Open-source loss documentation records MT-LBu-family vehicles in service with both Russia and Ukraine during the full-scale phase of the 2014 Russia-Ukraine War. Oryx lists Russian MT-LBu-based specialist systems, including R-381T2M Taran-M radio-monitoring vehicles, and separately lists Ukrainian MT-LBu losses and an MT-LBu fitted with a BM-7 Parus combat module.
A dated field report from September 2022 gives a specific Russian example: Ukrainian forces captured an R-381T2M vehicle from the Taran-M signals-intelligence system in Kharkiv Oblast after Russian forces withdrew from the area. The report identifies the Taran family as MT-LBu-based and describes it as a Russian battlefield signals-intelligence asset.
Ukrainian use includes both baseline MT-LBu vehicles and battlefield conversions. Army Recognition reported in September 2023 that Ukrainian forces had shown an MT-LBu adapted as an infantry fighting vehicle with a BM-7 Parus remote weapon station; the same report cautioned that the observed firing event was not confirmed as either a test or combat mission.

Timeline
The MT-LBu's conflict record is clearest after Russia's February 2022 full-scale invasion. By September 2022, Ukrainian forces had captured a Russian R-381T2M Taran-M radio-monitoring vehicle in Kharkiv Oblast, tying the chassis to Russian electronic-warfare and signals-intelligence use in the theater.
In 2023, Ukrainian MT-LBu conversions with the BM-7 Parus remote weapon station were publicly documented. Later loss-list entries showed Ukrainian MT-LBu vehicles and at least one MT-LBu with BM-7 Parus among visually documented losses, indicating that the chassis was not only held in inventory but appeared in wartime service.

Operational role
The MT-LBu was not one single battlefield weapon in this conflict. Its importance came from the hull's role as a larger MT-LB-family platform for specialist equipment, command bodies, electronic-warfare systems, and improvised combat vehicles.
On the Russian side, the clearest documented function is specialist electronic-warfare and signals-intelligence support. The captured R-381T2M Taran-M example was part of a system used to monitor radio emissions and help locate emitters, while Oryx records additional Russian Taran-M radio-monitoring vehicle losses.
On the Ukrainian side, the documented uses include tracked mobility and fire-support conversions. Oryx records Ukrainian MT-LBu losses and a Ukrainian MT-LBu with BM-7 Parus, while Army Recognition describes the Parus-equipped vehicle as a modified infantry-fighting-vehicle configuration carrying a remote weapon station with a 30 mm cannon, machine gun, grenade launcher, and optional anti-tank missiles depending on fit.
