Soviet 124th MRD

Most of the heavy lifting in Twilight War Korea would be done by the ROK military, which fields a large conventional force that is pretty solid by developed world standards. It's a sideshow for the US and anyone else who shows up but it's the South Koreans central concern. US forces in theater look the way they do probably because they're not getting support from CONUS and can't locally recruit like units in Europe. Being almost entirely reserve formations probably doesn't help either.
