What organizational structure is focused on ensuring the readiness of assigned forces?

The organizational structure that is focused on ensuring the readiness of assigned forces is the Numbered Air Force. This structure is specifically designed to provide operational command and control over air forces, ensuring that they are ready to carry out their missions effectively. The Numbered Air Force is responsible for training, equipping, and maintaining combat-ready forces, and it typically oversees specific operational and training requirements tailored to the needs of their assigned units.

The role of the Numbered Air Force includes readiness assessments, deployment activities, and logistical support, making it a critical part of the military hierarchy aimed at ensuring that air units are prepared for immediate and sustained operations. This focus on readiness distinguishes it from other organizational structures, which may have broader strategic or administrative roles without the same level of emphasis on preparing forces for immediate action.
