During peacetime, the Chief of the Defence Force is the only four-star officer in the ADF (admiral, general, or air chief marshal). The CDF is assisted by the Vice Chief of the Defence Force (VCDF) and serves as the Chairman of the Chiefs of Service Committee, composed of the service chiefs: the Chief of Navy (CN), Chief of Army (CA), and Chief of Air Force (CAF), all of whom are three-star officers (vice admiral, lieutenant general, and air marshal), as is the VCDF.
