   The Berest is a recent Ukrainian artillery rocket system. Its official designation is BM-21UM. It can be seen as a further development of the Ukrainian BM-21U. Essentially it is a modernized version of the venerable BM-21 Grad. The Berest was first publicly revealed in 2018. However by late 2020 there were no production orders for this system. Most likely that it will become another Ukrainian weapon system that could not reach production due to corruption and funding problems.

   The Berest has 50 launch tubes, instead of 40 of the BM-21U and the Grad. The new Ukrainian artillery system is based on a KrAZ-5401NE truck chassis. This truck was specially designed for heavy duty applications. This artillery system also uses new navigation and targeting systems.

   These rocket systems proved to be extremely effective against area targets.

   The Berest is compatible with all rockets, developed for the BM-21 Grad, as well as newly-developed rockets. A standard 122 mm HE-FRAG rocket weights 66 kg and has a range of around 20 km. Maximum range of fire is up to 40 km with extended-range rockets. At a maximum range of 40 km rockets have a CEP of only 90 m.

   The Berest is operated by a crew of 5. Vehicle has a double cab which accommodates all crew members. The cab is actually of Chinese origin. Similar cabs are used on Shaanxi high mobility tactical trucks, such as the SX2300. Also this cab strongly resembles those of the the German MAN military trucks. Windows are positioned vertically in order to reduce light reflections.

   The KrAZ-5401NE is powered by an unspecified diesel engine. Most likely that it is a Russian YaMZ-238D diesel with 330 hp. This engine is common on KrAZ military trucks. It is likely that the engine was not specified exactly due to hostile relations with Russia. The KrAZ also offered Cummins, Deutz, Volvo and other Western engines on its vehicles. Vehicle is fitted with a central tyre inflation system, which improves mobility over difficult terrain.

   The new KrAZ-5401NE truck is less expensive to produce and to operate than the KrAZ-6322 truck of the BM-21U, or the Ural-375D and Ural-4320 military trucks of the BM-21 Grad. However the new KrAZ-5401NE truck with its 4x4 configuration looses in terms of off-road mobility to the above mentioned trucks with 6x6 configurations. Though developers of the Berest state that depending on customer requirements other chassis can be used.

   In combat other this artillery rocket system would be supported by an resupply truck, which would carry reload rockets. Reloading of these artillery systems usually takes place remotely from firing positions in order to improve their survivability against counter-battery fire and attack drones. The crew can reload this rocket system within 10-15 minutes.

   A battery of such rocket systems also includes command vehicle.
