Today we see our fire fighters being first responders to most if not all medical calls. Most fireman are now cross trained as EMTs, though not as much as those you find in ambulances, they are also not as well equipped as an ambulance. With that in mind it would be nice to see fire fighters be able to treat minor injuries (say about 10% of health max per person per life, I mean we can't make EMS pointless) and be able to resuscitate people. Hell instead of resuscitating people they can have a way to get someone "stable" till medics do arrive and can resuscitate. I am not bias, I see a reason for both. Best RP, though, is a more realistic one. 

Again this is not an EMS replacer, only basic EMTs here!
