the last 2 folders is Death and Damage (DoW files),
That would be a violation of the EULA of Dawn of War and Illegal in so many ways. The big problem now is that you have cast doubt on the legality of the other sounds you have presented.
Unless you can provide proof you made them yourself it is doubtful that we would use them.
The scout is an option for the expansion of the Ultramarines class structure, although as of right now its position is unknown (i.e. how would it work as a class) so i would not hold your breath on that one, certainly not in release 1, but maybe later.
*EDIT* please see this post as to what constitutes IP infringement.
