Direct proof of use
Ratel S entered the public record as a Ukrainian ground robot for the full-scale phase of the 2014 Russia-Ukraine War in October 2023, when Ukrainian military media cited Mykhailo Fedorov saying soldiers used it as a mobile warhead carrying anti-tank mines or a combat module. Defense Express reported the same fielding context and said the system had passed state tests and entered mass production.
Later reporting tied the system to specific battlefield incidents. LIGA.net and ArmyInform reported that Ukrainian defenders used Ratel S to blow up a bridge at Ivanivske in Donetsk Oblast in April 2024, while UNN reported that soldiers of the 25th Airborne Brigade used a Ratel S platform against an underground passage near Novohrodivka in September 2024.

Narrative
Ratel S appears in the war as part of Ukraine's rapid wartime expansion of remotely operated ground systems. The public descriptions emphasize a compact ground platform that can move an explosive payload or anti-tank mines toward a target while its operator remains at standoff distance.
Its documented tasks are narrower than general reconnaissance or logistics UGV use. The cited incidents describe attack and denial roles: carrying explosive payloads, threatening tanks or dugouts, attacking a bridge used for Russian logistics, and striking a covered Russian position near Novohrodivka. The manufacturer describes the current product as a remote-mining system, which is consistent with the reported mine-delivery role but does not by itself prove battlefield use.
The public record remains Ukrainian-source heavy. The strongest direct battlefield evidence for this page is the cluster of Ukrainian military, government-linked, and Ukrainian news reports that name Ratel S and connect it to specific front-line uses in Donetsk Oblast.
