Milcom monitors like Special Use Airspace (SUA)!
And the reason is you will find concentrated milair activity in and around SUAs. Special use airspace consists of airspace of defined dimensions identified by an area on the surface of the earth wherein activities must be confined because of their nature, or wherein limitations are imposed upon aircraft operations that are not a part of those activities, or both.
Restricted areas, Prohibited areas, MOAs, Alert Areas, Warning Areas, and National Security Areas are covered in a publication that is issues yearly by the FAA. PDF document FAA Order JO 7400.8N dated 16 Feb 2007 is a free download at
