Japanese task-force thinking concentrated on cruiser and destroyer groups assembled for offensive operations, particularly night fighting. Bringing in multiple carriers or capital ships pushed an operation toward a larger fleet formation. The decisive battle belonged to the Combined Fleet and its senior seagoing commander, while major amphibious operations also passed through that command. Attrition groups needed to operate independently while limiting radio transmissions that could reveal their positions. This spread command responsibility across detached units while leaving much of the doctrinal case for decentralization tied to attrition warfare.

Cruiser and destroyer attrition groups needed distributed command, while decisive battles and major amphibious operations remained under the Combined Fleet.
