Very odd though, when you think about it.
No attribution to it (obvious link to TV shows or companies). Must've required expensive equipment to film, or else contained a small amount of CGI in certain places (bullets in flight). In one shot we see what appears to be a full-auto AR, but shortly thereafter we see what appears to be the same person (who is inexplicably wearing a mask on his face) with the same weapon firing semi-auto. And then there's the bikini girl at the end.
Where the heck did that video clip come from?
