Two things: One, if it goes boom, their job is to find it and lob it at the enemy, so with NK arms on the battlefield in the first place, this isn't really that surprising.
Two, the article mentions NK supplying clothing, and I couldn't help but remember that westerners and east asians tend to have a different build and stature. NK specifically suffers occasionally from famine, and malnutrition would further stunt growth. Where Russia produces an abundance of food in the fertile western parts of their gigantic landmass.
So, does that mean a bunch of Russian conscripts are running around in uniforms 2 sizes too small for them? lol
This would not prohibit them from having clothing stockpiles that they could contribute. The article said it, regardless. I'm not sure what they're basing the claim on.
