Based on this seriously groovy video whose origins I do not know: www.youtube.com/watch
One of my Deathwatch group made this video, which we know play whenever someone is rolling for Righteous Fury. Obviously, the music is silly, but hey, we have fun. The video was put together with clips from a cutscene from Dawn of War 2, bits of Space Marine promotional video, and clips from the Ultramarine movie.
You are, of course, welcome to use it if for some reason you are also a silly person.
