# List of Japanese military detachments in World War II

Detachments (支隊, shitai) were particular military formations of the Japanese Imperial Army. Detachments were a force of infantry, artillery, armor, and other support units which were temporarily assigned for independent action and had a special mission. Generally such units were named after a leader, for example the Ichiki Detachment was named after Kiyonao Ichiki, and the Yasuoka Detachment was named after Masaomi Yasuoka. Some were named after a location, such as the Aoba Detachment. These designations also often referred to the core or main force under personal command of its operative chief within a division or another Army unit.
The Japanese Imperial Navy also used such formations in special assignments.
