At first I thought you were talking about the former course at Youngsan Army Garrison - which was literally right in the middle of Seoul. I wouldn’t put it on my list of NLEs that I miss, but I did play Youngsan in 1986.
But having followed your link, I was not aware a course was constructed near Camp Humphreys.
March has changed in S. korea since I was based there in 1986. Lol.
They only had a driving range on Youngsan 10 years ago. The course in my link is NLE and was a course close to Youngsan. There is now a course, River Bend, on Humphreys that looks to have much less character (

Having the course on post makes a lot more sense from a morale, welfare and recreation perspective, with most people not being permitted to own a car and therefore the younger and more junior folks weren't able to access Sung Nam, but I really loved it.
There are a number of military courses I've played that are NLE.
