⚡️A North Korean M-1989 Koksan 170mm self-propelled howitzer, seen here on the Kursk front, was used to counter Russia's Ukrainian invasion. It is estimated that at least 100 Koksan howitzers were delivered by Kim Jong-un to Vladimir Putin. With mounting losses, Putin is being forced to turn increasingly to Iran and especially North Korea, which is providing arms and ammunition as well as troops to support his invasion of Ukraine.
