The RG-31 Nyala's documented role in the 2014 Russia-Ukraine War is the Spanish-donated armored ambulance supplied to Ukraine after Russia's February 2022 full-scale invasion. El Pais reported on March 27, 2022 that Spain was sending an armored ambulance on an A400M flight for evacuating wounded personnel from areas threatened by Russian forces.
InfoDefensa reported on April 1, 2022 that Ukraine had received the RG-31 ambulance donated by Spain after transport by A400M and handover near the Ukrainian border. A March 2023 Spanish Defence Ministry statement later listed an RG31 armored ambulance among the material Spain had sent to Ukraine.

Timeline
The public record places the transfer in late March and early April 2022. Spain prepared the shipment in the same early-war aid stream as additional weapons and ammunition, then Ukrainian forces received the vehicle after air transport to the Polish-Ukrainian border area.
Oryx's inventory of Spanish military aid to Ukraine separately lists one RG-31 Nyala ambulance delivered in April 2022, matching the delivery window reported by Spanish defense media.

Operational role
The sources identify the Ukraine vehicle as an ambulance rather than a troop-carrier or weapons-carrier configuration. Its conflict role was protected medical movement: carrying wounded personnel under armor and mine protection in a war zone where evacuation routes could be exposed to shelling, mines, or Russian ground threats.
InfoDefensa described the vehicle as an RG-31 ambulance version with medical evacuation fittings, including stretcher handling, oxygen-related equipment, storage, lighting, siren equipment, and the removal of the external machine-gun installation normally associated with armed RG-31 variants.
