It shows that Russia has exceeded its own capacity for producing munitions and having to reach out of others for such a basic product. Further, reports from Russian soldiers using North Korean artillery shells report how poorly they’re constructed which makes them many times ineffective, but also dangerous to Russians firing them.
Performance is inconsistent from one shot to the next, which is horrible for something you have to fire again and again to zero in on your target. Other shells are simply exploding in barrels damaging Russian guns and wounding Russian operators.
I hope Russia switches exclusively to North Korean shells.
