Russian penal military units during the Russian invasion of Ukraine

• 1. Recruitment Campaigns And Scale

  ›

  The Foreign Intelligence Service of Ukraine claims Russia has recruited between 140,000 and 180,000 convicts to fight in Ukraine. The Russian paramilitary Wagner Group began recruiting from prisons starting in 2022. Their forces grew by an estimated 40,000 men during this period. According to the New York Times, Wagner's prison recruitment campaign started in early July 2022. Prigozhin personally appeared in prisons around St. Petersburg to offer deals to inmates. This effort expanded rapidly before the group lost access to prisons in February 2023. Schisms with the regular Russian Ministry of Defense caused this cutoff. The Russian MoD itself reportedly began recruiting prisoners in October 2022. By June 2023, the Institute for the Study of War noted a significant increase in Ministry of Defense prison recruitment. This surge came after significant losses in Ukraine. In April 2023, information emerged about the creation of Storm-Z units by the MoD. These units received only ten to fifteen days of training before deployment.

  Yevgeny Prigozhin described recruits as shock troops who would lead attacks and take heavy casualties in a September 2022 speech. Experts and captured Wagner soldiers stated prisoner recruits were used as little more than cannon fodder. Thousands of Wagner convict soldiers played a key role in the Battle of Bakhmut. They took part in wave attacks against Ukrainian positions. Ukrainian media reported that convicts are dumped onto the front after two to three weeks of poor training. Elite, well-trained Wagner group commanders often use these men as disposable assets. British intelligence noted that Russian commanders punish soldiers who abuse drugs and alcohol by forcing them to fight in Storm-Z detachments. By March 2023, the British Ministry of Defense said about half of recruited Wagner prisoners had been killed or wounded in Ukraine. The Institute for the Study of War observed in February 2025 that Russia had mostly exhausted its prison population in 2022 and 2023. The government could no longer generate significant forces from inmates at that time.

• 3. Human Rights Violations And Discipline

  Prigozhin warned any prisoner attempting to flee service would be considered a deserter and shot during his September 2022 speech. United Nations experts expressed concern over allegations that recruits are regularly threatened and ill-treated by their superiors in March 2023. Reports indicated several recruits have been executed for attempting to escape. Other cases involved serious injuries inflicted publicly as warnings to other recruits. These tactics were described as human rights violations that may amount to war crimes. In November 2023, British intelligence noted that drug and alcohol abusers faced punishment through forced combat in Storm-Z detachments. The United Kingdom's Ministry of Defense described recruitment as part of a broader effort to bolster numbers without implementing unpopular mandatory mobilization. This strategy avoided direct public backlash while utilizing criminal populations. The Institute for the Study of War noted in February 2025 that the Russian government deprived volunteers of one-time enlistment bonuses starting the 1st of January 2025. This financial cut removed incentives for new recruits joining the front lines.

• 4. Legal Framework And Unit Evolution

  ›

  Vladimir Putin signed a law on the recruitment of convicts to contract service with the Defense Ministry on the 24th of June 2023. This legislation disbanded Storm-Z units and replaced them with new Storm-V units. The transition occurred after Wagner lost access to prisons following internal conflicts. Storm-Z units attached themselves to regular Russian forces suffering from battle fatigue. They received only ten to fifteen days of training before deployment. While many prisoners recruited by Wagner and Storm-Z were guaranteed release if they survived their six-month term, those joining Storm-V must serve until the end of the conflict. The legal shift marked a formal integration of penal units into state military structures. It ended the private contractor model used by Prigozhin's group. The change reflected a need for more stable command over these volatile forces. New regulations aimed to standardize treatment and duration of service across all convict detachments.

• 5. Post-Service Consequences And Release

  ›

  Under the Wagner model, prisoners who survive a six-month term on the front are released into Russian society. They receive a pardon for their crimes upon completion. Many of the released men are hardened criminals who pose risks to public safety. Russians fear that freed individuals will continue committing more crimes in civilian life. In August 2023, a convicted criminal freed after fighting with Wagner was arrested for stabbing six people to death. This incident occurred in the town of Petrozavodsk in Russia's Republic of Karelia. Olga Romanova of Russia Behind Bars stated there are no more crimes or punishments under this policy. She argued anything is permissible now and brings far-reaching consequences for any country. The Institute for the Study of War noted in February 2025 that Russia had mostly exhausted its prison population in 2022 and 2023. The government could no longer generate significant forces from inmates at that time. Financial incentives were removed starting the 1st of January 2025 to curb recruitment efforts.
