Russia suffered vastly more casualties than Ukraine in September, a senior NATO military official told Bloomberg. Ukraine’s General Staff put the month’s Russian toll only slightly lower.

September’s toll lands on a recruitment system that was already falling short. Ukraine’s military intelligence (HUR) estimated that Russian losses outran new contracts in June and July, when monthly losses ran lower. In August, Ukrainian President Volodymyr Zelenskyy, citing military intelligence, warned that Russia is preparing a mass call-up after its parliamentary elections. That vote ended on 20 September.

Where the numbers come from

Russian casualties passed 50,000 in September, up to 28,000 of them killed, the official said. Ukraine’s losses over the same month came to about 5,000, according to the official, who spoke on condition of anonymity. Russia does not release casualty figures, Bloomberg noted. In late August, Pavlo Palisa, deputy head of Ukraine’s Presidential Office, put Russia’s July losses at 43,000 killed and wounded. Bloomberg could not confirm his figures.

To push forward, Russia keeps feeding troops into “kill zones,” the official said. These are stretches of ground saturated with armed drones, mines, and artillery fire. Maksym, call sign Rumyn, is a deputy company commander in the 46th Airmobile Brigade’s drone battalion. In April, he said the zone once ran 3–5 km deep and is now several times larger.

Rising stakes for Moscow

Russia’s defense spending is expected to near $199 billion this year, Bloomberg reported, citing two sources close to the government. That is about 40% above the plan the government set in late 2025.

Russian President Vladimir Putin would struggle to wind down the invasion without a political cost, Martin Jäger said last week. He heads Germany’s Federal Intelligence Service (BND).

Lithuania plans to deploy up to 100 soldiers to support border guards along its frontier with Russia's Kaliningrad Oblast, Defense Minister Robertas Kaunas said on 7 October.

Lithuanian Interior Minister Martynas Katelynas has described the deployment as a preventive measure linked to possible Russian mobilization and a recent incident on the Latvia-Belarus border, where masked, armed escorts tried to push a group of migrants into Latvia. Katelynas said Lithuania could face people trying to avoid mobilization and seeking asylum.

Kaunas said he had granted permission to use Lithuanian soldiers to strengthen border protection for the next several weeks.

 “The order starts being implemented immediately,” he wrote on Facebook.

Russia denies a new mobilization

The Kremlin denies a new mobilization is coming. In early September, Russian President Vladimir Putin called reports of one "complete nonsense" and "an information attack on Russia." Ukraine's military and foreign intelligence services say Russia's General Staff has prepared a scenario to mobilize 600,000 people over 2026 and 2027. On 28 September, President Volodymyr Zelenskyy said that "in effect, the Russians have already begun additional mobilization."

Frontier-station patrols for a couple of weeks, possibly longer

On 8 October, the Lithuanian army said soldiers were being brought in to help the State Border Guard Service from that day. A company-sized unit was planned for the assignment, initially for two weeks, with the option to extend. Soldiers will patrol with border guards in frontier-station areas, while mobile patrols, mobile observation posts, and military police crews may be added as needed. The army described the deployment as preventive and a normal form of interagency cooperation.

Kaunas had told LRT TV the soldiers would stay until 16 October. On the morning of 8 October, he said the deployment "was supposed to start" overnight and that he would check with the army. On 8 October, the Lithuanian army said soldiers were being brought in to help the State Border Guard Service from that day. Kaunas also said that “on the Kaliningrad side” there were no physical barriers, unlike the border with Belarus.

Lithuania says its border guards are stretched

On 8 October, Katelynas said the border guard service’s capacity was insufficient, with shifts growing while officer numbers were not increasing. He said the threat level had not changed. In a Facebook post the previous day, he said the situation at Lithuania’s border was calm and there was no reason to panic. He said Russia was planning mobilization after the elections and that Lithuania may face people trying to avoid it and seeking asylum.

Lithuania's State Border Guard Service had turned back 1,693 people trying to cross illegally from Belarus this year and about 26,300 since the migration crisis began, as reported by ELTA on 8 October. Katelynas said 43 migrants tried to enter southern Lithuania last week and were turned back.
