[Age of Reason]

Hmong were regarded during the war as a kind of Asian Apache. They killed vietnamese because they were...different and they plain hated them.

And weren't those the tribesmen depicted in the movie Apocolypse Now--the guys who went around chopping off heads and putting them on sticks?

No wonder.

My personal experience was with the 'Mong. The Bodes had a tribe of something else, there were nomadic groups and may there have been a Thai group. Can't think of anything other than the Montagnards, which I THINK were depictwed in Apocalypse.
