Blue and 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 cross, an international symbol of medical care, symbolizes the Squadron's primary mission. The eagle reflects the national defense mission of the Air Force. The pillars signify readiness, Tricare deployment, size management, and preventative health care, the four functions of the Surgeon General's military health care system, which the unit supports.
