What does the text after the Unit ID mean?

A comment indicating an incident function or location will occasionally follow the unit ID. These are entered either by the dispatcher or by the Incident Commander (IC) on scene. The IC will use these comments to keep track of fireground assignments and alert incoming units of the current incident organization. Dispatchers primarily use comments as reminders of special statuses. These comments are particularly valuable since all dispatch terminals can see them, including those in the dispatch center and those in the responding units. The comments also become part of the incident history that is later useful in determining when key events occurred (i.e. Safety Officer assigned, Hat Mat Team enters hot zone, etc.).
