I can't find anything anywhere, does anyone know were I may find it (if any)?

Well, the first part of the openig about "15 years ago, there was a war..." and when wardog squadron engages the unidentified airplanes and when Barlett is talking to the squadron in the crew ready room... they are all in the AC5 OST Disc 4
You can download them from the Galbadia Hotel or there is already a thread about this where you can download all the AC series soundtracks:

Ok, thanks, but I was referring to the movie before you push start to play the game (the part with the medley of liens from the game, but without anyone talking).

You mean "Blurry" by Puddle of Mud? I haven't seen a karaoke or offvocal version of it before.

No, I have that, I just need the opening movie version (the cut version) (oh right! I have First Flight (or whatever it's called) and I need that Razgriz one too).

ok so you want the opening/trailer song
It is called "The Unsung War": CD3 track 13
It is the longest version but it is not in the same order as in the trailer but it is the same song.
And Razgriz, well...
CD2 track 3 Demons Of Razgriz
CD3 track 15 Razgriz
CD4 track 17 Razgriz ''ACE COMBAT 5 Main Theme''
You will have to listen to each one of them to know which song you want.

Why would you want the cut version of the song? All it is is the intro to the song that fades directly into the chorus.

The reasoning for this is that they didn't want to pay the full price to lisense the song from PoM, which is why throughout the game you keep hearing the same lines of the song over and over again.

The best things about that song are the full lyrics and the verses. And the funny thing is that the song in it's entirety would fit the game very well but without them, IMHO, the song doesn't carry a lot of weight. Nor, IMHO, should they have even tried to include it if they were going to butcher it like that.

I need it for something, but it looks like I'm going to have to do it myself...
