I didn't get all 6 class medals. I think I got long ranger, but that's it. I got into the live thing late though. The medals can only be unlocked via online play, so it sucks now :( "Only veterans can handle this kind of language" is unlocked by beating the Single Player. It doesn't make single player mode uncensored sadly, but it makes all multiplayer things that are bleeped out uncensored. I uploaded a trailer a long time ago for a Chapter X walkthrough... Sadly I never finished it due to live being shut down and a general disinterest in it. Plus I don't have an xbox anymore, so I can't record it.
