I've been trying to find out whether the breach of background investigation info also includes military. I underwent an FBI background check in the 90's, and if there are 21 million records stolen, I have a feeling mine could be one of them. The paperwork I had to fill out pretty much told my life story, and I had to give names and addresses and phone numbers of people I knew. Which the FBI didn't talk to, they asked for others that knew me from those 5. Hell they even interviewed my high school counselor.
Regardless I am not feeling worried. What would the Chinese want with me nowadays?
