Direct proof of use
The documented Russia-Ukraine War link for the TS-50 entry is the Iranian YM-1 copy rather than an identified Italian-made TS-50 stock. The Sappers YM-1 handbook describes the YM-1 as an Iranian-manufactured TS-50 anti-personnel blast mine and says mines procured by the Syrian Ministry of Defense began moving to DPR and LPR forces through the Russian Federation in November 2017.
That evidence supports supply and fielding by Russian-backed forces in the Donbas phase of the conflict. It does not, by itself, identify an exact minefield, detonation incident, or Italian-produced TS-50 example in Ukraine.

Timeline
The technical background predates the Ukraine evidence. The IMAS technical note states that the Iranian YM-1 is a copy of the Tecnovar TS-50 anti-personnel mine, and its July 2013 amendment identified the YM-1(B) as a related variant encountered by mine-action organizations.
The conflict-specific milestone is November 2017, when the Sappers handbook says Syrian-procured YM-1 mines began being supplied to the DPR and LPR through Russia. The available public source describes regular deliveries but does not provide shipment quantities or specific receiving units.

Battlefield role
In this conflict record, the YM-1/TS-50 branch is best described as anti-personnel area denial. The Sappers handbook classifies YM-1 as a pressure-operated anti-personnel blast mine with a plastic body, pressure initiation, and low metal content, characteristics consistent with a mine intended to remain hazardous until triggered or cleared.
Broader mine-action sources describe Ukraine as heavily contaminated by mines and explosive remnants during the ongoing war, but those sources do not independently identify YM-1 or TS-50 use. They provide context for the hazard environment only; the direct weapon-specific claim remains the Sappers handbook's report of YM-1 supply to DPR and LPR forces through Russia.
