I think the civvies thing may have been pushed from higher than wing level, since more than one base in the AOR made the exact same change on the exact same day.
And another 10 feet prior to that. We've all seen it in every aspect of the Air Force. Taking CBTs for every ORE leading up to an ORI so you can be "more green", the OG/CC setting a time for a briefing, SQ/CC pushes that back 15 minutes, FLT/CCs push THAT back 15 minutes, soon you're sitting in the base theater an hour before the briefing is supposed to start, one crew does something stupid in a plane and we're all watching a video of the CFACC telling us not to dick around...
