Depends on what unit I have available for fires at the time. Station 1 is staffed with 2 BLS and 2 ALS Engines, plus 3 ALS Ambulances, then the normal set up in the bays. Then a Brush, HES, BC, and EMS Supervisor vehicles out back. 1: One ALS or BLS as primary, then more BLS or ALS Engines as needed. 2: Depends on the extent of the MVA and what units are available. Typically one or two squad cars. Now the actual dept I send varies on which law enforcement unit is closest by. Now if there is a fire, and there happens to be an engine returning to the station close by, I grab it. Otherwise I favor a an ALS Engine as the deck gun will put the fire out by it self if treated in time and that leaves the personnel to treat the injured until an ALS and or BLS ambulance(s) can arrive for further treatment and transport. If extrication is needed, then I have HES at both stations and will dispatch one of them. 3: ALS or BLS as primary again and more ALS or BLS engines as needed. 4: If its just a person with a hand gun I send a SWAT SUV(FBI SUV modified to hold SWAT personnel instead.), try to flash bang if possible and arrest them. Now if its a person with a rifle, I send the water cannon and usually just let that shoot him until he needs medical care.
