Russian high-ranking military officials, including Russian President Vladimir Putin, continue presenting greatly exaggerated claims of Russian frontline advances that do not correspond to battlefield realities in order to present a falsely constructed narrative of pervasive Russian military success. Putin visited the Russian Joint Grouping of Forces (GoF) auxiliary command post on October 16 and met with the Russian General Staff leadership and command staff.[1] Putin claimed that Russian forces seized around 6,500 square kilometers of territory and 310 settlements since the beginning of 2026 and added that Russian forces are “confidently advancing” along the entire frontline. Russian Chief of the General Staff Army General Valery Gerasimov told Putin that Russian forces seized over 1,800 square kilometers of territory and 92 settlements since September 1, 2026. ISW has observed evidence to assess that Russian forces have seized about 100 square kilometers and 69 settlements since January 1, 2026, and suffered a net loss of 122 square kilometers since September 1, 2026. Both Putin and Gerasimov are communicating performance metrics that exaggerate Russian frontline successes. ISW has also observed evidence that Russian forces have lost on average seven kilometers daily thus far in October 2026 — contrary to Putin’s false claim of continued Russian advances.

Gerasimov claimed that the Russian Northern GoF completed the encirclement of Ukrainian forces in northern Kharkiv Oblast and seized 461 square kilometers and 28 settlements but provided no evidence.[2] Russian sources first claimed the encirclement of Ukrainian servicemembers northeast of Kharkiv City on September 3, 2026, and have since continued to repeatedly make baseless claims of tightening the encirclement and seizing new settlements, contrary to all available evidence and refutations from official Ukrainian sources.[3] The Russian Northern GoF Commander Colonel General Yevgeny Nikiforov claimed that “the security strip” along the Russian-Ukrainian border stretches for over 600 kilometers, 465 kilometers (or about 75 percent) of which is under Russian control.[4] ISW has observed evidence to assess that Russian forces control only 205.77 square kilometers of the security strip from the E101 Kyiv City-Hlukhiv highway in the north to the contiguous frontline in the Velykyi Burluk direction (northeast of Kharkiv City). Nikiforov also claimed that Russian forces seized more than 3,000 square kilometers since the establishment of the Putin-proclaimed demilitarized “sanitary zone” in Kharkiv Oblast in March 2024.[5] ISW has observed evidence to assess that Russian forces gained a net of 114.66 square kilometers and seized five settlements in Kharkiv Oblast since January 1, 2026. Nikiforov claimed that Russian forces seized 14 settlements and more than 300 square kilometers of Sumy Oblast during the Summer-Fall 2026 period.[6] ISW has observed evidence to assess that Russian forces seized 99.1 square kilometers in Sumy Oblast since January 1, 2026.

Gerasimov claimed that Russian forces seized Palamarivka (northwest of Kupyansk) and Kovalivka (west of Kupyansk).[7] ISW has only observed evidence of limited Russian infiltration groups operating in Tyshchenkivka (2.2 kilometers northeast of Palamarivka). The nearest assessed Russian advances are within Radkivka (over five kilometers east of Palamarivka and Kovalivka). Gerasimov falsely claimed that Russian forces had entered Velyka Shapkivka (roughly 800 meters north of Palamarivka) exactly five months ago on May 16.[8]

