For years, the Royal Australian Corps of Signals (RASigs) organised itself around a simple idea: that expertise could be neatly divided into trades. Communications belonged to one group, networks to another, electronic warfare to yet another.

It made sense in a world where technology was segmented and the battlefield was comparatively predictable. But what happens when the environment changes faster than the institutions built to operate within it?

The Employment Category Review (ECR) is not merely a personnel reform. It is an acknowledgement that the Corps' greatest challenge is no longer generating specialists for separate functions, but building a workforce capable of operating across them.

What Is Happening?

If you have served in RASigs in the last decade, you know the trade structure by heart: Information Systems Engineering, Battlespace Communications Specialist, Electronic Warfare, and Telecommunications Network Engineering.

Four other-ranks employment categories, each with its own school pipeline, its own culture, and its own quiet conviction that it was the one doing the real work.

Before anyone writes in: Cyber Warfare Specialist is absent from that list on purpose. They are still Signallers, but ECN 664 is Army’s contribution to a joint category now and sits outside this review.

All four are being disestablished.

In their place, the RASigs ECR proposes three new categories: Land Combat Signaller (ECN 600), Cyber Systems Technician (ECN 601), and Electromagnetic Operations Specialist (ECN 602).^[1] ECN 664 Cyber Warfare Specialist will remain as is.

For anyone still serving, this is the most consequential change to Signals career management in a generation. For anyone who has separated and wondered about coming back, it reshapes what you would be coming back to. Here is what the new structure actually looks like.

Why Is the Corps Doing This?

The stated driver is threat. Australia's strategic circumstances have shifted, and the 2023 Defence Strategic Review, the 2024 National Defence Strategy (NDS), and the 2026 NDS all push the ADF towards a focused, integrated, multi-domain force.^[2] The 2026 NDS, released on 16 April 2026 alongside the Integrated Investment Program, builds on the strategy of denial adopted in 2024 and sharpens the emphasis on self-reliance and deterrence.^[3]

Adversaries are investing heavily in combined cyber and electronic warfare capability. The result is a battlespace that is both contested and transparent, where friendly communications, data integrity, and decision-making are all exposed to disruption and exploitation.

The review's judgement is blunt and will not surprise anyone who has spent a field exercise babysitting a terminal: the existing RASigs workforce model is weighted too heavily towards platform provisioning, which limits cyber-enabled warfighting effectiveness.

There is a second, more familiar driver: workforce health. Across the four legacy categories, none was at full strength.

Information Systems Engineering sat at 85 per cent with no growth over 12 months. Battlespace Communications was at 79 per cent. Electronic Warfare was at 76 per cent and shrinking, with a separation rate above 8 per cent.

Telecommunications Network Engineering held the best strength figure at 94 per cent but was also trending down. Every category was assessed as insufficient, and three of the four as deteriorating.

Five other-ranks categories is a lot of structure for a workforce of this size. The ECR’s argument is that rigid categories have produced siloed, inflexible employment models at exactly the moment Cyber Command and Space Command integration is stretching supply thinner.

The most pointed example is electronic warfare, which under the old model was constrained to a single ECN: one trade holding a mission set the whole Corps increasingly needs to touch.

What About Doctrine?

The new structure maps onto Land Note 6.0.9 and the concept of Land Cyber Operations:the threat aware employment of cyberspace and the electromagnetic spectrum to enable and defend friendly force decision superiority.^[4]

That concept divides the Cyber Domain into Cyberspace Operations and Electromagnetic Operations. Underneath sit the mission sets: cyberspace security operations, cyberspace provisioning, cyberspace warfare, and electromagnetic spectrum (EMS) operations.

The associated specialisations include signals intelligence, spectrum management, offensive and defensive cyber, and mission data operational support.

Under the old structure, the review found these mission sets were supported ineffectively, with trades misaligned to the functions they were meant to deliver.

The new model puts ECN 601 against cyberspace operations, ECN 602 against electromagnetic operations, and ECN 600 underneath both as a common baseline. Electromagnetic Warfare is normalised rather than quarantined, and specialisation becomes elective and role-based rather than a decision locked in at recruiting.

Who Is the ECN 600 Land Combat Signaller?

The Land Combat Signaller (LCS) is the entry-level signaller, and the feeder category for both technical trades. LCS soldiers are mentored by Cyber Systems Technicians and Electromagnetic Operations Specialists both, and progress into one field or the other.

The LCS will deliver the common baseline for Signallers at a foundation level, providing entry-level support in the EMS and cyberspace.

