We are Marshall

[musicin617]

Hi everyone, I have been searching for this piece of music for such a long time and thought maybe someone out there would know the name of this piece! It is at the beginning of this trailer (widescreen) and is instrumental. The theme repeats a few times but the voice over on the trailer makes it impossible to ID using Shazam. I tried midomi as well and couldn't find a match.

Here is the youtube link to the trailer:

Any guesses would be greatly appreciated! Thank you in advance!
