In the U.S. Air Force, wings are divided into groups, with the group being the level directly under a wing. A group contains several squadrons, and those squadrons are further divided into flights. So the hierarchy from larger to smaller goes: Wing → Group → Squadron → Flight. A Numbered Air Force is a higher command that oversees multiple wings, not a level beneath a wing. A squadron is below a group, and a flight is below a squadron. Therefore, the level directly under a Wing is the group.