In plainer language: every Signaller comes through the same front door, learns the same fundamentals, and chooses a direction afterwards rather than at the recruiting desk.

If you are currently serving in one of the legacy categories, note that the ECN 600 transition is aimed at the Reserve and in-training workforce. Trained full-time members will not transition into 600 and will be given the opportunity to specialise into either 601 or 602.

Who Is the ECN 601 Cyber Systems Technician?

The Cyber Systems Technician is not available for direct entry from civilian life. There is no recruiting pipeline straight into 601. Members transferring into the trade must first complete Land Combat Signaller, then transfer, then complete the CST Foundation Course.

The CST enables command and control by delivering information and communication technology services and by supporting mission sets in the Cyberspace as outlined in Concept Cohere.^[5]They will follow a training pathway completing Subject 1, Subject 2, and Subject 4 courses plus a suite of electives and role based training as required, whether that is long range fires, littoral, or related to the information system that will save us all: Warfighting Network and Applications (WNA) under JP 9111.

The practical effect is a trade that keeps technical depth and command progression in step, rather than forcing a choice between them. That has been a persistent complaint under the legacy structure.

Who Is the ECN 602 Electromagnetic Operations Specialist?

The Electromagnetic Operations Specialist (EOS) mirrors 601 structurally: the same entry rule, the same-paired technical and leadership continuum, and the same progression through to warrant officer. It is likewise closed to ab-initio entry: members must complete ECN 600 initial employment training before specialising.

What is different is the scope of Electromagnetic Warfare. Where Electromagnetic Warfare was a single, narrow category, EOS sits across the electromagnetic operations function.

That includes detecting, exploiting, and attacking adversary forces; protecting friendly forces; and managing the electromagnetic operating environment across the full spectrum of competition through conflict.

For the ex-bears (Electromagnetic Warfare operators) in particular, this is worth attention: the trade you left is not the trade being created.

What Happens Next?

The ECR sets out a five-phase approach. Employment category approvals were completed between November 2025 and February 2026.

The next phase, running from March to December 2026, focuses on industrial relations and taking the submission through to a determination by the Defence Force Remuneration Tribunal (DFRT). From August 2026 to July 2027, the focus will shift to preparing systems, the workforce, and training arrangements.

Transition and training will then run from July 2027 to 2029, including gap training and adjustments to existing training continua. The implementation will conclude with a control and assurance phase from 2029 to 2031.

If this sounds complex, that is because it is. And it needs to be.

The DFRT is the independent statutory body that determines ADF salaries and salary-related allowances, and it has ruled on RASigs category structure before. The Corps last went to the Tribunal on employment category design under the Royal Australian Corps of Signals Modernisation matter, which reshaped the combat signaller, information systems, electronic warfare, and telecommunications systems categories^[6]. Tribunal decisions are published, so the determination arising from this submission will be a matter of public record.

What Should Members Do About It?

If you are serving, your transition is individual, and the detail that matters will arrive in your transition letter.

Between now and then, the conversations worth having are with your career manager and your RSM about which of the two technical categories your experience and interests actually point towards. Under this model, that becomes an elective decision rather than an artefact of what you were recruited into.

If you have separated and are considering Reserve service or re-entry, the entry point can be Land Combat Signaller or the appropriate skill grade within 601 or 602.

Recognition of prior service will depend on what skill grade you held within which trade.

One caveat for everyone: this is a submission progressing to DFRT determination, not a settled state.

Category names and training continuums as described here reflect the proposal at ECR Remuneration Committee stage. Confirm specifics with the Employment Category Management team, your career manager, and your chain of command before making a career decision.

So What?

Corps restructures have a reputation. Most serving members have sat through at least one town hall that promised transformation and resulted in minor tinkering around the edges rather than fixing actual structural problems.

This one is doing something more substantial. It does not simply rename the trades; it moves where the boundaries sit, puts every Signaller through the same front door, and makes specialisation a choice made in uniform rather than an accident of what the recruiter had open that month.

Whether it works has very little to do with the submission and everything to do with 2027 and 2028, when the training system has to build the courses and career managers have to make several thousand individual transitions land.

Structural reform is easy to endorse in a slide deck and hard to deliver in a training establishment.

For now, the practical advice is unglamorous. Read the transition letter when it arrives. Have the conversation with your career manager before it does. Decide honestly whether you are drawn to the network or the spectrum, because for the first time the answer is genuinely yours to give.

And if someone tells you this is the end of the Corps as you know it, take it gently: they said the same thing last time, and Jimmy badge is still on the hat.
