Sukharevskyi will replace Major General Dmytro Deliatytskyi in the job, sources confirmed independently to Ukrainska Pravda and Interfax-Ukraine.

The number includes 1,510 casualties that Russian forces suffered over the past day.

The highest number of casualties Ukrainian drones inflicted on the Russian military was recorded in March, with almost 34,000 soldiers killed or irrecoverably wounded.

Key developments on Oct. 26:

• Ukrainian forces carry out 2 aerial evacuations of wounded soldiers, video shows
• Death toll from Russian attack on park in Kharkiv Oblast on Oct. 19 rises to 6 after child dies in hospital
• Ukraine strikes Russian plant producing missile, bomb batteries in Yelets, General Staff

The two soldiers, 25-year-old Yevhen, call sign "Izium," and 24-year-old Artem, call sign "Kolobok," had suffered severe limb injuries and were stranded in a contested area about 5 kilometers (3 miles) from the Russian border.

Russian forces are preparing to resume mechanized assaults in southern Ukraine after a pause of several months and are moving armored vehicles toward areas where they plan to launch offensives, Anastasiia Shevchenko, deputy spokesperson for the Southern Forces Grouping, told Ukrinform on 22 October. The Huliaipole axis remains the hottest in the Southern grouping’s zone, with 10 to 20 combat engagements reported on an average day, she said.

On the Huliaipole axis, one of Russia’s largest force groupings is fighting Ukrainian forces, comprising units from several Russian combined-arms armies, the spokesperson says. Over the past week, as the weather worsened, Russian forces began local assaults there with infantry, motorcycles, and armored vehicles, seeking to break through toward Zaporizhzhia and blockade the city, Ukraine’s 7th Air Assault Corps reported, adding that the area is one of Russia’s key priorities in southern Ukraine. Russia has used fog this way before: last November, Russian troops moved under its cover to avoid detection by Ukrainian drones as they advanced on Huliaipole, the Institute for the Study of War assessed.

Russian forces have abandoned large-scale assaults across a broad front and are attempting to infiltrate Ukrainian positions in small groups. They periodically use motorcycles and quad bikes for assaults, Shevchenko said, adding that these vehicles are fast and maneuverable.

However, Russian forces should not expect to advance unimpeded, the spokesperson noted. Ukrainian units control Russian supply routes and systematically detect and strike Russian personnel and equipment while they are still moving toward their launch positions, she added.

“Specifically, speaking in numbers, since the beginning of October alone, units of the Southern Forces Grouping (Forces) have destroyed more than 3,000 occupiers and 1,300 pieces of weapons and military equipment. Thus, the enemy is suffering significant losses in the operational zone of the Southern Forces Grouping (Forces),” the spokesperson concluded.

Ukrainian drones disrupt Russian logistics

Russian forces had stopped using military vehicles because Ukraine’s unmanned systems forces controlled their logistics, Shevchenko said in comments to Ukrinform on 16 September. Ukrainian drones spotted Russian troops and equipment in time and struck them mostly on their routes of advance, she said.

Ukrainian air strikes destroyed bridges near Polohy in Zaporizhzhia Oblast, complicating Russian supply operations along the Huliaipole axis, Ukraine’s 7th Air Assault Corps reported on 21 September. Russian forces had used these bridges to move personnel, heavy equipment, and ammunition for their offensive toward Orikhiv. Disruptions to logistics have forced Russian units to rely more on motorcycles, which are more vulnerable to Ukrainian strikes, the corps said.

Russian forces are also expected to use fog and rain as cover for assaults, Mykola Zinko, deputy commander of the unmanned systems battalion of the 5th Assault Brigade, said on 19 October. Russia has brought up reserves, and its heavy equipment will move out under the fog, he said.

The corps said more than 30 Russian soldiers were captured during the operation and Russian forces suffered more than 100 casualties.

Ukrainian forces have liberated more territory since the beginning of the fall than Russian troops have captured during the same period. This trend has persisted throughout 2026, Ukrainian President Volodymyr Zelenskyy said in his 18 October address. He also reported that Dobropillia, Kostiantynivka, and five other settlements remain under Ukrainian control.

Russia systematically exaggerates its battlefield gains. A recent briefing by Valery Gerasimov, chief of the General Staff of the Russian Armed Forces, in which he claimed that Russian forces had captured 92 settlements since the beginning of September, as well as Kostiantynivka and Dobropillia, and advanced to within 5 kilometers of Zaporizhzhia, was based on “outright lies, manipulation, and exaggerations,” Ukrainian General Staff spokesperson Andrii Kovaliov said.

Ukraine also continues to defend areas near Kramatorsk, Zelenskyy said. He dismissed Russian claims about Zaporizhzhia.

“We are destroying Russians 20 kilometers from Zaporizhzhia, not five, as someone in Russia is fantasizing to Putin,” Zelenskyy said.

Ukrainian forces continue to hold back Russian assaults and destroy groups of occupying troops attempting to infiltrate Dobropillia, the president said. The Defense Forces are also defending positions elsewhere in Donetsk Oblast and in Kharkiv and Zaporizhzhia oblasts.

Zaporizhzhia axis: Russians seek to move artillery closer to the city

Russia seeks to advance on the Zaporizhzhia axis to bring the regional capital within range of its tube artillery, hold forward positions, and protect rear areas from Ukrainian strikes, the Institute for the Study of War (ISW) said on 18 October.

Maksym Kravchuk, spokesperson for Ukraine's Southern Group of Forces, refuted Gerasimov’s claims that Russian forces had captured Malokaterynivka, located south of Zaporizhzhia, stressing that the settlement remains under Ukrainian control, the Center for Countering Disinformation said on 18 October. Ukrainian troops recorded a video directly from Malokaterynivka to confirm this.

As of 18 October, Russian forces had advanced or infiltrated to within 24 kilometers of Zaporizhzhia, ISW said.

Dobropillia remains under Ukrainian control despite Russian assaults

Dobropillia is now a fortress anchoring Ukrainian positions along the highway leading northeast toward Kramatorsk. Russia first tried to take Dobropillia in August 2025 and is now trying again.

Russia is redeploying reinforcements to the Dobropillia axis and continues to send assault infantry through the village of Nove Shakhove despite heavy losses. Russian command will likely try to encircle or at least envelop Dobropillia and cut off Ukrainian supply routes from the direction of Bilozerske, Ukrainian military analyst Kostiantyn Mashovets wrote on 9 October.

Mashovets sees the push as the southern flank of a Russian effort to envelop the whole Sloviansk–Kramatorsk urban area.

Dobropillia remains under Ukrainian control, Zelenskyy said. On 18 October, footage located by analysts showed a Russian soldier hoisting a flag in the town's southeast after an infiltration, yet ISW has found no sign that Russian troops have dug in there.

Russia claimed to have captured Kostiantynivka, but ISW found no evidence

Ukrainian troops in and around Kostiantynivka are stopping Russia from locking in its gains in the city or pushing on toward Druzhkivka and Kramatorsk, ISW said on 17 October.

Russian officials claimed that capturing Kostiantynivka was an important step toward establishing control over the Sloviansk–Druzhkivka–Kramatorsk urban agglomeration and the entire Donetsk Oblast, ISW said in August. The Kremlin also claimed that Russian forces had captured the city as early as 5 July, the institute added.

A Russian military blogger claimed that Russian forces had full control over Kostiantynivka, but ISW found no evidence to support this claim, the institute said in its 16 October assessment. Russian troops had only infiltrated parts of southern and central Kostiantynivka without consolidating positions, and there was no evidence of their presence in its northern part, ISW added.
