Conclusion
Russia’s force generation has failed to give Moscow the decisive advantage it expected. Faced with the challenge of overcoming a traditional prepared defense, Ukraine’s adaptation, and Western aid, Russian forces struggled to put the pieces together and attain meaningful breakthroughs or create localized Ukrainian collapse. The growing presence of mass precision on the battlefield further strengthened the defender’s advantage, as Russian force quality and ability to employ forces at scale declined. What the Russian General Staff would have assessed to be an increasingly advantageous correlation of forces over time has never materialized despite chronic Ukrainian manpower shortages. Hence, lofty operational goals consistently went unrealized, as Russian forces could not execute those plans at the tactical level.
Ukraine’s battlefield dynamics deny Russian forces many of the traditional advantages of numbers: Russian commanders cannot mass forces with sufficient speed or surprise to create localized overmatch, and the ubiquitous drone threat in combination with traditional prepared defenses compels Russian forces to attack at below platoon and even squad-strength in most cases. Russian leadership has pursued two and a half years of a broad grinding offensive, assuming that eventually the Ukrainian military would break, and they would achieve their operational goals. Instead, this effort yielded higher costs and diminishing returns as Ukraine consistently adapted over time and optimized to defeat the Russian approach.
Arguably, the steady pipeline of replaceable manpower made senior Russian commanders complacent, reinforcing a cost-ineffective approach. Many Russian combined-arms armies, which doctrinally would have an area of responsibility measured in hundreds of square miles, cover a 20- to 30-mile section of the front in Ukraine. This concentration stretches down to the lowest echelon — brigades of several thousand troops are now often responsible for advancing along a ravine or ridgeline or for seizing one or two small villages. Yet Russian combat power is so disaggregated by drone, mine, and artillery threats that only a tiny fraction of that brigade’s combat strength is usable at any given point in time. Furthermore, Russian force quality continued to degenerate from 2022. Its inability to progress on the battlefield is therefore a combination of being unable to overcome Ukrainian defense, and its own underinvestment in restoring the ability of the force to conduct more complex offensive operations. The Russian approach had a clear tradeoff, by focusing on sustaining a constant pace of offensive operations via replaceable low-quality assault units, the Russian military focused on mass at the expense of restoring force quality, which made it more vulnerable to Ukrainian counter-adaptation.
At this stage of the war, it is not clear if more forces would fix anything for Russia, unless its military changes the method of employment. Absent this additional mass, Moscow’s choices for breaking the battlefield stalemate are now limited. Furthermore, the cracks in Russia’s current force generation model started to show in late 2025. Russian regions must keep increasing bonuses to meet recruitment targets, which is becoming fiscally untenable. If casualty rates continue to increase, the Russian force in Ukraine will probably begin to contract, meaning that Moscow has moved past its high-water mark for offensive capacity.
How much of this force the Russian military will be able to retain also remains uncertain and subject to budgetary constraints. What is clear is that the Russian military seems to have made a profound miscalculation, assuming that force quantity would eventually offset Western support and Kyiv’s innovations and wear down Ukraine. In reality, how it employed force over time led to declining combat efficiency and effectiveness, closing a window of opportunity that was open in 2024 and 2025.
