Chook
Signallers are known as 'Chooks' throughout the Australian Army. It is believed the nickname originally came about during the Vietnam War. The Signallers of 152 Signal Squadron SASR, based at Nui Dat were placed in a small shack resembling a Chook Pen. With all the chatter over the radios heard from outside, they sounded very much like chooks - hence the nickname.
