Open reporting documented the RPG-27 Tavolga in the Donbas phase of the 2014 Russia-Ukraine War. Censor.NET, citing Ukraine's ATO press center, reported on 14 August 2016 that militants fired RPG-27 Tavolga anti-tank grenade launchers at the pedestrian bridge in Stanytsia Luhanska, Luhansk region, and that Ukrainian soldiers found shell remnants near the bridge.
UNIAN reported on 11 August 2017 that RPG-27 Tavolga launchers had been used against Ukrainian positions in Donbas, including a Ukrainian soldier's account that his company's positions came under fire and two soldiers were wounded. Business Insider separately summarized 112.ua reporting that Russian-backed separatists used an RPG-27 Tavolga against Ukrainian troops in a front-line village in Luhansk region.

Timeline
The first specific public incident in this record is the 14 August 2016 Censor.NET report on Stanytsia Luhanska bridge shelling. The report identified the weapon as the RPG-27 Tavolga, attributed the firing to militants, and said remnants were found near the bridge.
A second dated cluster appeared in August 2017, when UNIAN and Business Insider reported RPG-27 use against Ukrainian positions in the Luhansk-front context. Both accounts framed the launcher as a Russian-origin system not in Ukrainian army service.

Narrative
In the documented Donbas cases, the RPG-27 appeared as a short-range infantry anti-armor and assault weapon rather than as a mass battlefield system. The cited incidents place it with Russian-backed forces or militants on the Luhansk front and describe use against fixed Ukrainian positions or infrastructure around the contact line.
The sourcing does not establish a complete inventory, transfer route, or number of RPG-27 launchers in the theater. It does support the narrower claim that RPG-27 Tavolga launchers were fired in the conflict by Russian-backed forces and that Ukrainian-side reporting treated the weapon's appearance as evidence of Russian-origin materiel in Donbas.
