US and Ukrainian officials reported on October 12 and 13 that they anticipated the Russian offensive operations around Avdiivka and expressed confidence in Ukrainian defenses. US National Security Council Spokesperson John Kirby reported on October 13 that the new Russian offensive operations near Lyman and Avdiivka “did not come as a surprise.” Kirby stated that the US is confident that Ukrainian forces will repel these Russian attacks. Kirby also reported that Russian forces appear to be using human wave tactics, wherein the Russian military uses masses of poorly trained and equipped Russian soldiers to attempt to advance - the same practice Russian forces used during their failed winter offensive in winter 2023. ISW has additionally observed Russian forces using higher than usual numbers of armored vehicles in ongoing operations. Ukrainian Main Military Intelligence Directorate (GUR) Representative Andriy Yusov similarly reported on October 12 that Ukrainian forces knew about and prepared for the Russian attack near Avdiivka and that Russian forces did not form sufficient reserves to attack along the entire frontline, but only in certain sectors. Several Russian milbloggers claimed that Ukrainian mines are slowing Russian advances near Avdiivka, indicating Ukrainian prior preparations for the attack.

Ongoing Russian offensive operations throughout the Avdiivka, Donetsk Oblast area on October 13 reportedly faced setbacks around the city. Russian sources claimed that Russian forces continued to attack areas north and south of Avdiivka, and geolocated footage published on October 12 and 13 indicates that Russian forces advanced south of Krasnohorivka (5km north of Avdiivka) and southeast of Pervomaiske (11km southwest of Avdiivka). Russian sources also published conflicting reports about previous claims by Russian sources of Russian control of the Avdiivka Coke Plant, and ISW has not observed any evidence to confirm that Russian forces control the plant as of publication. Ukrainian military officials reported that Ukrainian forces continue to repel Russian attacks around Avdiivka.[3] A Russian milblogger noted that Ukrainian forces are using minefields to slow down Russian advances in the Avdiivka direction. A Russian volunteer in the 4th Luhansk People’s Republic (LNR) Brigade (2nd Army Corps, Southern Military District) claimed that worn out barrels are reducing the accuracy of Russian artillery near Avdiivka, a complaint about Russian artillery that ISW has previously observed from Russian sources.The volunteer assessed that Russian forces can ”compress the [Ukrainian] perimeter” by capturing less fortified Ukrainian-held territory near Avdiivka, but expressed concern that Russian generals will misinterpret these limited advances and try to speed up offensive efforts towards Avdiivka. The volunteer noted that such a misinterpretation may lead Russian forces to “beat on concrete” fortifications until these forces run out.

Russian forces likely launched a significant and ongoing offensive effort around Avdiivka, Donetsk Oblast on October 10. ISW observed Russian forces simultaneously attacking northwest, west, and south of Avdiivka using armored assault groups, rotary wing aircraft, and concentrated artillery starting on October 10. Avdiivka City Military Administration Head Vitaliy Barabash indicated that Russian forces are carrying out assaults with air support in 10 to 12 directions around the settlement. Ukrainian military observers framed Russian offensive operations against Avdiivka as a “major attack” and noted that Russian forces used an unusually high number of armored vehicles in combat. Russian forces’ increased use of armored vehicles and aviation – alongside persistent simultaneous ground attacks – indicates that Russian forces are conducting an offensive effort more significant in scope and intent than ISW previously assessed on October 10 and October 11. ISW is revising its assessment that Russian attacks around Avdiivka are local efforts intended solely to fix Ukrainian forces but is not prepared to assess the exact objectives and likely outcome of Russian efforts in the Avdiivka direction at this time.

This report contains two sections: an introductory essay on the regular Russian ground forces; and a fully sourced order of battle (ORBAT) of Russia’s regular ground forces down to the brigade and regiment echelon (with select independent battalions), including the army, ground forces controlled by the the navy, Airborne (VDV) units, and GRU Spetsnaz formations.

Ongoing localized Russian offensive operations near Avdiivka likely demonstrate the ability of Russian forces to learn and apply tactical battlefield lessons in Ukraine. Russian forces launched localized attacks towards Avdiivka after intensive artillery preparation of the battlefield in the early hours of October 10, and geolocated footage from October 10 and 11 confirms that Russian troops advanced southwest of Avdiivka near Sieverne and northwest of Avdiivka near Stepove and Krasnohorivka. The Ukrainian General Staff reported that a grouping of up to three Russian battalions with tank and armored vehicle support intensified offensive operations near Avdiivka. Ukrainian General Staff Spokesperson Andrii Kovavlev clarified that these battalions are part of three motorized rifle brigades of the Southern Military District’s 8th Combined Arms Army.

Russian forces launched localized offensive operations in the Avdiivka area of Donetsk Oblast and southwest of Orikhiv in western Zaporizhia Oblast on October 9, which are likely intended to fix Ukrainian forces away from the Robotyne area. Russian forces intensified offensive operations northwest of Avdiivka near Ocheretyne, Tonenke, and Berdychi and southwest of Avdiivka on the Vodyane-Opytne line. Russian forces also attacked southwest of Orikhiv on the Pyatykhatky-Zherebyanky line, and Russian milbloggers claimed that Russian forces advanced up two kilometers in the area. The Ukrainian General Staff confirmed up to three Russian battalions conducted an attack in the Avdiivka direction, and ISW has observed footage of fighting in the area, but ISW has not observed any confirmation of these claimed Russian advances as of this writing. Russian milbloggers are largely portraying the Avdiivka-area operations as a significant offensive effort aimed at encircling the Ukrainian force grouping in Avdiivka and capturing the city. A successful encirclement of Avdiivka, one of the most heavily fortified areas of the Donetsk Oblast front line, would very likely require more forces than Russia has currently dedicated to the Avdiivka-Donetsk City effort.

