Essentially, Steel Commanders is a song that is literally about tanks, which make sense. It’s obvious why the disable option would be there in case someone hates Sabaton for some reason. I wouldn’t be so mad if you wouldn’t be able to get it in the game for some otherworldly copyright reasons so you know, at least give a try.
OH and I forgot to say that the song was made cuz World of Tanks sponsored Sabaton.
