    Glossary of Luftwaffe Terms
    Erganzungsgruppen: training groups.
    Fernaufklaerungsgruppe: a long-range reconnaissance squadron; abbreviated (F) or FAG. The 1 (F) 123 would be the 3rd Squadron, 123rd Long-Range Reconnaissance Group.
    Fliegerdivision: an air division. Gradually replaced by the air corps in operational situations, but never entirely so.
    Fliegerfuehrer: special air command, usually under air fleet command. Although primarily concerned with antishipping or weather reconnaissance operations, they sometimes controlled fighter, bomber, and dive-bomber units. For purposes of this book, the term is used to designate the commanders or their commands (i.e., Fliegerfuehrer Afrika is translated as Air Commander Africa or Air Command Africa).
    Fliegerkorps: an air corps.
    Fliegerverbindungsoffiziere (“Flivos”): air force liaison officers attached to army units; responsible for coordinating reconnaissance, close air support, and other missions.
    Flugwetterdienst: the Air Force Meteorological Service.
    Geschwader: an air wing, the largest mobile, homogenous formation in the Luftwaffe.
    Gruppe: a group; the basic combat and administrative aviation unit of the Luftwaffe. Largely self-contained, the entire gruppe was usually based at a single airfield. It could be detached from its parent wing (geschwader). Gruppen were abbreviated II/KG 77 (II Group, 77th Bomber Wing), I/JG 3 (I Group, 3rd [Single-Engine] Fighter Wing), etc.
    Jagdfuehrer: “Fighter Commander.” Abbreviated “Jafu,” this division-level headquarters controlled fighter units in its area (Jafu Ostmark, for example, controlled fighter units in Austria and is translated “Fighter Commander Austria” or “Fighter Command Austria”).
    Jagdgeschwader: a single-engine fighter wing, abbreviated JG 1, JG 2, etc.
    Jagdkorps: an air corps consisting entirely or almost entirely of fighter units.
    Kampfgeschwader: a bomber wing, abbreviated KG 1, KG 2, etc. Lehrdivision: a testing division, responsible for testing the latest types of aircraft, antiaircraft defenses, and air signal units.
    Luftgau: corps-level air administrative districts responsible for administration and supply organizations, as well as recruiting, mobilization, and training; they had specific territorial responsibilities over set geographical areas. Luftgau functioned under the Air Ministry (Goering) and were designated by Roman numerals (Luftgau III) or locations (Luftgau Norwegen, or Air Administrative District Norway).
    Luftwaffe Command: a headquarters intermediate in status between air fleet and air corps; included downgraded air fleets (3d Air Fleet became Luftwaffe Command West in 1944, 2nd Air Fleet became Luftwaffe Command South in late 1944, and 4th Air Fleet became Luftwaffe Command 4 in 1945, for example).
    Nachtjagdgeschwader: a night fighter wing, abbreviated NJG 1, NJG 2, etc.
    Nachtschlachtgruppe: a night harassment wing. Established in 1944, they consisted of obsolete aircraft (Ar-65s, He-50s, etc.). Abbreviated NS 1, NS 2, etc.
    Nahaufklaerungsgruppe: a short-range reconnaissance unit, abbreviated NAGr, or (H). 1 (H) 32 would be 1st Squadron, 32d Reconnaissance Group (Short-Range).
    OKL (Oberkommando der Luftwaffe): The High Command of the German Air Force. The command organ of the Luftwaffe. Directed by Goering, the day-to-day operations of O.K.L. were supervised by the chief of the General Staff of the Luftwaffe.
    OKW (Oberkommando der Wehrmacht): The High Command of the Armed Forces. Directed by Field Marshal Wilhelm Keitel, this organization was nominally the immediate superior of OKL. Goering, however, refused to cooperate with Keitel, making the OKL, in fact, an independent body.
    RDL (Reichsministerium der Luftfahrt): The Ministry of Aviation.
