Some EMS training, if not for the community, at least for your fellow firefighters.
In the modern fire service, if a guy (or gal) only wanted to put water on fire and nothing else, they're going to be hard pressed at finding a job (or keeping that job). Nearly every firefighting course I've been through has had a unit on emergency medical care. Not only EMS, but it's intertwined with all sorts of SAR-both ground and structural, rescue, hazmat of all levels, etc. It's expected that upon arrival, there will be a suggested solution (preventing fire, injury, death, worsening) to most problems and bad situations, many of which, do not involve live fire.
