Between 1937 and 1945 the Japanese Imperial Army formed 126 Independent Mixed Brigades (numbered 1–136 with some gaps), typically composed of various units detached from other formations. Some were composed of separate, independent assets (usually Independent Infantry Battalions). These brigades were task organized under unified command and were normally used in support roles, as security, force protection, POW and internment camp guards and labor in occupied territories. An Independent Mixed Brigade had between 5,000 and 11,000 troops.

History

The first two of these Independent Mixed Brigades formed by the Kwantung Army in the 1930s were the IJA 1st Independent Mixed Brigade and the IJA 11th Independent Mixed Brigade. Each of these brigades was organized in a unique manner; the 1st was disbanded in 1937 while the 11th was formed into the IJA 26th Division in 1938.

Later a series of Independent Mixed Brigades were formed for the purpose of garrisoning the large territories of China captured in the early phase of the Second Sino-Japanese War. This variety for China was usually organized with five infantry battalions, an artillery unit, and labor troops. In the Pacific theater they had different and more varied configurations of subordinate units.

The Hong Kong Defence Force, which was established in 1942 to occupy Hong Kong, was equivalent to an Independent Mixed Brigade.
