 A "gruppe" was referred to in roman numerals, for example I./JG 2, while "staffeln" were described with their number (1./JG 2).The wing could be subordinated to a "Fliegerkorps", "Fliegerdivision" or "Jagddivision" (Flying Corps, Division and Fighter Division) all of which were subordinated to "Luftflotten" (Air Fleets).The use of "Fliegerdivision" became redundant and the description "Fliegerkorps" supplanted it until the use of "Jagddivision" later in the war.
