The M-16 and tank bit is HILARIOUS! I get a sense of it as a comedy skit would play out. "Did you hear something? Hrm... I can't seem to back up!"
A bit excessive on the slo-mo, but overall a really good set of clips to decent music.

EDIT: I would say it's a big shame you've got your terrain graphics set to bare minimum, though. For such nice footage it's kinda ugly. Eye-candy-wise, I mean.
