WHAT COMMUNICATIONS & ELECTRONICS MEANS IN THE CAF
COMMUNICATIONS (Voice/Data/Radio)
Radio, satellite, microwave, voice, data and message systems that move information between commanders, headquarters, ships, aircraft, vehicles and deployed forces.
INFORMATION SYSTEMS (Networks/Servers)
Computer networks, routing, switching, servers, enterprise systems, deployable IT, data services and user support.
ELECTRONICS (Radar/Nav Aids)
Electronic equipment such as radar, navigation aids, control systems, cryptographic devices and technical infrastructure that make operations possible.
SPECTRUM & SECURITY (EW/COMSEC/Cyber)
Electronic Warfare, Communications Security, cryptography, network defence, vulnerability reduction and cyber support to operations.
OPERATIONAL ENABLEMENT (C2/Readiness)
The end purpose — give commanders reliable Command and Control so they can sense, decide, direct and fight across all domains.

WHAT A CELE OFFICER ACTUALLY DOES
ADVISE COMMANDERS
Translate technical capability into operational language — what works, what does not, what is risky, and what must be prioritized.
LEAD PEOPLE AND TEAMS
Command or supervise technicians, operators and support staff; set standards; develop junior members; enforce readiness and discipline.
GENERATE AND SUSTAIN READINESS
Ensure systems are available, maintained, secure and configured for the mission; report serviceability and operational limitations honestly.
INTEGRATE MULTIPLE SYSTEMS
Make radios, satellite links, networks, airfield systems, cryptography, electronic systems and user needs work together as one C2 system.
MANAGE RISK AND RESOURCES
Balance people, equipment, spares, training, time and money. Decisions on what must be fixed now, what can wait, and where redundancy is required.
BUILD FUTURE CAPABILITY
Contribute to policy, procurement, capability development and modernization so the force does not fall behind in communications, electronics and cyber.
"The CELE officer exists to LEAD, INTEGRATE, ADVISE and SUSTAIN the C&E system."
