Unusual happenings with inactive US radio stations, signaling something big about to happen?

On SKYKING (8992 or 11175 kHz USB) a call sign called "COLLAPSE" which has not been heard since 2001 has just broadcasted 4 messages to numbered stations/units in the last few minutes.

"FUXEBOX" and "Reykjavik," have also broadcast in the last few days and they haven't been heard since 1991 (collapse of the Soviet Union).

"COLLAPSE" has sent 3 messages in the last few minutes.

Collapse message Two: http://vocaroo.com/i/s1ETZ3l9fp0G

Collapse message Three: http://vocaroo.com/i/s03ZI6ui70LY

Message Four from "FLATTOP!" (ANOTHER STATION NOT HEARD IN YEARS!): http://vocaroo.com/i/s01smhgkyNDL

We do not know what these codes mean, but it considered

These are alerts to "All Stations" before the codes are sent. I did my best to record all these but missed recording "the alert phrase" where they said "All stations, all stations." This has all happened in the last half hour (0230-0304 EST).
