South Korea's Ministry of Defense: North Korea has provided Russia with more than 200 long-range artillery pieces

South Korea's Ministry of National Defense estimated that "North Korea has provided more than 200 long-range artillery pieces to Russia," according to a report submitted to the National Assembly's Defense Committee on the 11th.
"After sending troops to the Ukraine war, North Korea continues to provide support to Russia, including weapons and ammunition," the source said. According to the document, the scale of North Korea's support to Russia is 11,000 troops.
It is believed that there may be further support for troops, weapons, and ammunition in the future, including over 200 personnel, over 200 long-range artillery, missiles, and a considerable amount of ammunition.
Last November, South Korean Presidential Office Chief of National Security Shin Won-sik mentioned North Korea's support for Russia's "long-range artillery" for the first time, saying, "160 guns."
That's all," but it appears that further support was provided afterwards.
