The music is heard in this video, like the bit from 0:37 onwards.

The name of the track is Chant, by Hans Zimmer from the Black Hawk Down soundtrack.

I've heard music similar to that for the GLA on Generals. What I want to know is, is there more like that, and where can I get hold of it?

Pirates of the Caribbean for Hanz Zimmer

I loved the black hawk down game :O

And then the film

I replayed the game so much i loved it!
