Direct proof of use
The KTO Rosomak is documented in Ukrainian service in the 2014 Russia-Ukraine War through official Polish and Ukrainian supply statements, later Ukrainian Ministry of Defence service reporting, and defense reporting on first brigade appearances.
Poland announced on 1 April 2023 that Ukraine had placed an order for 100 Rosomak combat vehicles. Four days later, Ukraine's presidential office said a letter of intent covered Polish Rosomak armored personnel carriers and Rak self-propelled mortars. By August 2023, Army Recognition reported Rosomaks with Ukraine's 21st Mechanized Brigade and described them as being used to fight Russian troops near the Kreminna area.

Timeline
The public record starts with a March-April 2023 procurement and supply sequence, followed by fielding reports in Ukrainian brigades later that year. September 2023 reporting cited U.S. Secretary of Defense Lloyd Austin as saying Poland had provided about 100 Rosomak APCs to Ukraine, while noting that the exact mix of variants was not publicly clear.
A separate March 2024 report tied the Rosomak chassis to Ukraine's use of Polish Rak 120 mm self-propelled mortar carriers after images from Ukraine's 44th Brigade. In May 2026, Ukraine's Ministry of Defence described Rosomak vehicles as having been in Defence Forces service for several years and said Ukrainian forces operated both the Hitfist-30P combat variant and the Rak self-propelled mortar system.

Battlefield role
In Ukrainian service, public sources describe the Rosomak family primarily as a protected wheeled armored vehicle for mechanized infantry mobility, with fire-support roles depending on variant. Ukraine's Ministry of Defence says the vehicle can be adapted from medical evacuation to fire support, identifies the widely used Hitfist-30P combat variant, and states that Ukrainian forces also operate the Rak self-propelled mortar system.
The evidence does not support treating every Rosomak-related item as the same battlefield configuration. Sources separate the APC/IFV vehicles supplied or fielded with mechanized brigades from Rak mortar carriers on a Rosomak chassis, and Defence24 noted that public information did not clearly identify the proportions of the variants transferred to Ukraine.
