The role of the Royal Australian Corps of Signals (RASigs) is to provide communications, information systems and electronic warfare (CISEW) support to the Army and the Australian Defence Force to allow command and control of deployed forces in peace, crisis and conflict on any operation anywhere in the world.

Utilising the electro-magnetic spectrum, communications systems, information technology and electronic warfare, the Royal Australian Corps of Signals will enable highly dynamic Command and Control whilst disrupting that of any adversary. It is a respected and vital part of the Army that is proud of its heritage, operates cutting-edge technology, and always is looking to the future.

On the battlefield, RA Sigs provides commanders with the means of controlling the battle using road and air dispatch services, radio, fibre optic microwave and satellite links. By planning, deploying and maintaining robust, scalable, secure local and wide area networks, RASigs ensures the Army's information services are available 24/7 anywhere in the world.
