For starters, we don’t know how NK troops are trained but we can make some good guesses based on the terrain they would fight SK on and what weapons they are known to have. NK troops in Ukraine are going to be fighting in a completely different environment. (Oh. Their actual combat experience is basically nil.)

Ukraine has perfected drone warfare over the last few years. If they are spending between $200-$1000 per drone, there is absolutely no reason to use custom machined parts that might cost thousands. If an old RPG , a bare bones drone and a quarter roll of duct tape can take out a multi-million dollar bit of hardware, I would classify that as a bit of brilliance.

Sure. It was partly started because of cost and manpower constraints, but it’s so much more than hack hardware these days.