Russia advanced legal mechanisms to reform the Leningrad Military District as part of ongoing large-scale military reforms. The Russian federal portal of draft regulatory legal acts published a presidential decree on October 8, prepared by the Russian Ministry of Defense (MoD), which proposes stripping the Northern Fleet (NF) of its status as an “interspecific strategic territorial association.” Russian state media noted that the proposal indicates that the NF will no longer be a separate military-administrative unit equal to a military district, suggesting that the NF and its four constituent regions (The Komi Republic, Arkhangelsk, and Murmansk oblasts, and the Nenets Autonomous Okrug) will be transferred to the reformed Leningrad Military District. Russian military analyst Yuri Fedorov noted that the recreation of the Leningrad Military District suggests that Russia is preparing for possible conflicts with Baltic states and NATO. The Russian military merged the Moscow and Leningrad Military Districts into the Western Military District in 2010. The MoD created the Northern Fleet in 2014 out of territory covered by the Western Military District, and Russian President Vladimir Putin made the NF a military-administrative unit equal to a military district starting January 1, 2021. Russian Defense Minister Sergei Shoigu proposed the recreation of the Moscow and Leningrad Military Districts on the basis of the Western Military District (reversing the 2010 and 2014 changes) in December of 2022, and confirmed that these military districts were under active formation as of August 2023. The MoD’s decision to re-divide the WMD indicates Russia sees the need to restructure its forces facing NATO and likely posture on the Finnish border, although it remains unclear how Russia will be able to mobilize, train, and organize these forces into new military district-level formations.

Ukrainian forces have conducted a campaign of strikes against Russian military infrastructure, headquarters, and logistics routes in Crimea since June 2023 in order to degrade the Russian military’s ability to use Crimea as a staging and rear area for Russian defensive operations in southern Ukraine. Ukrainian strikes on logistics routes are disrupting Russian supplies to Kherson and Zaporizhia Oblast. Strikes on Black Sea Fleet assets are degrading its role as a combined arms headquarters but have not defeated it as a naval force. Ukrainian strikes generate outsized morale shocks among Russian commanders and in the Russian information space. Western provision of long-range missiles to Ukraine would amplify this ongoing, essential, and timely campaign to weaken Russia’s ability to defend southern Ukraine.

The Kremlin is already and will likely continue to exploit the Hamas attacks in Israel to advance several information operations intended to reduce US and Western support and attention to Ukraine. The Kremlin amplified several information operations following Hamas attacks in Israel on October 7, primarily blaming the West for neglecting conflicts in the Middle East in favor of supporting Ukraine and claiming the international community will cease to pay attention to Ukraine by portraying attention to the Middle East or alternatively Ukraine as a zero-sum comparison. Deputy Chairman of the Russian Security Council Dmitry Medvedev claimed the United States and its allies should have been “busy with” working on “Palestinian-Israeli settlement” rather than “interfering” with Russia and providing Ukraine with military aid. The Russian Ministry of Foreign Affairs (MFA) accused the West of blocking efforts by a necessary “quartet” of Russia, the US, the European Union, and the United Nations, leading to an escalation in violence, implicitly blaming the West for the current fighting. Prominent Russian propagandist Sergei Mardan directly stated that Russia will benefit from the escalation as the world “will take its mind off Ukraine for a while and get busy once again putting out the eternal fire in the Middle East.” These Kremlin narratives target Western audiences to drive a wedge in military support for Ukraine, seek to demoralize Ukrainian society by claiming Ukraine will lose international support, and intend to reassure Russian domestic audiences that the international society will ignore Ukraine’s war effort.

Ukrainian forces continued counteroffensive operations near Bakhmut and advanced in western Zaporizhia Oblast on October 6. Ukrainian military sources noted that Ukrainian forces continued successful offensive actions south of Bakhmut near Andriivka (8km southeast of Bakhmut). Geolocated footage posted on October 5 shows that Ukrainian forces have advanced towards a tree line between Robotyne and Verbove, about 6km southeast of Robotyne. Ukrainian Eastern Group of Forces Spokesperson Captain Ilya Yevlash noted that Ukrainian forces are preparing for offensive operations throughout the autumn-winter period. Yevlash emphasized that while supply requirements will increase and rainy and foggy conditions may complicate the use of drones and tactical and army aviation, Ukrainian forces will continue to fight through the winter. Yevlash’s statement supports ISW’s longstanding assessment that weather will not prevent either side from conducting offensive operations throughout the winter of 2023-2024 if they are well-supplied and choose to do so, as they did in the winter of 2022, and that the pace of Ukrainian offensives will be in large part be metered by Western provision of appropriate small-arms and ammunition and non-lethal supplies to Ukraine - not simply winter weather conditions or any specific weapons system.
