Editing Sentai (section)

==Imperial Japanese aviation ''sentai''==
The term was used during [[World War II]] by the [[military of the Empire of Japan]] for [[Imperial Japanese Army Air Service]] (IJAAS) and [[Imperial Japanese Navy Air Service]] (IJNAS) [[military aviation]] units equivalent to a group or wing in other air forces. However, the term had slightly different meanings in the IJAAS and the IJNAS.

An IJAAS ''Sentai'' was made up of two to four [[Squadron (aviation)|squadrons]] (''chūtai''). In the IJAAS, two or more ''Sentai'' comprised a ''hikōdan'' (air [[brigade]]). In the later stages of World War II, the IJAAS abolished ''chūtai'' and divided its ''sentai'' into ''[[hikōtai]]'' (flying units) and ''seibitai'' (maintenance units). A ''sentai'' commander (''sentaichō'') was generally a [[lieutenant colonel]].

In the IJNAS, a ''sentai'' was a larger unit: a ''[[Kōkūtai]]'' was the equivalent of an IJAAS ''sentai''. Several ''sentai'' made up a ''kantai'' (air fleet). In the IJNAS, a ''Sentaichō'' was usually a [[Captain (naval)|naval captain]].
