Direct proof of use
A 2025 Finnish National Defence University study of Ukrainian Armed Forces counter-UAS systems in the 2014 Russia-Ukraine War lists Piranha HAD-5 Omni among the electronic C-UAS systems identified for Ukrainian use in 2022-2024. The same study frames its research question around systems used by Ukraine's armed forces against the drone threat after Russia's full-scale invasion on February 24, 2022.
Piranha Tech's own HAD-5 Omni material identifies the device as a mobile backpack system for countering unmanned aircraft through radio jamming, with selectable bands, up to five simultaneous channels, and backpack power. The public record supports fielding as a Ukrainian counter-UAV electronic-warfare system; it does not identify a specific combat incident or named Ukrainian unit operating the Omni configuration.

Timeline
Piranha Tech says its electronic-warfare development work began in 2014 and that production moved to Drohobych in April 2022 after the full-scale invasion. By 2024, Ukrainian municipal support reporting separately described mobile portable PIRANHA 5 HAD complexes being supplied to military unit A6175, showing wartime supply of the broader HAD-5 line to Ukrainian forces.
The clearest public identification of the Omni configuration appears in the Finnish National Defence University study published in March 2025, which lists Piranha HAD-5 Omni in its table of hand-operated electronic C-UAS systems used by Ukrainian Armed Forces in 2022-2024.

Narrative
HAD-5 Omni belongs to the portable electronic counter-UAV part of the Ukrainian battlefield equipment record. The manufacturer presents it as a backpack signal suppressor intended to interfere with UAV control, video, navigation, and telemetry links, rather than as a kinetic air-defense weapon.
In conflict-use terms, the documented role is local force protection and short-range electronic air defense against drones. The available sources establish Ukrainian use or fielding of the system class and Omni configuration, but they do not provide a verified engagement-by-engagement record, loss record, or measurable battlefield effect for HAD-5 Omni.
