Direct proof of use
The KVERTUS AD G-6, also reported as the KVS G-6, is documented in Ukrainian service during the 2014 Russia-Ukraine War as a portable counter-UAV jammer. Business Insider reported in February 2023 that Ukrainian soldiers used the KVS G-6 to jam Russian drones, bring them down without destroying them, and recover data from the aircraft.
Earlier reporting from The Register identified the Antidron KVS G-6 as a Ukrainian-made Kvertus system that had emerged during Russia's full-scale invasion, and said many orders came from volunteer organizations, donors, and businesses buying devices for front-line military units. Unmanned Airspace separately reported that Kvertus had supplied more than 80 KVS G-6 long-range drone jammers to Ukrainian forces, with more than 100 additional units on order.

Narrative
The AD G-6's documented conflict role is defensive and electronic rather than kinetic. Business Insider described the system as using radio signals to jam Russian drones, while Kvertus's product page lists interference bands for remote-control, video-transmission, GPS, and Glonass links. The reported battlefield purpose was to disconnect or disable hostile UAVs so they could be brought down and examined.
The evidence supports Ukrainian use and supply, not a complete inventory or verified kill count. The clearest public claims are that Ukrainian soldiers used the KVS G-6 against Russian UAVs, that Kvertus supplied more than 80 devices to Ukrainian forces by early 2023, and that additional orders were reported. Defense Express adds later context for Kvertus's wartime counter-UAV development cycle and identifies the AD KVS G-6 in Ukrainian anti-drone-unit service from a Ukrainian Military TV frontline report.