Gerasimov claimed that Russian forces seized around 500 square kilometers and 23 settlements in Donetsk Oblast since September 2026 and Putin claimed that Ukrainian forces currently control 2,748 square kilometers, or just over 10 percent, of Donetsk Oblast.[9] ISW has observed evidence to assess that Russian forces seized three settlements but suffered a net loss of -198.28 square kilometers in Donetsk Oblast since September 1, 2026 and that Ukrainian forces currently control 5,530 square kilometers, or 20.4 percent, of Donetsk Oblast. Gerasimov claimed that Russian forces seized Oleksiievo-Druzhkivka (northwest of Kostyantynivka) after seizing Kostyantynivka in July 2026, entered into southeastern and southwestern Druzhkivka, and reached the outskirts of Kramatorsk.[10] Gerasimov added that elements of the Russian 3rd Combined Arms Army (formerly 2nd Luhansk People’s Republic Army Corps, Southern Military District [SMD]) control 50 percent of Mykolaivka (east of Slovyansk). ISW has observed evidence of Ukrainian forces in western Kostyantynivka, mostly recently on October 10, and has not observed any evidence of Russian forces infiltrating into Oleksiievo-Druzhkivka or consolidating positions within the settlement.[11] ISW has observed evidence that Russian forces are at least 12 kilometers from Druzhkivka and nine kilometers from Kramatorsk when including Russian infiltration efforts that do not constitute doctrinal control of terrain. Gerasimov also credited elements of the Russian 110th Motorized Rifle Brigade, 114th Motorized Rifle Brigade, and 5th Separate Motorized Rifle Brigade (all 51st Combined Arms Army [CAA], formerly 1st Donetsk People’s Republic Army Corps [DNR AC], SMD), 61st Separate Naval Infantry Brigade (Northern Fleet), and 177th Separate Naval Infantry Regiment (Caspian Flotilla) with the claimed seizure of Dobropillya.[12] Gerasimov also claimed that Russian forces seized Pervomaiske and Serhiivka (north and southwest of Dobropillya respectively) and entered Bilozerke (southwest of Pervomaiske). ISW has not observed any evidence to suggest that Russian forces have advanced north of or into Dobropillya beyond limited infiltration efforts and Ukrainian forces have repeatedly refuted Russian claims that Russian forces have consolidated positions in Dobropillya.[13]

Putin claimed that Ukrainian forces currently control only 16.5 percent of Zaporizhia Oblast.[14] ISW has observed evidence to assess that Ukrainian forces currently control 24.6 percent of Zaporizhia Oblast. Gerasimov claimed that Russian forces seized Malokaterynivka (immediately south of Zaporizhzhia City) and are five kilometers from the southern outskirts of Zaporizhzhia City.[15] ISW has observed evidence to assess that Russian forces are at least 20.95 kilometers from Zaporizhzhia City, or 11.6 kilometers when accounting for Russian infiltration efforts. Gerasimov also claimed that the Russian Eastern GoF seized over 180 square kilometers and 10 settlements, including Samiilivka, Holubkove, and Mykilske (all northeast of Orikhiv) in eastern Zaporizhia Oblast since September 2026.[16] ISW has observed evidence to assess that Russian forces seized 104.5 square kilometers and 8 settlements in Zaporizhia Oblast since September 1, 2026 and that Russian forces are at most nine and 13 kilometers from these settlements northeast of Orikhiv when accounting for Russian infiltration efforts. Gerasimov claimed that the Russian Dnepr GoF is fighting in Orikhiv and seized Novopavlivka and Novoandriivka (both northwest of Orikhiv).[17] The Ukrainian 17th Army Corps reported on October 15 that Ukrainian forces control Novoandriivka.[18]

Putin also used the Russian Joint GoF visit to reject the possibility of any Russian territorial concessions as part of potential peace negotiations to end the war in Ukraine. Putin defined the task of Russian forces as establishing the so-called “security zone” in northern Ukraine and ensuring “absolute security” along the Russian-Ukrainian border.[19] Putin explicitly stated that he does not intend to make this zone a subject of potential peace negotiations with Ukraine. The Kremlin has repeatedly refused to make any territorial concessions of its own, while repeatedly demanding that Ukraine cede territory, including areas which Russian forces do not currently control.[20] ISW continues to assess that the Kremlin refuses to make any diplomatic or territorial concessions to bring the war to an end and remains committed to achieving its original war aims through military means.

