Signaler

A signaller in the armed forces is a specialist soldier, seaman or airman responsible for military communications. Signallers, a.k.a. Combat Signallers or signalmen or women, are commonly employed as radio or telephone operators, relaying messages for field commanders at the front line (Army units, Ships or Aircraft), through a chain of command which includes Field headquarters and ultimately governments and non government organisations. Messages are transmitted and received via a communications infrastructure comprising fixed and mobile installations.

In the past, signalling skills have included the use of: Heliograph, Aldis lamp, semaphore flags, "Don R" (Dispatch Riders) and even carrier pigeons.

Modern signallers are responsible for the battlefield voice and data communication and information technology infrastructure, using a variety of media. All types of wire (line), satellite and ionospheric radio communication are employed. These include common radio systems such as HF/VHF radio and UHF/SHF radio (operated in line of sight, for example). Cellular radio and telephone systems such as TETRA are also becoming common.

In addition to day-to-day soldiering, the signaller is required to be competent at a number of skill levels in the following topics:

In an air force, a signaller, an aircrew member, is a person trained to communicate between the aircraft, its base and units in the area of operation, by means of radio or other digital communications.

In the Australian Army, a signaller is often referred to as a Chook (Australian Slang for Chicken) by soldiers outside the Signal Corps, because the Morse code used by Signallers has been likened to the chirping of chickens.
