Which term describes the organization containing two or more subordinate units?

The term that describes an organization containing two or more subordinate units is "Group." In military structure, a group typically consists of several squadrons, which allows for a broader scope of operations and administration. This hierarchical organization enables the management of multiple units under a unified command structure, facilitating coordination and efficiency in executing missions.

A group serves as a key organizational layer within the Air Force, providing support and resources to ensure that subordinate squadrons can function effectively. This is crucial in operations, as it allows for the integration of capabilities and personnel across different units. While squadrons and flights are also important organizational units, they are generally designed for more focused tasks and do not inherently possess the same level of multi-unit coordination as a group does. The term "division" is used in other branches of the military but typically refers to larger formations than are standard in the Air Force structure.
