Again, I think it's the other way around. Civilian aircraft have
access
by default even to areas that on maps are designated for military
operations. The military notifies the FAA when an actual operation
in such an area is scheduled so that a NOTAM can be issued.
But -- correct me if I'm wrong -- typically a TFR will not be issued.
