Signaller (Canadian Army)

The Communications and Information Systems (CIS) Operator is the trade that makes every other trade able to talk. Without communications, nothing else the army, navy, or air force does is coordinated. That is not a figure of speech — in a contested environment, communications are as much a weapons system as a rifle or a tank gun. The CIS Op understands this. Whether the people they support fully appreciate it is another question. In the Army, the CIS Op is the soldier who installs the tactical radio network, runs the satellite terminals, maintains the data links, and troubleshoots everything that has a power button when it stops working at three in the morning on exercise. The work is technically demanding, physically present in every tactical environment, and critically important while being largely invisible when done right. The trade spans all three environments. Army CIS Ops work at the section, battalion, and brigade level. RCN communicators operate aboard ship and at shore establishments. RCAF CIS technicians maintain the communications infrastructure that keeps aircraft flying and controlled. The specific role depends on your initial posting, and postings within the CAF are not always predictable. The honest recruitment picture: CIS Op is a trade that translates well to civilian employment, which means the CAF has a retention challenge. The skills you build in three to five years — network administration, satellite communications, radio frequency systems, cybersecurity fundamentals — are exactly what the private sector will pay you well for when you leave. Some people leverage that quickly. Some people make the CAF their career. Both are reasonable choices. Just know that civilian employers will recognize what you know, and plan accordingly.
