An apparatus equipped with a fire pump, water tank, hose, aerial device, and ground ladders is commonly referred to as a:

The correct choice is a Quint. A Quint is a type of fire apparatus that combines the functions of a fire engine and a ladder truck. It is specifically designed to provide both fire suppression capabilities and aerial access when necessary. The key features of a Quint include an onboard fire pump, a water tank, hoses for firefighting, an aerial device (usually a ladder or platform), and ground ladders for various firefighting and rescue operations. This multifunctionality allows Quints to perform a wide range of tasks at emergency scenes, making them versatile pieces of equipment in fire service operations.

While an engine refers primarily to apparatus focused on pumping water and providing hose lines, and a ladder truck specializes in aerial operations, the Quint uniquely integrates the essential features of both. Rescue vehicles typically lack the aerial capability and extensive water supply features that a Quint possesses, further distinguishing the role and utility of Quints within a firefighting fleet.