Russian high-ranking military officials’ exaggerated claims of Russian advances are part of a broader cognitive warfare effort to falsely portray Russian advances as sweeping across the battlefield such that Ukraine and its Western partners should capitulate to Russia’s negotiation demands. Putin, Gerasimov, and other military commanders have heavily exaggerated Russian advances across different sectors of the theater in publicized formats at least once a month since January 2026.[21] The Russian war effort is currently failing to achieve its operational and strategic objectives amid Ukrainian successful counteroffensives during Operation Vivaldi north of Lyman and in the Oleksandrivka direction in 2026, while Russia’s recruitment numbers have decreased.[22] Russian military officials are likely presenting a false picture of Russian sweeping battlefield successes to pressure Ukraine and its Western partners into capitulating to Russia’s demands, which include the complete seizure of Ukraine’s heavily fortified Fortress Belt that Russian forces have been and likely will be unable to capture militarily.

Russia appears to be reconstituting its armored vehicle assets across Russia despite simultaneously engaging in large-scale combat operations in Ukraine, indicating that the Russian military has not fully abandoned efforts to use mechanized vehicles at scale in modern war. The Russian military likely assesses that it can employ mechanized vehicles at scale against adversaries that have not mastered drone warfare, or possibly against Ukraine if Russian forces succeed in eventually breaking out of positional warfare. An open-source intelligence (OSINT) analyst tracking Russian military depots via satellite imagery reported on October 15 that Russian forces are replenishing the armored vehicles and self-propelled howitzer stockpiles across at least five Russian storage bases.[23] The analyst reported that Russian forces are replenishing the stockpile of T-90M tanks, BTR-82A armored personnel carriers, BMP-3M infantry fighting vehicles (IFV), and possibly BREM armored recovery vehicles at the Russian 22nd Central Tank Reserve Base near Buy, Kostroma Oblast (roughly 730 kilometers from the Finnish border). The analyst reported that Russian forces have been replenishing the stock of 2S19 Msta-S howitzers at the Russian 80th Arsenal of the Russian Main Missile and Artillery Directorate (GRAU) near Gagarka, Sverdlovsk Oblast (roughly 1,780 kilometers from the Finnish border) and 2S43 Malva and 2S44 Giatsint-K howitzers at the Russian 374th Mobilized Deployment Support Center (formerly 216th Storage and Repair Base of Military Equipment) near Petrozavodsk, Republic of Karelia (roughly 185 kilometers from the Finnish border) since 2025. The analyst stated that Russian forces are also replenishing the stock of BMP-3Ms and BMD-4M IFVs at the Russian 6018th Central Tank Base and likely refurbished T-72B3M tanks and BMP-2 IFVs at the Russian 349th Central Tank Storage Base near Topchikha, Altai Krai (roughly 3,160 kilometers from the Finnish border).[24] Radio Free Europe/Radio Liberty journalist Mark Krutov reported on October 16 that satellite imagery from 2025 and 2026 confirms Russia’s ongoing efforts to increase the stockpile of armored vehicles.[25] Krutov noted that Russia’s increased reliance on infiltration tactics (which require infantry but not heavy armored vehicles) to facilitate advances in Ukraine has resulted in a decreased use of armored vehicles. Russia’s continued production of armored vehicles and the refurbishment and repair of vehicles have enabled the Russian military to stockpile armored vehicles at these storage sites. These newly observed vehicles likely represent at most partial and very modest reconstitution of Russia’s vehicle fleet. Not all newly observed vehicles are new production, as many are repairs or refurbished vehicles pulled from long-term storage.

The partial reconstitution of Russia’s armored vehicle and self-propelled howitzer stockpiles indicates that the Russian military has not wholesale abandoned the concept of mechanized maneuver despite primarily relying on infiltration tactics in Ukraine over the past year. Russia’s ability to reconstitute conventional assets and deploy some vehicle stockpiles less than 200 km from Russia’s border with NATO despite not reducing its operational tempo in Ukraine is notable. The dislocation of some newly observed vehicles close to Finland also suggests that Russia seeks to establish a long-term force posture against NATO, augment Russia’s combat power in the direction of NATO, and support potential military contingencies against NATO, regardless of the outcome of the war in Ukraine.

