Russia consolidated several units composed of Ukrainian prisoners of war and alleged defectors into a single brigade and labeled it "volunteer," the Institute for the Study of War (ISW) reported. The move scales up a practice ISW has tracked since 2022, when Moscow first began pressing captured Ukrainian soldiers into combat formations. ISW assessed the practice as a likely violation of the Geneva Convention, which bars using prisoners of war in military operations.

Moscow merges five POW units into one brigade

Russia's Defense Ministry Volunteer Corps announced on 6 August that it had formed the "first Ukrainian Volunteer Spetsnaz Brigade." The formation absorbed at least five existing units: the "Maksim Krivonos" and "Aleksei Berest" battalions, and the "Aleksandr Matrosov," "Martyn Pushkar," and "Slobodskoy" detachments. Each of these units reportedly drew members from captured Ukrainian soldiers or Ukrainians who allegedly defected to Russia.

The Volunteer Corps framed the new brigade as a formation of willing participants. At least one Russian military blogger, however, openly stated the brigade is composed of Ukrainian prisoners of war. ISW noted the admission as significant.

ISW: Russia officially deploys Ukrainian POWs to front lines

One of the merged units, the Krivonos battalion, previously figured in a Russian propaganda operation. Moscow presented a Polish citizen as a defector to that battalion in 2025. Months later, a court in occupied Luhansk Oblast sentenced the same man to 13 years as a mercenary.

A practice ISW has tracked since 2022

ISW first documented Russia forming combat units from Ukrainian prisoners in November 2022. The most recent confirmed case before this brigade was the Bogdan Khmelnitsky battalion, which operated as part of the DNR interior ministry's Kaskad unit in western Donetsk Oblast starting in December 2023.
