What is referred to as an individual vehicle and its assigned personnel?

The term "single resource" specifically refers to an individual vehicle and its assigned personnel, which can include emergency services like fire, medical, or rescue units. In the context of rescue operations, a single resource is utilized to describe one specific asset fully equipped and staffed to handle tasks at an incident scene. This concept distinguishes a singular unit working independently as opposed to collective groups or teams.

The other options represent different structures in emergency response. An operational unit could refer to a larger collective range of resources working together, while an incident team typically implies a coordinated group that may encompass multiple single resources aimed at managing the entire incident. A sector resource, on the other hand, would indicate a unit assigned to operate within a specific area of an incident, which may include several single resources. Thus, referring to an individual vehicle and its assigned personnel as a single resource succinctly captures its distinct and self-sufficient nature in operations.
