Final answer:
The Air Force Personnel Center supports AEF operations by managing assignments and personnel to ensure readiness. Historically, the AEF contributed significantly in WWI, with modern AEF operations focusing on deployment of Air Force units in missions like ISAF and Operation Enduring Freedom.
Step-by-step explanation:
All Air Force personnel contribute to the AEF. The Air Force Personnel Center (AFPC) supports AEF operations by managing assignments and personnel requirements to ensure that the AEF is properly staffed and equipped for its missions. In historical contexts, the American Expeditionary Force (AEF) played a crucial role in World War I under the leadership of General John J. Pershing. The AEF functioned as an independent force, aiding the exhausted Allies with fresh troops and eventually helping to turn the tide in favor of the Allies. In modern times, the AEF concept has evolved to describe the deployment of Air Force units and personnel for operations, such as those in Afghanistan under the ISAF mission and Operation Enduring Freedom, which involved pursuing al-Qaeda in difficult terrains.
