The Eagle, Globe, and Anchor is the official emblem and insignia of the United States Marine Corps. It is commonly referred to as an EGA, although this usage is discouraged by the U.S. Marine Corps. The current emblem traces its roots in the designs and ornaments of the early Continental Marines as well as the United Kingdom 's Royal Marines. The present emblem, adopted in 1955, differs from the emblem of 1868 only by a change in the eagle. Before that time many devices, ornaments, ribbons, and distinguishing marks followed one another as official badges of the corps.
