The faith no more song was actually playing on the speakers inside of the building the rangers were camped out in. It was playing on the speakers when they were loading up gear. I don't remember if it was the first time they went out, or the second time for the rescue mission. I just remember the "little bird" helicoptors getting fired up and ready to roll during it.
I haven't seen the movie since it was in the theaters so my memory is a little hazy about it.
