Remember? they switched Security Clearances to DOD

5. DOD has always controlled clearances dealing with DOD information

Each executive department controls access to their own information. As an example, Department of Energy has its own clearance sturcture. I once held a Q clearance (sort of equivalent to a DOD TS), even though I held a TS with compartmented and codeword accesses, I was not permitted to access DOE classified information until I received the Q.
