Which two unit types best describe a fire engine and an ambulance?

• A. Fire Department, Rescue
• B. Primary, Secondary
• C. Firefighter, Paramedics
• D. First, Necessary

Answer: (B)

Unit type classifications in dispatch use Primary for the main responding resource and Secondary for back-up or support resources. The fire engine is the core asset for firefighting tasks, so it is the primary unit. The ambulance provides medical care and transport as needed and often serves to support the incident after the initial suppression, making it a secondary unit. Other options describe agencies, roles, or phrases that aren’t used as unit-type designations. So Primary and Secondary is the best description for a fire engine and an ambulance.
