The clearest public evidence for 9M119 Refleks-family missiles in the 2014 Russia-Ukraine War is captured materiel from the September 2022 Kharkiv counteroffensive. Defence24 reported on September 19, 2022 that Ukrainian troops had captured and found 9M119 Refleks-family tank guided missiles among Russian equipment and ammunition, and it embedded two open-source posts from the same period: OSINTtechnical's report of a cache of 125 mm 3UBK20 / 9M119M Refleks ATGMs captured in Kharkiv Oblast, and Ukraine Weapons Tracker's report of 30 9M119 Refleks missiles with charges left by the Russian army.
That evidence supports Russian possession and Ukrainian capture of the missile family in the conflict. It does not by itself confirm that either side fired a 9M119-series missile in a documented engagement.

Timeline
The documented capture cases occurred during Ukraine's rapid September 2022 gains in Kharkiv Oblast. ISW's September 16 assessment described Ukrainian forces taking the eastern part of Kupiansk and continuing operations east of the Oskil River, giving the campaign context for abandoned or captured Russian equipment in the region.
Ukraine Weapons Tracker posted on September 16 that 30 9M119 Refleks missiles and associated charges had been left by Russian forces in Kharkiv Oblast. OSINTtechnical followed on September 18 with imagery described as 125 mm cannon-launched 3UBK20 / 9M119M Refleks ATGMs captured by Ukrainian forces in the same oblast, and Defence24 summarized those captures the next day.

Narrative
The 9M119 Refleks / Svir family is a laser-guided, gun-launched anti-tank missile family for 125 mm tank guns. Army Recognition describes 3UBK20 Invar as a separate-loading 125 mm round carrying the 9M119M missile and lists T-72B, T-80U, and T-90S tanks as intended firing platforms.
In the Ukraine evidence, the missile appears as ammunition rather than as a separately recorded launch platform. The Kharkiv captures therefore matter for the catalog as battlefield availability: Russian forces had 9M119-series tank-launched missiles in the theater, and Ukrainian forces obtained at least some examples during the counteroffensive. Defence24 noted that compatible Ukrainian or captured tanks could potentially use the missiles, but the cited public material did not document a specific shot, target, or firing unit.
