ShieldMaroon is a color traditionally associated with the Medical Corps, the original organization. The fess wavy azure symbolizes crossing the sea with the American Expeditionary Forces. The charges in chief, the Lone Star of Texas with a giant cactus superimposed, are indicative of the service of the 1st Ambulance Company on the Mexican Border, which is the connecting link between the parent unit's first service and previous to World War I.
