The military ranks of the Ethiopian Army originally came from the traditional organization of their forces. An army in the field or in camp was composed of a vanguard, main body, left and right wings and a rear body. The titles of the upper level of officers reflected this organization: The traditional army units were organized on the decimal system and the titles of their commanders, the Basciai, reflected this organization: These ranks have been retained in the modern army, the upper rank titles of the army follow the European model.
