In the armed forces, a signaller is a soldier or seaman in a Corps or trade responsible for military communications and related tasks. Most signallers are employed in the operation of radio communications equipment (other than personal radios), but other signallers may be responsible for the construction and maintenance of telephone lines and telephone switchboards for field telephone systems, information technology infrastructure, or electronic warfare.

In the past, signallers also operated heliographs, Aldis lamps, semaphore flags, and even carrier pigeons.

Air Force

In an air force, a signaller, an aircrew member, is a person trained to communicate between the aircraft and its base by means of radio or Aldis lamp. With improvement and simplification of radio communications equipment the role of a "signaller" in modern times is redundant. In the days when morse code telegraphy was the main means of communication a signaller was an important member of an aircraft's crew.
