North Korean troops fighting for Russia have been pulled from the front line for extra training after crude tactics led to massive casualties.

North Korea sent its best troops to aid Russia in its war against Ukraine. But after months of suffering severe losses, they have been taken off the front line.

The spokesman did not say how long that front line was. And while this is not the full picture, it does suggest significant North Korean casualties. Separately, the New York Times also reported that the North Koreans had been pulled off the front lines.
