According to multiple sources sharing it, this photo of a North Korean M1989 ‘Koksan’ self-propelled howitzer was taken on Russian territory, on a freight train heading to Ukraine. If this is true, it means that Putin is receiving howitzers and possibly armored vehicles from North Korea in addition to North Korean soldiers and machine guns. This could be an indication that Russia is facing logistical difficulties in replacing its losses on the front line, and is therefore forced to turn to North Korea.
