Throughout its history, the corps has deployed members to support Australian forces deployed on operations. Initially, they deployed to Japan as part of the British Commonwealth Occupation Force, where they provided education support for service personnel and their children. Later, members of the corps were sent to Korea during the Korean War, where they were attached at battalion level to provide soldiers with training in the field. During the Vietnam War, RAAEC personnel were deployed to support the 1st Australian Task Force at Nui Dat.
