I’ve been in a bunch of SCIFs but they were all downrange in centcomia and basically were tents or sections of a warehouse with a bored-looking dude with an m4 checking IDs and passes before letting people through a tent flap or plywood door. That is really only permitted under contingency ops rules and required treating the entire base as a perimeter, then a compound with itself higher security, etc. There was enough physical separation from likely threats that it was still mostly ok. Of course, people still had to be repeatedly counseled for plugging the same USB flash drives from personal movies/internet/etc systems into red (S) and orange (TS) systems. It was sad. Realistically security countermeasures adapt to the likely threats. In Iraq and Afghanistan the technical sophistication of the adversary in terms of SIGINT/ELINT was poor, so they rightly decided giving up security for wider distribution of information with friendly forces was the right call.
