The introduction differs both visually and in terms of content. In the HK version, the backstory and character motivations are briefly outlined in a relatively neutral fashion (Note: the following quote retains the original subtitles' punctuation and grammar):
"Golden Triangle lies in the delta area amidst Burma, Combodia and Thailand Where produces 75% of world's drug February this year the Thai government determining To destroy it and its tycoon Samton Sent out a recruited troop Which was made up of several Chineses Some join for idealism Some join for return of a U.S. green card Some join to escape from family And some for money They all gathered here to kill"

In stark contrast, the Korean version dishes out some heavy-handed propaganda right off the bat (Please note that this is a machine translation of the opening crawl and as such may contain errors):
"After the red invaders of the Viet Minh Army had occupied the mountains of free Vietnam, an organization emerged which provided more than half of the world's drug supply through opium cultivation in the Golden Triangle, on the border between Thailand, Laos and Vietnam. It's name was 'Black Division'. Another organization led by Korean Jin Ho-geol, who fought alongside the whites as a warrior in Vietnam. He had lost his beloved wife to the Viet Cong and took his five-year-old son to the Thai border. One day, Jin Ho-geol, victorious against the cruel North Vietnamese army, received a secret assignment from INTERPOL: to capture Samton, the leader of Black Division, alive and transport him."

We're now treated to the first reshot scene in the Hong Kong version: An incredibly stupid bit of "comedy", culminating in the hi-larious punch line that Chin is eating human flesh. "I just killed a black soldier and cut off the butt of the corpse." In the English dub, this has been toned down and by simply turning it into into 3-weeks-old rotten meat. [The "black soldier" probably refers to one of Samton's people, but the old Engrish subtitles of the Hong Kong version leave some room for interpretation here]
