Direct proof of use
The C90-CR-RB (M3.5) is documented in the 2014 Russia-Ukraine War through Spanish reporting on Spain's first 2022 arms shipment and early images of Ukrainian personnel with Spanish C90 launchers. El Independiente identified the weapon shown in Ukrainian hands as a C90-CR-RB made by Instalaza, while El Espanol and Infodefensa reported that Spanish C90 launchers from the aid shipment had reached Ukrainian forces.
The available open-source record directly supports transfer, delivery, possession, distribution, and battlefield availability of Spanish C90 anti-tank launchers in Ukrainian service. It does not provide a complete accounting of individual C90-CR-RB (M3.5) firings or expended rounds.

March 2022 transfer and appearance
On March 3, 2022, Reuters reported Spanish defense minister Margarita Robles saying that Spain would send 1,370 anti-tank grenade launchers, 700,000 rifle and machine-gun rounds, and light machine guns on two aircraft to a location in Poland where Ukrainian officials would collect them.
By March 7, Spanish outlets reported that the C90 launchers had reached Ukrainian hands. Infodefensa described a batch of 1,370 C90 anti-tank launchers from Spain's first arms shipment and said the materiel was already on Ukrainian soil. El Independiente reported that those launchers had been distributed among Ukrainian volunteers and armed forces, and identified the C90-CR-RB designation in the same report.

Role in Ukrainian service
In Ukrainian service, the weapon's documented role was a lightweight, disposable anti-armor round supplied as foreign military aid during the first weeks of Russia's 2022 full-scale invasion. El Independiente described the Spanish C90s as especially useful against tanks, while Instalaza lists the RB load as the anti-tank munition in the C90-CR (M3.5) family.
Later open-source summaries and video references describe Spanish C90 launchers being used in ground fighting, including reporting around a Russian vehicle near Dronivka. Those accounts support broader C90 combat use, but they are less precise about the exact RB/M3.5 variant than the March 2022 Spanish possession and identification reports.