ISW continues to assess that the risk of a conventional Russian military land threat against Finland or the Baltic states remains very low, especially as the war in Ukraine continues. The reconstitution of Russia’s armored vehicle stockpiles and deployments of some vehicles closer to NATO does not automatically translate into combat power or a heightened threat level. The extent to which Russia has trained vehicle crews and deployed complementary forces to these bases remains unclear, and available evidence suggests that the bulk of Russia’s active-duty combat personnel currently operate in Ukraine and suffer very high attrition rates. ISW does not assess that the restoration of Russian armored vehicle stockpiles is an indicator of an imminent Russian use of such assets in any kind of ground offensive against a NATO member state. Large-scale mobilization or a decrease in the offensive tempo across the battlefield in Ukraine would likely allow the Russian military to staff vehicle crews, at which point Russia would have partially restored armor capabilities and may pose a higher threat. Russia’s long-term force posturing requires increased vigilance from NATO to be prepared to deter and, if necessary, defend against Russian military actions in the future, including a Russian military that may have conventional mechanized capabilities on a rapid timeline.

The Kremlin continued the seizure of assets belonging to European companies operating in Russia as part of the ongoing efforts to coerce European states into favorable behavior toward Russia. Russian President Vladimir Putin signed a decree on October 16 that places the Russian assets of five European companies, including a French flooring manufacturer Tarkett, Belgian hygiene products manufacturer Ontex, and German packaging producer Menshen, under the “temporary management” of a Russian Center Capital Management Company LLC.[26] Kremlin Spokesperson Dmitry Peskov stated on October 16 that the decree is a continuation of the Kremlin’s effort to impose external management on companies from “unfriendly” countries that withhold Russian assets and expropriate Russian property, emphasizing that these decisions are “reversable.”^[27] An independent Russian investigative publication, The Insider, reported on October 16 that the owner of Center Capital Management Company LLC is likely former Trans-Baikal Krai First Deputy Prime Minister Marat Mirkhaidarov, a veteran of Russia’s war in Ukraine.[28] The likely involvement of Mirkhaidarov in these seizures, along with the involvement of retired Russian Major General Andrei Krayushkin in the September 2026 seizures, indicates that Putin may aim to consolidate seized foreign assets in the hands of Kremlin allies and war veterans.[29] The October 16 decree expands the existing set of foreign assets under “temporary management” of Russian companies, which has grown substantially since September 2026.[30] The Kremlin has previously linked the seizures of European company assets in Russia to European anti-Russian sanctions policies in an apparent effort to coerce European states into reconsidering policies that harm Russia’s ability to wage its war against Ukraine.[31] The Kremlin may have decided to seize assets of European companies operating in Russia as leverage to coerce European states into unfreezing Russian foreign assets.

An unidentified drone violated Moldovan airspace, crashed, and exploded near Scaieni, Donduseni District — approximately 30 kilometers within Moldova. The Moldovan Ministry of Defense (MoD) reported on October 16 that numerous drones of unspecified origin entered Moldovan airspace and that no fewer than four drones violated Moldovan airspace at least five times overnight on October 15 to 16.[32] The Moldovan MoD reported that one drone fell and exploded in a field near Scaieni (approximately 30 kilometers from the Moldovan-Ukrainian border). The Moldovan MoD did not explicitly attribute the drones violating Moldovan airspace to Russia, but framed the violation as related to large-scale Russian strikes against Ukraine. Drones, likely of Russian origin, continue to intensify regular violations of Moldovan airspace as Russia continues to attempt to normalize violations of European airspace. Russia violated Moldovan airspace at least 20 times between February 2022 and July 2026 and at least nine additional violations since August 2026.[33] Most notably, five Russian drones, including Banderol loitering munitions, crashed in Moldova on October 3.^[34]

We do not report in detail on Russian war crimes because these activities are well-covered in Western media and do not directly affect the military operations we are assessing and forecasting. We will continue to evaluate and report on the effects of these criminal activities on the Ukrainian military and the Ukrainian population and specifically on combat in Ukrainian urban areas. We utterly condemn Russian violations of the laws of armed conflict and the Geneva Conventions and crimes against humanity even though we do not describe them in these reports.

