The correct order of Air Force units from large to small is MAJCOM, Wing, Group, and Squadron. This hierarchy starts with MAJCOM, which stands for Major Command. MAJCOMs are the largest organizational units within the Air Force, overseeing major operational areas such as air combat, logistics, training, and support.

Next in the hierarchy is the Wing, which typically commands a significant number of aircraft and personnel and is responsible for the operational readiness of its assigned mission. Wings can be composed of multiple groups, each with specific functions (such as operations, maintenance, and support).

Following the Wing is the Group, which consists of several Squadrons that specialize in particular aspects of the Wing's mission. Groups often manage the consolidated operations of several squadrons and provide support functions.

Lastly, the smallest unit in this hierarchy is the Squadron. Squadrons are typically organized around specific missions or operational tasks and are the building blocks of the Air Force structure.

This structured order is essential for efficient command and control within the Air Force, allowing for effective management of resources and personnel as the organization scales from the broader strategic level at MAJCOM down to specific operational units in Squadrons.
