An analysis of battlefield data indicates Russia achieved its largest territorial gains in Ukraine since 2022 during 2025, capturing over 5,600 square kilometers. This advance, representing about 0.94% of Ukraine's landmass, occurred through attritional tactics, including heavy artillery, drone warfare, and infantry assaults, rather than rapid expansion. The gains highlight Russia's ability to leverage sustained pressure against Ukrainian forces facing manpower and equipment shortages, marking a shift from the initial invasion's strategy.
