The C90-CR-AM (M3.5) is documented in the 2014 Russia-Ukraine War through open-source imagery reporting from the first month of Russia's full-scale invasion. Militant Wire cited War Noir's March 15, 2022 identification of a Ukrainian Azov Battalion combatant video showing a 2022-dated RPG-75-M, an Instalaza C90-CR-AM M3.5 from Spain, and a Swedish Pansarskott m/86 AT4 among newly supplied anti-tank weapons.
Soldat & Technik's March 2022 roundup of infantry anti-tank weapons in Ukraine reproduced the same War Noir identification and placed it in a survey of single-use anti-tank weapons documented with Ukrainian forces. These sources support the AM M3.5 variant appearing in Ukrainian hands during the war; they do not, by themselves, confirm that this specific C90-CR-AM was fired, which target it was assigned to, or whether it produced battlefield damage.

Timeline
Spain publicly moved to send anti-tank grenade launchers, ammunition, and light machine guns to Ukraine at the start of March 2022. Reuters reporting of Spanish defense minister Margarita Robles' announcement described a first shipment of 1,370 anti-tank grenade launchers and 700,000 rifle and machine-gun rounds, with delivery by Spanish air force aircraft to Poland for Ukrainian pickup.
By March 15, 2022, open-source imagery accounts had identified the C90-CR-AM M3.5 specifically in a Ukrainian combatant video. Later reporting and catalog entries often discuss the broader C90 family in Ukraine, but the AM-specific claim used here rests on sources that identify the C90-CR-AM M3.5 by variant.

Role in Ukrainian service
The documented role was infantry-portable anti-armour and fragmentation capability within Ukraine's early foreign-supplied light anti-tank inventory. Instalaza describes the C90-CR (M3.5) as a disposable 90 mm shoulder-launched weapon system, and lists the C90-CR-AM (M3.5) load as dual-purpose, combining anti-armour and fragmentation effects.
The available conflict evidence is observation-based. It establishes that an AM M3.5 was visible among newly supplied weapons with Ukrainian combatants, consistent with Spain's broader transfer of anti-tank grenade launchers to Ukraine, but it does not establish quantities of the AM load, allocation beyond the observed unit context, or a verified combat engagement using this exact munition.