Ukrainian Operations in the Russian Federation

Ukrainian forces struck Russian energy infrastructure in the Khanty-Mansi Autonomous Okrug on October 16 – the first reported Ukrainian strike against the region.[35] A Ukrainian drone strike started a fire at Gazprom’s Chernomyrdin Condensate Stabilization Plant near Surgut (roughly 2,340 kilometers from Russia’s international border with Ukraine), according to open-source analysis from Russian opposition source Astra.[36] The plant processes gas condensate, which is used to produce motor and aviation fuel.[37] Khanty-Mansi Autonomous Okrug Governor Ruslan Kukharuk acknowledged that a Ukrainian drone strike against an industrial facility in Surgutsky Raion started a fire.[38]

The Ukrainian General Staff reported that Ukrainian forces struck a Russian Nebo-U radar station near Magry, Krasnodar Krai (roughly 460 kilometers from the frontline) on the night of October 15 to 16.[39]

Satellite imagery collected on October 15 confirms that the Ukrainian strike against the Borisoglebsk Military Airfield in Voronezh Oblast overnight on October 14 to 15 destroyed four Su-34 fighter jets.[40] Ukrainian officials previously reported that the Ukrainian Neptune cruise missile strike against the airfield destroyed four Su-34M fighter jets and damaged two more.[41]

Russian Supporting Effort – Northern Axis (Russian objective: Create defensible buffer zones in Sumy Oblast along the international border)

See topline text for claims of Russian advances in Sumy Oblast.

Russian forces continued offensive operations in northern Sumy Oblast on October 15 and 16 but did not make confirmed advances.[42]

Ukrainian forces continued their intermediate-range strike campaign against Russian military infrastructure in Bryansk Oblast. The Ukrainian General Staff reported that Ukrainian forces struck two Russian radar stations near Ozarenny (roughly 65 kilometers from the international border) and Trubchevsk (roughly 24 kilometers from the international border), and an electronic warfare system near Novozybkov (roughly 33 kilometers from the international border) on October 15 or overnight on October 15 to 16.[43]

Russian Supporting Effort – Kharkiv Oblast (Russian objective: Push Ukrainian forces back from the international border to create a defensible buffer zone with Belgorod Oblast and approach Kharkiv City)

See topline text for claims of Russian advances in Kharkiv Oblast.

Russian forces continued offensive operations in northern Kharkiv Oblast on October 15 and 16 but did not make confirmed advances as Ukrainian forces counterattacked near Starytsya (northeast of Kharkiv City).[44]

The Russian MoD and Russian milbloggers continue to baselessly claim that Russian forces encircled Ukrainian forces in northeastern Kharkiv Oblast. The Russian MoD claimed on October 16 that Russian forces seized Mykolaivka and Varvarivka (both north of Velykyi Burluk).[45] Russian milbloggers claimed that these alleged seizures were the last Ukrainian-held villages in the alleged encirclement, that Russian forces gained control of the O-210825 Budarky-Vovchansk highway that runs along the northern part of the alleged encirclement, and that Russian forces have effectively eliminated the Ukrainian pocket in the area.[46] One milblogger assessed that Russian forces will use their positions in northeastern Kharkiv Oblast to attack Velykyi Burluk. ISW continues to assess that Russian sources are misrepresenting the situation on the ground, as there is no evidence of an encirclement in northeastern Kharkiv Oblast.[47]

Russian Supporting Effort – Oskil River (Russian objective: Cross the Oskil River in Kharkiv Oblast and push westward into eastern Kharkiv Oblast and northern Donetsk Oblast)

See topline text for claims of Russian advances in the Kupyansk direction.

