CZ BREN 2 is a Czech modular assault-rifle family from Ceska zbrojovka, chambered across 5.56x45mm NATO, 7.62x39mm, and 7.62x51mm BR/DMR variants. Official Ukrainian and Colt CZ sources tie the rifle to Ukrainian Armed Forces battlefield deployment during the 2014 Russia-Ukraine War and to later licensed Ukrainian assembly under the Sich program.
Ukrainian official and military-linked sources document CZ BREN 2 rifles fielded by Ukrainian forces, including International Legion personnel, with later licensed Ukrainian assembly under the Sich program supporting Defence Forces supply.
Role detailsThe Ukrainian assembly program followed battlefield use rather than replacing it as the only public evidence. Ukrainian Defense Industry and Colt CZ both describe CZ BREN 2 deployment by the Ukrainian Armed Forces before the licensed assembly and technology-transfer steps.
