A Russian 170mm M1989 Koksan self-propelled howitzer, made in the DPRK, was filmed by one of the drones, west of Kremennaya. We have shown them before. Presumably, the M1989 Koksan self-propelled howitzer is used by the 73rd Artillery Brigade of the 25th Combined Arms Army of Russia. The M1989 self-propelled howitzer can fire rocket-propelled projectiles at a range of up to 60 km. Thanks to the M1989 self-propelled howitzer, Russian artillery units have expanded the range of ammunition used and increased the range of artillery.
