I wonder what the North Koreans think of Russia. Like did they arrive and think, “what a shithole”? You know Kim can’t have them seeing anything decent or they will defect.
I am flabbergasted that Russia has training grounds. This is not a joke. I thought they just put you in a green overall, give you a 60 year old gun in one hand and a bottle of vodka in the other. And that’s it. Off you go!
I wonder if the language barrier will be an issue for these troops. Not sure how many norks speak Russian, but I’d imagine not many in the military would.
My guess is they will be compartmentalized to their own unit(s), with dual speakers coordinating with Russian units/leadership. Though, like you say, there probably aren't very many of those, so these units will be particularly at risk if their rare dual speaker gets taken out. They could probably mitigate this a bit by having dual speakers in safer locations one tier up the command chain.
This all assumes they will be in front-line roles. It is possible they will get assigned to safer duties, freeing up Russian soldiers to go to the front.
