The consolidation of the Air Defense Sectors has been going on for about 20 years now. You may remember when they consolidated the NW and SW into WADS at McCord around 1990 I think. Well they were supposed to do the same thing in the East, but never quite got around to it completely. The Eastern half maintained two operational centers in Rome (Griffiss) and Pensecola (Tyndall) with a joint command located at Tyndall. The operational centers have since been consolidated to the Rome location, the Command is in the process of moving, They are building an new administrative building next to the Ops center. This isnt anything classified, a google search and some time reading will tell you everythign you want to know.
While Huntress is used in the US, FOOTROPE is still used in Canada. Canada does operate out Rome also. There is a fairly significant contingent of Candian Air Forces in Rome. If you hang out in the right bars you can find them with their wierd cigarette packs. And of course if they are in their duties, the maple leaf kinda stands out at McDonalds or the grocery stores.
And yes security is a little touchy, there are quite a few assests those security forces protect. Just imagine them durring woodstock!
