Russia's effort to build a larger military is colliding with the realities of a grinding war that has already inflicted severe personnel losses and strained the Kremlin's ability to replace them. As Moscow continues to sustain high casualties in Ukraine, the challenge is no longer only how to field more troops, but how to persuade enough men to join a war that has become synonymous with attrition, uncertainty and death.
Recruitment Under Strain
The Kremlin has spent much of the war trying to avoid a politically costly nationwide mobilization, relying instead on contract soldiers, regional incentives, prison recruitment and other stopgap measures. That approach has helped Moscow keep the front lines staffed without triggering the kind of domestic backlash that followed the partial mobilization in 2022. But the longer the war drags on, the harder it becomes to sustain that model.
Heavy losses have reduced the appeal of military service, especially for men who see the risks but not the rewards. Even where pay and benefits have been raised, recruitment remains a difficult sell in a society increasingly aware of the war's human cost. The problem is compounded by reports of repeated deployments, poor equipment, and the perception that new recruits are being fed into a war of exhaustion rather than a campaign with a clear end state.
For Putin, the dilemma is strategic as much as political. Russia's military leadership wants depth: more infantry, more reserves, and more manpower to rotate exhausted units. Yet every effort to expand the force risks exposing the scale of losses and the limits of the state's ability to compensate for them through money alone.
Zelenskyy Flags New Moves
Ukrainian President Volodymyr Zelenskyy has said Russia has already begun additional mobilization, warning that Moscow is seeking to replenish its ranks despite the public sensitivity of the issue inside Russia. His comments come as Kyiv and its partners watch for signs that the Kremlin may be preparing a broader manpower push to support operations along the front.
Zelenskyy has also said North Korea is preparing to deploy another 10,000 troops to Russia, a claim that, if confirmed, would underscore how far Moscow is reaching beyond its own borders to sustain the war. The reported involvement of North Korean personnel would deepen concerns that Russia is increasingly dependent on external support and irregular manpower channels to offset battlefield attrition.
Such reports fit a broader pattern: Russia has repeatedly sought ways to blunt the impact of losses without acknowledging the full scale of the strain. That includes drawing on regional recruitment drives, financial bonuses, and opaque enlistment practices that obscure the true cost of the war from the wider public.
War Of Attrition Deepens
The manpower challenge is central to the current phase of the conflict. Russia's military can still absorb losses better than Ukraine in sheer demographic terms, but that advantage is not unlimited, and it is being eroded by the intensity of combat. Every additional offensive push requires fresh troops, and every fresh troop requires training, equipment and a willingness to serve in a war with no easy victory.
The Kremlin's recruitment problem also has diplomatic implications. If Moscow is indeed turning to North Korea for more personnel, it would reinforce the image of Russia as increasingly isolated and reliant on sanctioned or authoritarian partners. That could complicate any future effort by Putin to present the war as a controlled, sustainable national project.
For now, the Russian leadership appears determined to keep expanding military capacity without resorting to a politically explosive full mobilization. But the arithmetic of war is unforgiving. The more soldiers Russia loses, the harder it becomes to replace them quietly, cheaply and at scale. That tension now sits at the center of Putin's war effort, and it may shape both the battlefield and the Kremlin's domestic calculus in the months ahead.
