Direct proof of use
The 120 KRH 92 appears in the 2014 Russia-Ukraine War through open-source reporting from August 2022 that placed Finnish-made 120 mm heavy mortars in Ukrainian Defense Forces possession. Militarnyi reported on 16 August 2022 that OSINT researchers had identified 120 KRH 92 mortars with Ukrainian forces from a photo showing mortar use.
Army Recognition repeated the identification the next day and described the photographed weapon as a Finnish-made Vammas 120 KRH 85/92 mortar of the Ukrainian army. Oryx's Finland aid tracker later listed 120 mm 120 KRH 85/92 heavy mortars among Finnish-delivered armament observed in Ukrainian use.

Transfer and fielding
The public record supports Ukrainian fielding but not an exact delivery date, quantity, unit assignment, or battlefield location for the photographed mortars. The first published identification came in mid-August 2022, several months into Russia's full-scale invasion, and Oryx grouped the mortars with Finnish military aid whose contents were partly reconstructed from observed equipment.
Finland's Ministry of Defence states that Finland provides defence materiel assistance to Ukraine but does not give detailed information on contents, delivery methods, or schedules for operational reasons and to ensure deliveries reach their destination. That official policy explains why the 120 KRH 92's Ukrainian-service record is based on observed equipment rather than an itemized Finnish announcement naming the mortar.

Battlefield role
In Ukrainian service, the 120 KRH 92 filled a conventional heavy-mortar fire-support role. The photographed and cataloged system was a 120 mm towed mortar, and the conflict-specific reports identify it as Ukrainian mortar equipment rather than as a vehicle, launcher, or precision strike system.
The same reporting describes the 120 KRH 92 as a Finnish-made Vammas mortar and gives public performance context: a roughly 500 kg towed system with a 2 m tube, a 12-15 round-per-minute rate of fire, and a 0.25-7.5 km firing range. Those figures support the role description but do not by themselves prove a separate firing incident beyond the August 2022 photographic identification.
