Aren't (many?) firefighters certified as paramedics?

In USA, most are not paramedics (ALS). Those are typically only advanced-care ambulances (blood, drugs, intubation, EKG/manual defib, emergency operations like trach tubes). But a lot of firefighters are EMTs (BLS). Oxygen, vent bags, aspirin, Epipen, CPR, automated defib (AED).
