Which organization typically manages the distribution of readiness spares packages?

The distribution of readiness spares packages is typically managed by the Major Command (MAJCOM). MAJCOMs are responsible for overseeing and coordinating various aspects of logistics and supply chain operations within their command structure. This includes ensuring that units have the necessary spare parts and readiness materials to maintain operational capabilities.

The MAJCOM's role encompasses managing the resources and logistics necessary to support the readiness of forces, which involves strategic planning and allocation of spares. They interface with other logistics entities, ensure compliance with procedures, and ensure that the right products and parts are delivered to meet operational readiness requirements.

The other options relate to different aspects of logistics management. Base operations focus more on the day-to-day functioning of the base rather than broader logistics management. The Air logistics office may handle specific logistics issues but generally reports to or operates under the guidance of the MAJCOM. Lastly, the supply chain management office deals with logistics at an operational level but typically works in conjunction with MAJCOM directives and resources.
