There are missions for which an assault rifle is too much a handgun is too little. Close quarter combat, law enforcement tasks, personal protection: these are the situations where submachine guns excel, trading in range for a high rate of fire and ease of use by soldiers.
Soldiers often do not travel inside armoured vehicles or on lorries, but, if the mission and safety situation allow, in comfortable conditions, by bus. This passenger transport capability has been known to the armies since the First World War, and the Hungarian vehicle industry has long been able to cover this area by delivering various Ikarus buses. However, the well-known and popular Hungarian buses had been obsolete by the early 2010s, so a decision was made on the development of a new, already multi-purpose type.
The modern BREN 2 assault rifle can be seen in the hands of more and more Hungarian infantry soldiers. It quickly became a popular weapon thanks to its modern, modular design, lower weight, and high accuracy with its optical aiming system.
