Vigilant guard eh?
9/11/2001 has a few:
The military exercises (war games) planned for September 11, 2001, included:
Global Guardian, an annual command-level exercise organized by United States Strategic Command in cooperation with Space Command and NORAD. Primary purpose is to test and validate nuclear command and control and execution procedures. Global Guardian is performed in conjunction with NORAD's Vigilant Guardian and Amalgam Warrior, as well as exercises sponsored by Air Combat Command (Crown Vigilance) and Space Command (Apollo Guardian).[3][4]
Vigilant Guardian, the semiannual NORAD exercise that had been running in conjunction with Global Guardian for several days and which postulated a bomber attack from the former Soviet Union. Vigilant Guardian is a Command Post Exercise (CPX), meaning it is conducted in offices and with computers, but without actual planes in the air. The exercise involves all NORAD command levels.[5] Out of a range of scenarios being run on September 11, 2001, one was a "traditional" simulated hijacking.[6] According to General Eberhart, after the first attack, "it took about 30 seconds" to make the adjustment to the real-world situation.[7] Because of an increased number of staff, the exercise would prove to be an enabler of rapid military response for NORAD and its NEADS component, as senior officials who were manning NORAD command centers throughout the U.S. were available to make rapid decisions.[8]
Vigilant Warrior. In his book Against All Enemies, Richard Clarke recounts that there was a NORAD exercise ongoing called Vigilant Warrior.[9] The claim is based on a comment that Richard Myers made to Clarke via a video link on September 11, 2001. However, there is no other record of a NORAD exercise named Vigiliant Warrior. Myers was possibly referring to Vigilant Guardian (the aforementioned yearly NORAD exercise held in conjunction with Global Guardian) or Amalgam Warrior (a large-scale, live-fly, CINCNORAD sponsored exercise which is held twice annually).[10] Vigilant Warrior was also a 1994 operation by the US army in the Persian Gulf region, in response to Iraqi troop movements towards Kuwait.[11]
