ICS for Ham Radio Operators
The Incident Command System (ICS) is the standardised management framework used by emergency responders across the United States. For ham radio EmComm operators, understanding ICS is not optional — it is essential. When you deploy to an Emergency Operations Centre as an ARES operator, you are working within someone else's ICS structure. Operators who understand ICS integrate smoothly. Those who do not create confusion at the worst possible time.
The ICS structure
ICS organises emergency response into a scalable hierarchy. At the top is the Incident Commander (IC) with overall authority. Under the IC are four sections: Operations (doing the response work), Planning (tracking resources and situation status), Logistics (supporting the response), and Finance/Administration (tracking costs). Communications falls under Logistics — specifically under the Communications Unit, led by the Communications Unit Leader (COML).
Amateur radio EmComm operators typically report to the COML or the radio officer in the Logistics section. During a deployment you take direction from the incident command structure — not from your own ARES leadership.
The Communications Unit
The Communications Unit (COMU) is responsible for all communications systems at an incident — radios, phones, internet, satellite, and amateur radio EmComm support. The COML develops the Incident Communications Plan (ICS-205), documenting all frequencies, channels, and assignment details for the incident. Ham radio operators at an activation should receive a copy of the ICS-205 and operate only on the frequencies specified in the plan.
Your primary job at an EOC is to serve the served agency's communications needs as directed by the COML — reliably, available, and proficiently. Not according to your own preferences or ARES standard operating procedures unless they align with the incident plan.
| Form | Name | EmComm Use |
|---|---|---|
| ICS-205 | Incident Radio Communications Plan | Frequencies and channel assignments for the incident |
| ICS-213 | General Message Form | Standard format for passing formal message traffic |
| ICS-214 | Activity Log | Operator's personal log of actions during the incident |
| ICS-309 | Communications Log | Log of all radio traffic at a communications position |
| ICS-217A | Communications Resource Availability Worksheet | Documents available radio resources and capabilities |
Required and recommended courses
ICS-100 and IS-700 are the baseline requirements for most ARES sections — both free online at training.fema.gov, completable in a few hours each. ICS-200 is the next level and recommended for operators who expect to serve in leadership roles. For operators who aspire to become Communications Unit Leaders — the professional EmComm leadership role — the FEMA All-Hazards COML course is the career-level qualification, requiring ICS-100, ICS-200, and IS-700 as prerequisites.
Using ICS in practice
The best way to integrate ICS skills is to use ICS forms and language in every exercise and activation. Use ICS-213 forms for message traffic in exercises. Keep an ICS-214 activity log during Field Day. Use proper ICS check-in and check-out procedures in exercises. When these habits are routine, they transfer naturally to real activations without additional thought.
Why do ham radio operators need to know ICS?
Because you will be working within an ICS structure during a real activation. Emergency managers expect all deployed resources — including amateur radio operators — to understand and operate within ICS. Operators who show up without understanding ICS structure or chain of command are disruptive rather than helpful.
What is the COML and how does an EmComm operator relate to that role?
The Communications Unit Leader (COML) is the ICS position responsible for all communications at an incident. As a deployed amateur radio operator, you report to the COML or their designated representative — not to your own ARES leadership. The COML is your supervisor during the deployment.
Are ICS-100 and IS-700 difficult to complete?
No — both are designed for a general audience with no emergency management background. ICS-100 takes roughly 3 hours, IS-700 roughly 4 hours. Both are multiple-choice and self-paced. Certificates are issued immediately upon completion.
Can I take ICS training online?
Yes — ICS-100, ICS-200, IS-700, and IS-800 are all available free online at training.fema.gov. Higher-level ICS courses and the COML qualification require in-person attendance, but the entry-level courses required for most EmComm participation are all online and self-paced.
