The Russian military is facing a protracted period of slow, high-cost advances as it remains unable to generate the strategic reserves necessary for a major breakthrough. According to a year-end report, the Kremlin’s current recruitment pace is largely dedicated to replacing staggering battlefield losses, leaving Moscow with few options for expanding the scale of its offensive operations through the coming year.
Why It Matters
The inability to form a strategic reserve suggests that the conflict remains a grueling war of attrition rather than one of rapid maneuver. For Ukraine and its Western allies, this indicates that Russia’s offensive potential has a ceiling, provided that defensive aid continues. Without the ability to surge fresh units without thinning existing lines, the Russian military remains vulnerable to localized counterattacks in sectors where resources have been diverted.
What to Know
According to the latest assessment by the Institute for the Study of War (ISW), Russian forces are currently sustaining manpower inflows sufficient to replace casualties but lack the surplus required to seize significant new territory. Analysts note that when Russia attempts to push in one sector, it is often forced to redeploy troops from others, leaving its flanks undermanned.
This operational strain has already led to tactical setbacks for Moscow. In early November, while Russian forces were focused on the city center of Huliaipole, Ukrainian troops successfully liberated territory to the north. Similarly, Ukrainian units reclaimed ground on the Dobropillia axis during the Russian push toward Pokrovsk, and regained much of Kupiansk because Russian forces were concentrated elsewhere with no ready reserves to plug the gaps.
While Russia has transitioned its military structure toward positional warfare, it has struggled to adapt back to the maneuver warfare required for large-scale operational advances. Consequently, the ISW suggests that Russia is currently unable to open a new front or significantly expand its limited attacks in regions like Sumy and Kharkiv.
What People are Saying
Kyrylo Budanov, head of Ukraine’s military intelligence agency, recently noted that Russia has met its 2025 recruitment goal of 403,000 troops and will likely exceed it. He anticipates that Moscow will aim to increase mobilization to 409,000 in 2026, citing Russia’s vast population and financial resources as tools for long-term recruitment.
However, ISW analysts emphasize that recruitment numbers do not equate to strategic depth. While the Kremlin may attempt to form a reserve, persistently high casualty rates continue to act as a “hard cap” on growth. Despite these logistical realities, Russian President Vladimir Putin continues to project confidence, making claims regarding battlefield progress that analysts describe as misleading, often suggesting that Russian forces are prepared to escalate at any moment.
What Happens Next
The trajectory of the war in 2026 appears set for a continuation of incremental, costly gains for Russia rather than a dramatic shift in the front lines. Experts believe that the Russian army will face slow advances in Ukraine throughout the next year if Western support for Kyiv remains at current levels. Unless the Russian Defense Ministry can solve its reserve deficit without compromising existing defensive positions, the Russian military is unlikely to increase the pace or scale of its offensive operations in the near future.
