A large number of ground support units support these flying squadrons, including three expeditionary combat support squadrons, two airfield defence squadrons and communications, radar and medical units.

The wing consists of three expeditionary combat support squadrons, one combat support squadron, an operations support squadron, a combat logistics squadron and two support units, which are located at various bases all around Australia, and in Malaysia at RAAF Butterworth.

At each base, the group was composed of a material squadron, a troop carrier squadron, a tactical hospital or dispensary, and a combat support squadron.

This formed part of a reform across the RAAF in which the reserve squadrons were merged with local combat support units or expeditionary combat support squadrons with the goal of improving the provision of air base support services.

The majority of Aero Squadrons were combat support squadrons.

Helicopter Combat Support Squadron Seven HC-7 Sea Devils was a combat support squadron of the United States Navy established in 1967 and deactivated in 1975.
