Direct proof of use
The Kozak-5 is documented in Ukrainian service during the 2014 Russia-Ukraine War through the April 2024 transfer of armored vehicles to the 225th Separate Assault Battalion. ArmyInform, the Ukrainian military information agency, reported that Defense Minister Rustem Umerov and Chief of the General Staff Anatolii Barhylevych handed the battalion 40 domestically produced Kozak armored vehicles, including 25 Kozak-5 vehicles built by Practika.
Defense Express reported the same handover and identified the recipient as fighters of the 225th Separate Assault Battalion of the Armed Forces of Ukraine. Its account described the package as 15 Kozak-2M1 and 25 Kozak-5 armored vehicles and framed the transfer as a move from sporadic Armed Forces use toward larger Kozak-5 deliveries.

Timeline
Before the April 2024 handover, Defense Express reported that Kozak-5 vehicles had strengthened Ukrainian security structures such as the National Guard and Border Guards before the full-scale invasion and had also been observed in some Armed Forces units, including the 25th Separate Airborne Sicheslav Brigade in 2023.
On April 24, 2024, ArmyInform reported the handover of Kozak armored vehicles to the 225th Separate Assault Battalion. On April 25, 2024, Defense Express followed with English-language coverage that specified the Kozak-5 quantity, recipient unit, and core vehicle details.

Narrative
In this conflict record, the Kozak-5 is best described as a protected mobility and force-protection vehicle for Ukrainian forces rather than as a weapon system with a documented firing role. SpetsTechnoExport markets the Kozak-5 as a Ford F-550-based armored vehicle for police and special forces, while Defense Express described the April 2024 Ukrainian Armed Forces batch as a five-seat armored vehicle with STANAG 4569 Level 2 protection, a reinforced chassis, upgraded brakes and suspension components, a 6.7-liter diesel engine, and a 10-speed automatic transmission.
The available public sources support fielding and transfer to Ukrainian units in the war, including the 225th Separate Assault Battalion. They do not, in the cited coverage, document a specific engagement, route, or tactical action in which a Kozak-5 was used; the conflict-use claim therefore rests on source-backed Ukrainian unit delivery and observed service rather than on a named battlefield incident.
