The Incident Command System
"On February 28, 2003 the President tasked the secretary of Homeland Security, as part of Homeland Security Presidential Directive-5, to provide a consistent nationwide approach for Federal, State, and local governments to work effectively and efficiently together to prepare for, respond to, and recover from domestic incidents, regardless of cause, size, or complexity. To provide for interoperability and compatibility among Federal, State, and local capabilities, the NIMS will include a core set of concepts,
principles, terminology, and technologies covering the Incident Command System; multi -agency coordination systems; unified command; training; identification and management of resources (including systems for classifying types of resources); qualifications and certification; and the collection, tracking, and reporting of incident information and incident resources. "

"AUXCOMM is an umbrella term and acronym for "auxiliary communications." It was developed by OEC in 2009 with the assistance of amateur radio subject matter experts. The concept behind the acronym was to educate as many amateur radio entities to work and train with public safety personnel, understand the value of the National Incident Management System (NIMS) Incident Command System (ICS) concept and the role of the communications unit leader (COML)."
Department of Homeland Security, Office of Emergency Communications

AUXCOMM is not a standard ICS position but is made up of amateur radio operators that provide auxiliary support to emergency management. AUXCOMM personnel are commonly utilized in Emergency Operations Centers (EOCs). AUXCOMM personnel are often used in catastrophic events when communications infrastructure has failed or has been compromised.
