North Korea has handed over 1.5 million artillery shells to Russia, but half of them are either unusable or need at least a thorough inspection — The Times.

"As of today, given the available statistics, Russia has already imported 1.5 million rounds of ammunition from North Korea, but these shells were manufactured in the 70s and 80s. Half of them do not work, and the rest need to be either repaired or tested before use.

North Korea is giving away old things... North Korea is increasing domestic production and asking for certain technologies in exchange, particularly missile and submarine technologies, to develop its own defense industry. This proves once again that Russia lacks the production capacity to rapidly and strongly increase missile production.

If they didn't, why would they ask North Korea to do so?" says Vadym Skibitsky, a representative of the Ukrainian Main Directorate of Intelligence.
