Russian soldiers have been filmed training North Korean troops and giving them instructions on warfare.
In the video released, a small group of soldiers from Pyongyang are preparing to head towards the front line.
They are being taught how to lay landmines by Russian military instructors.
However, the training is interrupted when the North Koreans, who are wearing Russian uniforms, appear to have no idea what they are supposed to do, according to The Telegraph.
In a separate video from October, a Russian soldier is filmed trying to befriend a North Korean, only to be roughly pushed away.
Last month, a South Korean intelligence official revealed that Russia had been teaching North Korean soldiers about 100 basic military terms, such as “turn to your position,” “fire,” and “go.”
In a phone call intercepted by Ukrainian intelligence in October, Russian soldiers were heard saying there would be enough translators for the foreign troops under their command.