Russian forces continued infiltration missions within Kupyansk. Geolocated footage published on October 15 shows Ukrainian forces striking Russian forces in northwestern and western Kupyansk after what ISW assesses were Russian infiltration missions.[48] A Russian milblogger claimed that Russian forces advanced on the southwestern outskirts of Kupyansk.[49]

Russian forces continued offensive operations southeast of Borova on October 15 and 16 but did not advance.[50]

Russian Main Effort – Capture Ukraine’s Fortress Belt and complete the seizure of Donetsk Oblast

Russian Subordinate Main Effort #1 – Encircle the Fortress Belt from the northwest (Russian objective: Seize Lyman and cross the Siverskyi Donets River to support a wide encirclement of the Fortress Belt – assessed objective of the Russian 25th Combined Arms Army and Western Grouping of Forces elements)

Russian forces recently conducted an infiltration mission southeast of Lyman. Geolocated footage published on October 15 shows Ukrainian forces striking Russian servicemembers in central Yampil after what ISW assesses was a Russian infiltration mission.[51]

Russian Subordinate Main Effort #2 – Advance on the Fortress Belt from the east (Russian objective: Advance on Slovyansk, Kramatorsk, and Druzhkivka from the east – assessed objective of the Russian 3rd Combined Arms Army and Southern Grouping of Forces elements)

See topline text for claims of Russian advances in the Fortress Belt area.

Ukrainian forces maintained positions or advanced east of Slovyansk. Geolocated footage published on October 15 shows Russian forces striking Ukrainian positions west of Kalenyky (east of Slovyansk) — an area in which Russian sources previously claimed Russian forces maintained positions.[52]

Russian Subordinate Main Effort #3 – Advance on the Fortress Belt from the south (Russian objective: Advance on Kostyantynivka and Druzhkivka from the south and southwest, east of the Kazennyi Torets River – assessed objective of the Russian 8th Combined Arms Army and Southern Grouping of Forces elements)

A Russian milblogger claimed that Russian forces fully control Kostyantynivka, but ISW has not observed evidence to assess that Russian forces have seized the city.[53] ISW has observed evidence to assess that Russian forces have only infiltrated into but have not consolidated positions in significant portions of southern and central Kostyantynivka. ISW has not observed evidence of a Russian presence in northern Kostyantynivka.

The milblogger also claimed that Russian forces are fighting near Kindrativka (between Olekiievo-Druzhkivka and Druzhkivka) and striking crossings over the Kryvyi Torets River in the area.[54] ISW has not observed evidence of a Russian presence near or within Kindrativka nor within Oleksiievo-Druzhkivka.

Russian Subordinate Main Effort #4 – Encircle the Fortress Belt from the southwest (Russian objective: Conduct a wide encirclement of the Fortress Belt from near Dobropillya and Pokrovsk west of the Kazennyi Torets River – assessed objective of the Russian 51st Combined Arms Army and Central Grouping of Forces elements)

Russian forces conducted a relatively large number of attacks in the Dobropillya direction on October 15 and 16. The Ukrainian General Staff’s situation report at 0800 October 16, which covers activity in the past 24 hours, reported that Russian forces attacked 60 times in the Pokrovsk (Dobropillya) direction.[55] One Russian milblogger claimed that Russian forces advanced east of Zolotyi Kolodyaz (northeast of Dobropillya), while another milblogger claimed that Ukrainian forces counterattacked near the settlement.[56]

Russian Supporting Effort – Advance into Dnipropetrovsk Oblast (Russian objective: Interdict Ukrainian ground lines of communication that support Ukrainian positions in Donetsk Oblast and envelop Ukrainian positions in southwestern Donetsk Oblast – assessed objective of elements of the Russian Central and Eastern groupings of forces)

Neither Russian nor Ukrainian sources reported ground activity in the Novopavlivka direction on October 16.

