It’s Time for the West to Embrace Ukraine’s Way of War, Not Doubt It

Ukrainian forces have adapted. Ukraine’s military decision-making is sound. Now is not the time for Western doubt but for the West to embrace Ukraine’s way of war and commit to sustaining Ukraine’s initiative on the battlefield.

Russian Offensive Campaign Assessment, September 23, 2023

ISW is now prepared to assess that Ukrainian forces have broken through Russian field fortifications west of Verbove in western Zaporizhia Oblast. These fortifications are not the final defensive line in Russia’s defense in depth in western Zaporizhia Oblast, but rather a specific series of the best-prepared field fortifications arrayed as part of a near-contiguous belt of an anti-vehicle ditch, dragon's teeth, and fighting positions about 1.7 - 3.5 km west of Verbove.

Ukrainian Tavriisk Group of Forces Commander Brigadier General Oleksandr Tarnavskyi stated in an interview with CNN published on September 23 that Ukrainian forces achieved a “breakthrough” on the left flank near Verbove and that Ukrainian forces continue advancing. Combat footage posted on September 22 shows a destroyed Ukrainian Mine-Resistant Ambush Protected (MRAP) and BMP-2 operating slightly beyond Russia’s fighting positions trench line near Verbove, indicating continued Ukrainian progress in deploying more heavy equipment beyond Russia’s triune belt of the anti-vehicle ditch, dragon’s teeth, and fighting positions. Commercially available satellite imagery indicates that Ukrainian forces have brought heavy equipment closer to Verbove over the past 96 hours in a manner consistent with Tarnavskyi’s statement. The Wall Street Journal reported on September 21 that Ukrainian forces achieved a “limited breakthrough” west of Verbove citing an unnamed Ukrainian Air Assault Forces officer.

Ukrainian armored vehicles are operating beyond the final line of the Russian defensive layer that Ukrainian forces in western Zaporizhia Oblast are currently penetrating, although ISW is not yet prepared to assess that Ukrainian forces have broken fully through this Russian defensive layer. Geolocated footage posted on September 21 indicates that Ukrainian armored vehicles advanced south of the Russian anti-tank ditches and dragon’s teeth obstacles that are part of a tri-layered defense and engaged in limited combat immediately west of Verbove (18km southeast of Orikhiv). It is unclear if Ukrainian forces retain these positions, however. This is the first observed instance of Ukrainian forces operating armored vehicles beyond the Russian tri-layer defense. The presence of Ukrainian armored vehicles beyond the final line of the current Russian defensive layer indicates that the Ukrainians have secured their breach of the first two lines of this layer sufficiently to operate vehicles through the breach. Ukrainian forces have likely suppressed Russian artillery and other anti-tank systems in the area enough to bring their vehicles forward. The Ukrainian ability to bring armored vehicles to and through the most formidable Russian defenses intended to stop them and to operate these vehicles near prepared Russian defensive positions are important signs of progress in the Ukrainian counteroffensive. Additional geolocated footage published on September 20 and 21 indicates that Ukrainian forces also advanced west and southwest of Verbove.

Russian Offensive Campaign Assessment, September 19, 2023

The Russian government quickly signaled on September 19 that Russian peacekeeping forces would not intervene in Azerbaijan’s military operation into Nagorno-Karabakh, despite Russia’s previous security ties to Armenia. The Azerbaijani Ministry of Defense (MoD) announced that Azerbaijani forces began a military operation into Nagorno-Karabakh on September 19. Kremlin Spokesperson Dmitry Peskov claimed that the Russian military is in contact with Armenian and Azerbaijani officials “at the highest level.” Russian Foreign Ministry Spokesperson Maria Zakharova issued a general statement calling on “all sides” to stop the bloodshed, claimed that the Russian peacekeeping contingent in Nagorno-Karabakh continues to fulfil its assigned tasks, and cited the trilateral Russian-Armenian-Azerbaijani agreements signed in 2020 and 2022 as a path toward peace. Russian State Duma Defense Committee Chairman Andrei Kartapolov stated that the Russian peacekeeping contingent does not have the right to use weapons unless directly threatened. A Kremlin-affiliated milblogger claimed that the Russian peacekeeping contingent lacks any protocols on the use of force or rules of engagement in Nagorno-Karabakh, and instead operates on the basis of the November 2020 Nagorno-Karabakh peace agreement.
