So far it's been no problem maintaing my TS/SCI. The interview goes ok, once I get the interviewer to pull his head out of his @$$ and try to understand that the Cold War has been over for 15yrs or more. Then I have to explain how it was possible to get the job (once he figures out that I had an Embassy tie in, it becomes much more clear).
This will be something for all folks to get use to as the bases eventually open in CZ and Poland, and the basing of C-17s in Hungary comes to fruition.
