Nice list, if a bit basic.
It can go really deep, and several pages long if you go into subsets, nested subsets, and "special circumstances".
It's no wonder the agencies can't find their ***** with both hands when you get into the complexity of security
clearances---agency-department-project-project department-project departmentalisation subset working groups-etc ad infatum.
Not to mention supervisory compartments needing specific communication authorisation within,around and through, and "special curcumstances" where
one needs a one off bit from another subset of working group.
I'll bet the authorisation for some bits of a supposed reverse engineering program from 1945 are just being delivered to the requesters 25 years
after they died.
