Defense Express reported the information.The U.S. Army’s Foreign Military Studies Office (FMSO) has analyzed the battlefield from February 2022 through July 2024 and concludes that Russia’s campaign in Ukraine hinges on mass, improvisation and brutality rather than professional readiness or high-tech precision.Drones as front-line eyes and weaponsSmall UAVs have effectively replaced traditional forward observers, guiding artillery and carrying improvised munitions. Russian units need tens of thousands of drones each month, yet sub-battalion formations still buy or build them on their own because centralized procurement is scant.Electronic warfare shapes the fightSystems such as Leer-3 and Borisoglebsk are used not merely to protect units but to “soften” entire sectors before major assaults. Cheap $20 commercial jammers have reportedly degraded the accuracy of JDAM-ER bombs and Excalibur rounds.Artillery over everythingRussia’s doctrine of “artillery first” has evolved into large “army artillery groups” that pair with drones to scorch paths for assault troops. The emphasis on volume fire over precision remains the backbone of every major thrust.Adaptive units, whole-of-society mobilizationElite formations strive to preserve a professional core while newly mobilized regiments learn trench-warfare tactics dominated by UAVs. Meanwhile, the Kremlin has harnessed schools, volunteers and propaganda to keep manpower and matériel flowing to the front.Bottom line, say U.S. analysts: the Russian way of war thrives on mass, speed of adaptation and an economy of scale—even if it bleeds equipment and people at staggering rates. The finding is already shaping Pentagon thinking, pushing the U.S. Army to weave drones into every echelon and tighten its own “sensor-to-shooter” decision loop.
