Interesting numbers.
North Korea contributed:
* 15,000 troops
* up to 6.7 million artillery shells
* 1.24 million mortar shells
* 878,300 rockets for MLRS
* 248 KN-23/24 ballistic missiles
* 794 howitzers and launchers
Dude is advisor in Ukrainian government, so I assume they work with these numbers. How honest the report I dunno, but sounds plausible.

Other interesting part of the tweet:
>Russia mainly provides food, oil, limited air defense systems, GPS jammers, and possibly aircraft, with little other significant aid or foreign currency.
However as we noticed it here: >>52578 they also gained some other stuff. Not sure how serious their drone industry and palpable their capacity to carry out attacks with them, for the whole thing could be just propaganda.
The tweeter of this tweet has reason to twist the truth.
