Notes:

(1) British Army Regiments were used as administrative rather than field units. In most armies, divisions were divided into either brigades or regiments but rarely both.

(2) U.S. Armored Division Command Commands were brigade equivalents.

(2) Large Air Force units were often regionally or functionally organized and varied greatly in size. In particular, the R.A.F. used numerous ad hoc nomenclatures for Command-sized units (ex: Desert Air Force, 1st/2nd Tactical Air Forces, Air Defense of Great Britain).

(3) French Zone d' Opérations Aériennes (Z.O.A.) were regional commands composed of various Groupes. Bomber Groupes of the Z.O.A.N. (Nord) were organized under the 1ére Division Aérienne, the only such formation of its kind and which would be equivalent to a USAAF wing in size. Al Z.O.A.s facing Germany were organized into the Forces Aériennes de Coopération du Nord-Est (F.A.C.N.E.).

(4) There was no RAF equivalent to a USAAF Wing or Luftwaffe Geschwader. RAF Groups were typically composed of a very large number of Wings.

(5) Regia Aeronautica Brigata (Air Brigade) and Divisione (Air Division) were only differentiated by number of Stormo under their command (2 or 3 respectively).

(5) Japanese air unit translations:

Air Army (Kokugun), Air Division (Hikoshidan), Air Brigade (Hikodan), Air Combat Group (Sentai), Squadron (Chutai), and Flight (Shotai).
