That is not always true. Fire Marshalls are not part of American firefighting in many places. In fact there is only a small handful of depts around here and in a few more in the country that even operate that way. In most of the country it's a police investigator, or fire investigator supplied by the county, state, police dept whatever, the fire coordinators, and the fire chiefs that do the fire investigations with any arrests done by actual police officers. Fire Investigation is most times a joint effort of the police and fire aspects of emergency services. Also a Type 2 is not a Brush Truck, a brush truck is actually a Type 6 if you live in an area that uses those type designations, most places don't, they just call them by name. A type 2 is I believe a 2-door Pumper which coincides with the staffing of 3 which is the most an enclosed cab 2-door can have. Fly Cars shouldn't be needed for certain calls because they have 2 purposes in real life.
1. BLS First Response from a FD or EMS agency to a scene to handle the on scene duties until an ambulance arrives.
2. Providing a paramedic to a non-Paramedic ambulance for calls that involve cardiac, IVs, respiratory distress, etc.
The 3rd is not as common but some EMS agencies have a supervisor, chief or line officer that responds to calls with ambulances in the district. USAR we really need some options before they could implement that because Urban Search & Rescue is not used in a rural setting, it's completely different. district boundaries and fire hydrants are the main thing we need right now along with the ability to train employees to different levels of EMS care, whether that be all 6 in NY, or the 5 in other states or 4 whatever.
Interesting about type 2 and 6 units. For now I think we should use Type 2 fire engines as brush truck and then when we get some more wildfire type calls then add brush trucks.
I also think as we are talking about brush units there should be 2 types: the first one would be the 2-3 crewed type and the second would be a multi role vehicle that combines a type 1 with a brush enabling it to deal with both Calls that require either unit.
In regards to USAR it's interesting to hear that they only operate in cities, here in my county in the UK USAR go wherever they are needed.
