When I reclassed to signal, I had to obtain a TS-SCI/SSBI. They talked to my parents, friends, teachers, hell, anyone that dropped a name, they talked to that person. They had information on me that I couldn't even recall. They checked my credit, arrest record, MVR, and everything else. It's called national security......but then again, the DUmmies aren't concerned with national security, are they?
