Russia's Military Casualties and Covert Mobilization Efforts in Ukraine

12/13/2025, 11:02:44 PM

Overview of Military Losses

Since the onset of its full-scale invasion of Ukraine on February 24, 2022, Russia has reportedly suffered approximately 1,187,780 military casualties, according to the General Staff of Ukraine's Armed Forces. This figure includes around 1,300 casualties reported over a single day as of December 13, 2023. In addition to personnel losses, Russia has experienced significant equipment losses, including 11,409 tanks, 23,714 armored fighting vehicles, and 35,032 artillery systems, among other military assets.

Current Military Situation

Despite these heavy losses, Russian forces have claimed control of the city of Pokrovsk in the Donetsk region after months of intense fighting. However, Ukraine asserts that it still maintains a presence in parts of the city. As of now, Russia controls approximately 19% of Ukrainian territory, but these gains have come at a substantial human cost, with both sides continuing to escalate their military operations as winter approaches.

Covert Mobilization Initiatives

In response to mounting casualties, Russian President Vladimir Putin has initiated a new phase of covert mobilization. On December 8, 2023, he signed a decree calling up reservists for military training assemblies scheduled for 2026. Analysts from the U.S.-based Institute for the Study of War (ISW) interpret this move as an effort to replenish the dwindling ranks of Russian forces in Ukraine. The decree allows for the mobilization of reservists across various military and security agencies, although specific details regarding the number of individuals to be called up remain classified.

Implications of Mobilization

The ISW has indicated that this new mobilization strategy is likely a response to the near exhaustion of Russia's voluntary recruitment system, which currently yields about 30,000 troops per month—an amount comparable to the estimated monthly casualties in Ukraine. The Kremlin's approach aims to avoid a large-scale mobilization while incrementally drawing on reservists. This strategy is complemented by recent legislation that facilitates the call-up of reservists for "special assemblies," allowing for up to two months of paid service outside of formal wartime conditions.

Criticism & Opposition

Critics of the Russian government's military strategy argue that the ongoing losses and the need for covert mobilization reflect a failure of the initial invasion strategy. The reliance on reservists and the introduction of new laws to facilitate recruitment suggest a deepening crisis within the Russian military structure.

Verbatim Quotes

  • “In addition, ISW stated that the Kremlin is “very likely” preparing to offset the near exhaustion of voluntary recruitment by mobilizing elements of Russia’s strategic reserve while avoiding a single large-scale mobilization and instead drawing in reservists on a rolling basis.” — Institute for the Study of War
  • “The assemblies scheduled for 2026, which will be held in winter, will allow the Kremlin to “secretly mobilize” members of the “strategic inactive reserve” at a time when Russia’s pool of volunteers and contract soldiers is close to exhaustion.” — The Moscow Times

Conflicting Reports & Gaps

While the General Staff of Ukraine's Armed Forces provides detailed casualty figures, there is no independent verification of these numbers, and Russian sources have not confirmed the extent of their losses. Additionally, the specifics of the mobilization decree, including the number of reservists to be called up, remain undisclosed.

This ongoing conflict continues to evolve, with both sides preparing for a challenging winter as discussions of peace plans unfold among international stakeholders.
