Ultramarine blue and Air Force yellow are the Air Force colors. Blue alludes to the sky, the primary theater of Air Force operations. Yellow refers to the sun and the excellence required of Air Force personnel. The mountain range represents the steep odds the unit faces in defending and protecting the United States and its citizens. The star with red tips simulates a sheriff's badge and symbolizes the unit members' role of law enforcement, much as it was in the old West. The unit is represented by people of moral authority who fight for the greater good. The Big Dipper and North Star are guides for mariners, symbolizing the guiding principles leading the future of air and space supremacy. The motto, "ETERNALLY VIGILANT," defines the unit mission of defense and security without end--alert and always ready to respond.
