The mountain and evergreen tree represent the unit's location in the state of Washington. These two elements also allude to the "heights" of achievement as suggested by the unit's motto. The dark blue wavy bar in the mountain's base is for the great water areas of the Pacific Northwest. The tower and the fleur-de-lis symbolize the unit's World War II campaign participation in the European theater. Dark blue and red are the colors of the Adjutant General's Corps; gold is for excellence.
