I saw this one on the wire earlier. Video games, like movies, books, and other media, have a narrative element as well as relationships with "real life," add in an interest in the players to play through scenes that are relevant to them and you have a case for going to the military to get the best you can get.
This means that once and a while something otherwise unknown to the public at large might find its way into a video game. It's not often that you end up seeing the investigation to public when it happens to be confidential information, but it seems to me that video games would be the first source of that.
Although, if it were a Tom Clancy book, chances are we wouldn't be posting about it on a video game site.
