Hmm... Thanks for the answer man, but actually it's not the right one.
The commercial I am thinking of is a kind of platform adventure/ trial. The marine has to run over a narrow bridge and fight a dragon...
I might be wrong with the claim I mentioned, but the ad is the one with the dragon.
> Is there someone out there who knows who did the music in the "Be one of the few. The Proud. The Marines." commercial?
