Oriental blue and silver gray are the colors traditionally associated with Military Intelligence. The invected chief is an allusion to clouds and the atmosphere, the main field of operations for a combat electronic warfare intelligence unit. The sunburst, a symbol of Helios, the Greek sun god, is a further reference to the atmosphere. The sunburst may also denote a compass rose and the multi-directional facets of the unit's radio functions. The checky background alludes to a chessboard and symbolizes strategy and intelligence. The sword refers to the unit's military ability, the lightning flash to speed and communications, and the key to intelligence and security.
