On 1 April 2006 Expeditionary Air Wings (EAWs) were formed at nine of the RAF's Main Operating Bases. Each EAW has its own identity and is led by the Station Commander, supported by his Station management team. The deployable elements of the station structures form the core of each EAW, reinforced by elements of the Air Combat Service Support Units (ACSSUs). Flying and Force Protection force elements are attached to meet the requirements of each operation. EAWs enable the RAF to train as cohesive units of Air Power which are prepared and capable of transitioning quickly from peacetime structures and deploying swiftly on operations in tailored packages.
