The M120 Rak is documented in Ukrainian service during the 2014 Russia-Ukraine War through Polish-Ukrainian transfer reporting, brigade-level imagery and video, and later official Ukrainian Ministry of Defence reporting.
OSW reported that agreements signed during President Volodymyr Zelensky's April 2023 Warsaw visit included three Rak fire modules for Ukraine, totaling 24 120 mm self-propelled mortars with protection vehicles. Defense Express then identified December 2023 video from Ukraine's 44th Separate Mechanized Brigade as the first public video of the Polish 120 mm Rak in the Armed Forces of Ukraine.

Timeline
The public sequence begins with the April 2023 Polish-Ukrainian procurement announcement, followed by December 2023 brigade imagery and video showing Rak vehicles in Ukrainian hands. In September 2024, Defense Express, citing ArmyInform interviews with Ukrainian crews, described Rak mortars as already in service for at least a year and a half and tied them to soldiers of the 44th Separate Mechanized Brigade.
On 14 May 2026, Ukraine's Ministry of Defence stated that the Defence Forces of Ukraine operate the Rak self-propelled mortar system alongside Rosomak combat variants. That official account confirms the system's continuing Ukrainian service but does not give a vehicle count or assign all Rak vehicles to a single unit.

Battlefield role
In the Ukraine record, Rak appears as a mobile 120 mm mortar fire-support system supplied by Poland and operated by Ukrainian forces. Defense Express reported that 44th Brigade personnel described its task as supporting infantry and destroying fortified positions, while later ArmyInform-based reporting emphasized Ukrainian crew use against Russian infantry targets spotted by reconnaissance drones.
The sources support a fire-support and foreign-aid fielding role, not a complete order of battle. They document transfer plans, public brigade appearances, crew comments, and Ukrainian MOD confirmation of operation, but they do not establish a full delivery total in service, a complete list of Ukrainian units, or a verified incident-by-incident firing log.
