their immediate subordinates. The main HQs (known as 'main') is less mobile and is involved in both the planning and execution of operations. There are a number of staff assembled here from various staff branches to advise the commander, and to control the various aspects of planning and the conduct of discrete operations. A main HQ for a large formation will have a chief of staff (CoS) who coordinates the staff effort; in a smaller HQ this may be done by the second-in-command. The rear or logistic HQs ('rear') is some distance from the battle or front line in conventional operations. Its function is to ensure the logistical support to front line troops, which it does by organizing the delivery of combat supplies, materiel and equipment to where they are needed, and by organizing services such as combat medicine, equipment recovery, and repair.

The Japanese word honbu (本部) is generally used for that, also outside Japan. Sometimes they refer to these headquarters as honbu dojo (本部道場) in which dojo (道場) is a facility provided for practicing discipline, the training ground. Sometimes honbu is written as hombu, the way it is pronounced, but the Hepburn transcription is honbu in which the 'n' is a syllabic n. Notes References Isby, David C.