A Russian milblogger claimed on October 15 that Russian forces continued offensive operations in the Oleksandrivka direction as Ukrainian forces counterattacked southeast of Oleksandrivka, but ISW has not observed evidence that Russian forces advanced.[57]

Russian Supporting Effort – Southern Axis (Russian objective: Maintain frontline positions, secure rear areas against Ukrainian strikes, and advance within tube artillery range of Zaporizhzhia City – assessed objective of the Russian Eastern and Dnepr grouping of forces)

See topline text for claims of Russian advances in Zaporizhia Oblast.

Russian forces continued offensive operations in the Hulyaipole direction on October 15 and 16 but did not advance.[58]

Ukrainian forces recently advanced in western Zaporizhia Oblast. Russian forces struck a Ukrainian position in southern Stepnohirsk (west of Orikhiv), according to geolocated footage published on October 15, indicating that Ukrainian forces recently advanced in the area.[59]

Russian forces reportedly continue to attack the islands in the Dnipro River Delta. A Ukrainian naval infantry corps spokesperson reported on October 16 that Ukrainian forces recently thwarted a Russian attempt to land two boats on an unspecified island in the Dnipro River Delta.[60] Russian forces unsuccessfully attempted to cross the Dnipro River in an inflatable watercraft and secure positions on the right (west) bank of the river near Prydniprovske (east of Kherson City), according to geolocated footage published on October 12.[61]

Russian Air, Missile, and Drone Campaign (Russian Objective: Target Ukrainian military and civilian infrastructure in the rear and on the frontline)

Note: The Ukrainian military ceased regularly reporting the numbers of Russian missiles fired and the number of missiles intercepted as of August 11.[62]

Russian forces conducted a series of drone strikes against Ukraine overnight on October 15 to 16 and during the day on October 16. The Ukrainian Air Force reported that Russian forces launched 149 Shahed-type (108 of which were jet-powered) and Gerbera-type strike drones and Parodiya-type decoy drones from the directions of Oryol City; occupied Donetsk City; and occupied Hvardiiske, Crimea overnight.[63] The Ukrainian Air Force reported that Ukrainian forces downed 114 drones (77 of which were jet-powered), that 27 drones struck 24 locations, and that drone debris fell on 14 locations. The Ukrainian Air Force reported that Russian forces subsequently launched 315 drones (78 of which were jet-powered) and 15 S-8000 Banderol/Dan-T loitering munitions during the day on October 16 and that Ukrainian forces downed 253 drones (49 of which were jet-powered) and nine S-8000 Banderol/Dan-T loitering munitions.[64]

Russian drone strikes caused large-scale power outages across Ukraine overnight on October 15 to 16 and on October 16. Ukrainian state energy operator Ukrenergo reported that Russian strikes on energy infrastructure caused power outages in Kyiv, Volyn, Odesa, Zaporizhia, Dnipropetrovsk, Kharkiv, Sumy and Chernihiv oblasts.[65] Ukraine’s largest energy company DTEK reported that Russian strikes on energy infrastructure caused emergency power outages in Kyiv Oblast.[66] Volyn Oblast Military Administration Head Roman Romanyuk stated that Russian strikes left 270,000 customers without electricity in the region.[67] Kharkiv City Mayor Ihor Terekhov stated that Russian strikes on an energy facility in Kharkiv Oblast on the morning of October 16 left 280,000 customers without power.[68]

Significant activity in Belarus (Russian efforts to increase its military presence in Belarus and further integrate Belarus into Russian-favorable frameworks)

The Collective Security Treaty Organization (CSTO) concluded the active phase of two exercises in Belarus. The Belarusian MoD reported on October 16 that the CSTO concluded the active phase of its Indestructible Brotherhood 2026 command staff exercise involving CSTO peacekeeping forces and its Barrier-2026 exercise involving nuclear, biological, and chemical defense forces and medical support teams in Belarus.[69] The CSTO began conducting the exercises on October 11 with participation from military contingents from Belarus, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan.[70]
