The Australian Defence Force's (ADF) ranks of officers and enlisted personnel in each of its three service branches of the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF) inherited their rank structures from their British counterparts. The insignia used to identify these ranks are also generally similar to those used in the British Armed Forces. The following tables show the "equivalent rank and classifications" for the three services, as defined in the ADF Pay and Conditions Manual. "Equivalent rank" means the corresponding rank set out under Regulation 8 of the Defence Force Regulations 1952.
