Ukraine’s Unmanned Systems Forces (SBS) announced on 30 September that drone operators from the 412th Nemesis Regiment destroyed four North Korean-made Koksan self-propelled howitzers operated by Russian troops in southern and eastern Ukraine. One strike involved coordination with other Ukrainian Defense Forces units.
SBS published video of the operation on its official Telegram channel.
Ukrainian drone units strike Koksans in two oblasts
Drone pilots of the 412th Nemesis Regiment detected and eliminated the Koksan artillery systems in Luhansk and Zaporizhzhia oblasts.

The video shared by the Unmanned Systems Forces shows a drone spotting the first Koksan howitzer, followed by a munition drops directly onto the target.
The footage then captures more munition drops on three more howitzers, with a reconnaissance drone recording the impact from a distance, confirming the successful hits.
Soldiers from the Asgard battalion, part of the 412th Nemesis Regiment of SBS, later struck the fourth Koksan using a first-person-view drone. Reconnaissance drones recorded the impact from a distance.
