This is a list of Groups in the United States Air Force that do not belong to a host wing.
The last level of independent operation is the group level. When an organization is not part of the primary mission of the base it will be made an independent group. They may report to a wing or they may be completely independent (the 317th Airlift Group at Dyess Air Force Base). They may also be organized as an expeditionary unit, independent but too small to warrant a wing designation. The organization of the independent group is usually similar to the operations group, but with a few squadrons or flight from the support side added to make the organization more self-sufficient, but not large enough to become a wing.
