Direct proof of use
The MT-LB-12 is documented in the 2014 Russia-Ukraine War through Ukrainian military media and follow-on defense reporting on local conversions. On 13 August 2022, ArmyInform described Ukrainian soldiers demonstrating a captured-equipment vehicle that combined an MT-LB armored tractor with an MT-12 Rapira anti-tank gun, calling it a self-propelled anti-tank artillery installation and reporting that it had been tested and was already in the combat zone.
Defense Express identified the same Kraken-linked vehicle as an improvised self-propelled gun on a captured MT-LB chassis, with the MT-LB used as a tracked carriage for the MT-12 Rapira. The report emphasized the mobility gained by mounting the towed gun on a tracked vehicle, while noting unresolved issues around crew protection and ammunition placement.

Dated appearances
The first well-documented public appearance came in August 2022, when the Kraken-linked vehicle appeared in Ukrainian official and defense-media coverage. The Armourer's Bench reported that the footage was filmed in Mykolaiv region in early August and noted visible design features including rear stabilizing supports and a barrel travel lock.
A second public branch of the conversion appeared in late September 2022, when Defense Express reported that Ukrtransgaz had assembled an MT-LB and MT-12 Rapira combination after a local Territorial Defense unit request. The same report said the vehicle had completed required tests and would soon deploy near the Russian border, and also described earlier August examples linked to Kraken and the 59th Mechanized Brigade.

Role in Ukrainian service
The conversion turned a towed 100 mm anti-tank gun into a mobile direct-fire and fire-support vehicle. Army Recognition described the Ukrtransgaz vehicle as a mobile anti-tank armored vehicle and said the MT-LB chassis allowed quicker deployment and withdrawal from firing positions. This fits the reported Ukrainian need to reuse available Soviet equipment and captured vehicles during the full-scale war.
Public reporting does not show a standardized production vehicle. The available examples differ in crew layout, shielding, stabilizers, and whether the mounted gun is an MT-12 or a closely related older T-12. The clearest source-backed conflict role is therefore an improvised Ukrainian self-propelled anti-tank and support-fire platform rather than a formally standardized armored vehicle type.

Limits of the evidence
The public record supports fielding and combat-zone use, but it is thinner on named firing incidents, target effects, and unit-by-unit inventories. The best-supported claims are that Ukrainian personnel built and fielded MT-LB/MT-12 conversions, that at least one Kraken-linked vehicle was tested and in the combat zone by mid-August 2022, and that a later Ukrtransgaz-built vehicle was made for a Territorial Defense request after testing.
Later reporting described continued MT-LB-12 sightings and discussed direct and indirect fire roles, but some of that reporting relies on social-media imagery and should be treated as lower-confidence than the August and September 2022 Ukrainian and defense-media accounts.
