The Royal Australian Corps of Signals (RASIGS) keeps every part of the Australian Army in touch. Its motto is Certa Cito (swift and sure).

Modern Army command and control systems demand reliable, high speed transfer of large volumes of data. The communications systems provided by Signals must keep pace with modern information technology. The control of the electromagnetic spectrum offers a decisive advantage in modern warfare and Electronic Warfare, listening to or interfering with enemy electronic transmissions, is a critical Signals contribution to the Army's combat capability.

On the battlefield Signals provides commanders with the means of controlling the battle using road and air dispatch services, radio, microwave and satellite links. A high technology computer switched digital network, capable of providing a high quality, high capacity, secure communications network is being introduced.

The Corps has recently taken over the responsibility for Army Information Systems. Signal Corps personnel now control large integrated information systems and are responsible for the installation and operation of local area networks using state-of-the art computer equipment.

Specialist roles in the Corps include radio operators, linesmen, riggers, technicians, systems operators and electronic warfare operators.

The Royal Australian Signals is divided into a number of regiments and squadrons, both regular army and army reserve. Each brigade of the army has a signals squadron which forms part of the brigade's Command Support Regiment. The army's two divisions each has a signal regiment.
