This positional flag for the Chief of the National Guard Bureau was used from 1998 to 2008. The dark blue represented the Army National Guard, the light blue represented the Air National Guard. The badge in the center is the branch insignia of the National Guard Bureau. The two triangles in the upper fly are "flight devices" and represent the Air National Guard.
The version of the flag which appears in the information box at the top of the page was adopted in 2008 when the position of Chief of the National Guard Bureau was upgraded to full General (four stars).
