Note: Some GCE battalions and regiments are provided air liaison officers/forward air controllers (i.e., Marine Corps naval aviators — aircraft pilots, and naval flight officers — airborne weapons and sensor systems officers) with specialized skills in coordinating air support of ground units) from the Marine Aircraft Wing (MAW) of the aviation combat element (ACE). These officers facilitate employment of Marine aviation in support of GCE units to perform offensive air support (e.g., close air support), assault support (e.g., troop, cargo, and casualty transport, aerial command and control, liaison, communications, and illumination, and close-in fire support by light/attack helicopters), and aerial reconnaissance (e.g., tactical reconnaissance and artillery spotting).
