in the Robotyne area in western Zaporizhia Oblast, although many Russian sources assert that these positions are the first, not the second, defensive layer in a multi-echeloned Russian defense in southern Ukraine. Ukrainian officials and Russian milbloggers are using different terminology to describe the same positions. Russian sources characterize the first series of positions that Ukrainian forces have previously breached as a forward line without giving it an ordinal number, and the series Ukrainian forces are currently approaching as the first main line of defenses — while Ukrainian forces characterize these positions as Russia’s second line of defenses.

Ukrainian forces continued counteroffensive operations in western Zaporizhia Oblast and reportedly advanced on September 2. The Ukrainian General Staff reported that Ukrainian forces conducted offensive operations in the Melitopol (western Zaporizhia Oblast) direction. Russian milbloggers who have recently maintained that Russian forces hold positions in the southern part of Robotyne claimed that Russian forces withdrew from the southern outskirts of the settlement to unspecified positions further south. Ukrainian Deputy Defense Minister Hanna Malyar stated on September 1 that Ukrainian forces have overcome the Russian “first line of defense” in some areas of the Zaporizhia direction, but that the situation remains difficult due to additional Russian concrete fortifications and dense minefields.

Ukrainian Main Military Intelligence (GUR) Head Kyrylo Budanov reported that the Russian military deployed elements of a newly created “reserve army” (the 25th CAA) to enable units currently on the frontline in Luhansk Oblast to laterally redeploy to defend against the Ukrainian counteroffensive in southern Ukraine. Budanov stated on August 31 that the Russian military deployed elements of the newly formed 25th Combined Arms Army (reportedly formed under the Eastern Military District) to replace elements of the 41st Combined Arms Army (Central Military District) in the Kupyansk direction, and that these elements of the 41st Combined Arms Army (CAA) began a “slow” redeployment to an unspecified area in southern Ukraine. Elements of the 41st CAA’s 35th Separate Guards Motorized Rifle Brigade and 90th Tank Division participated in the failed Russian winter 2023 offensive operation in Luhansk Oblast and have continued limited offensive activity along the Svatove-Kreminna line through now. These units are likely degraded and have been operating without brigade and regiment level rotations like many frontline Russian units throughout the theater. ISW previously assessed that a lack of operational reserves would force the Russian command to conduct further lateral redeployments and make tough decisions about what sectors of the front to prioritize.The Russian military command appears to have deployed elements of the newly formed and likely low quality or understrength 25th CAA to Luhansk Oblast to free up the relatively more effective 41st CAA elements for southern Ukraine. Budanov added that elements of the 25th CAA are already participating in hostilities in Luhansk Oblast.

Ukrainian forces continued counteroffensive operations near Bakhmut in Donetsk Oblast and in western Zaporizhia Oblast on August 31 and reportedly advanced in both sectors of the front. The Ukrainian General Staff and Ukrainian Deputy Defense Minister Hanna Malyar reported that Ukrainian forces continued offensive operations in the Bakhmut and Melitopol (western Zaporizhia Oblast) directions and achieved unspecified success in the direction of Novodanylivka-Novoprokopivka (5km to 13km south of Orikhiv) in western Zaporizhia Oblast. Malyar also stated that Ukrainian forces achieved unspecified success in the Bakhmut direction. Ukrainian Chief of the Main Directorate of Missile Forces and Artillery and Unmanned Systems of the General Staff Brigadier General Serhiy Baranov stated that Ukrainian forces have reached parity in counterbattery capabilities with Russian forces. Baranov stated that NATO-provided artillery systems with ranges of 30km to 40km allow Ukrainian forces to destroy Russian artillery systems and force Russian forces to move their artillery further from the frontline. Ukrainian officials previously made statements in late July indicating that Ukraine’s interdiction campaign is successfully degrading Russian counterbattery capabilities. Russian sources have repeatedly expressed concerns since mid-July over the lack of Russian counterbattery artillery capabilities, particularly in southern Ukraine.

Ukrainian forces reportedly destroyed four Russian Il-76 planes during a drone strike on a Russian airfield in Pskov Oblast on the night of August 29 to 30. Ukrainian Main Military Intelligence Directorate (GUR) Representative Andriy Yusov stated that the drone strike destroyed four Russian Il-76 planes and possibly damaged two other planes at the Pskov airfield but did not comment on the nature of the strike or claim responsibility for it. Geolocated footage and Russian sources confirmed the strike and the destruction of at least two Russian Il-76 planes. Russian milbloggers claimed that over 21 Ukrainian drones struck the Pskov airfield. Russian sources, including the Russian Ministry of Defense (MoD), claimed that Russian air defenses and electronic warfare (EW) systems also downed Ukrainian drones over Oryol, Tula, Voronezh, Ryazan, Kaluga, Bryansk, and Moscow oblasts. Moscow Mayor Sergey Sobyanin stated that Russian air defenses repelled a massive Ukrainian drone strike on the Central Federal Okrug (a large administrative area including Moscow but not Pskov) and that at least one of the drones was headed toward Moscow, possibly suggesting that Russian authorities may have initially believed that Ukrainian forces intended to strike Moscow or the region around it. Russian forces may have focused their air defenses on covering Moscow and somehow missed the unusually large number of Ukrainian drones that reportedly struck the Pskov airfield. The Ukrainian drones that Russian air defenses downed over the six other oblasts were likely en route to Moscow or Pskov Oblast and likely were not part of a Ukrainian effort to strike targets in the other oblasts.
