In the early '80s, after South Korea's most popular dictator Park Junghee was assassinated by one of his closest friends, power was seized by the man who would become Korea's worst dictator, Chun Doohwan. Chun created Samchung Re-Education Center, a place where he sent gangsters, homeless, the undereducated, the overeducated, leftists--basically anyone he considered an enemy of the state. Apparently 60 000 people were arrested, and over 3000 died there. Certainly not as bad as what was going on in North Korea, Cambodia, Indonesia, etc, but remember that South Korea wasn't above prison camps as recently as the 1980s.
Having a band named Samchung around certainly raises awareness of this dark page in South Korean history. On the other hand, Samchung is basically a far-right band that seems to support Korea's pre-democracy regimes. I've never gotten a straight answer out of them on why they chose that name.
Samchung is probably the senior skinhead band of the scene, although they're not really identifiable as skinheads. The lead singer, Donghyuk, had to grow his hair out, apparently when he got a job at a pizza parlour--I'm guessing so that the hairnet would fit.
The bassist, Boram, still keeps his head shaved, and I'm sure he's still got that belly tattoo.
I'm not exactly sure how the doo-rags came in, but it seems they're copying similar nationalist bands in Japan. These guys are into all kinds of nationalism, having covered "Tomorrow Belongs to Me" by Skrewdriver. Also, Boram, the tattooed bassist shown above, swears he saw Pluton Svea play live when he was in Sweden.
As these guys have drifted more and more towards metal, they've brought pretty well the whole skinhead scene with them. It's their influence that turned Captain Bootbois away from oi and toward metal. Also the skinheads who don't follow along with them get left behind.
Here you can download a mix of Samchung songs from three stages in their 12-year career. The earliest song is "Rest in Peace," off an old compilation where you'd swear they're Agnostic Front. Next up are two songs from their album "Way of Men" (in which their session drummer was a woman). And it's finished up with the most recent songs, their half of a Samchung/Captain Bootbois split.
