Here is a video montage of ROK SF training. There are some knife sparring sprinkled in here but mostly Koreans posing with guns and training.
Some scenes of the video are clearly staged. Like this guy who is clearly not aiming with anything.
The variety of weapons is surprising. I saw a few H&K guns like the MP7 and HK416. There were a lot of MP5s but it is hard to tell if they are H&K or some clone. I was surprised to not see the Daewoo K7 in this video.
It is a fun video to watch. Hope you enjoyed it as much as I did.
