Um, no. It is the DoE equivalent of the DoD's TS/SCI, nothing more. Public information, anon.
No. Non-military still get regular DoD clearances. Q clearance is literally just the clearance the DoE uses. They stayed separate from
the DoD when all of the other agencies combined their accesses
back in the early 2000s (not sure of the exact date).
This stuff is on Wikipedia, folks. Do some research.
Sigh, so some fucking research. It is equivalent to the TS/SCI the
DoD offers. Jesus you people are stupid.
