Who does the project officer collaborate with regarding items like invites and programs during a Change of Command?

The correct answer is the Wing Protocol Office, as this office typically handles the logistics and ceremonial details surrounding events such as a Change of Command. The role of the Wing Protocol Office includes managing invitations, programs, seating arrangements, and other formalities that are essential to the proper execution of military ceremonies. Their expertise ensures that the event complies with service customs and traditions, which is critical in maintaining the decorum expected during such significant military transitions.

While the Operations Support Office, Commanding Officer's Staff, and Personnel Support Office may have roles to play in the overall planning and execution of a Change of Command, they are not primarily responsible for the ceremonial aspects that the Wing Protocol Office oversees. These other offices may support by providing administrative resources or personnel, but the specific collaboration regarding invites and programs is best suited to the Wing Protocol Office.
