Which fire apparatus must have a pump, water tank, fire hose storage, aerial, and ground ladders?

The quint is designed to combine the functionalities of a pumper and an aerial device into a single fire apparatus. This means it is equipped with a pump for supplying water, a water tank to store that water, and fire hose storage to carry hoses needed for firefighting operations. Additionally, a quint comes with both aerial ladders for reaching higher elevations during rescue operations or for access in firefighting, as well as ground ladders for rapid deployment in various situations.

The engineering of a quint allows it to serve multiple roles at an incident scene effectively, which is beneficial for smaller departments that may not have the resources to maintain multiple specialized units. It embodies the versatility needed in modern firefighting operations, making it a valuable tool for any fire department.

In contrast, while a pumper also has a pump, water tank, and hose storage, it lacks the aerial capabilities. Mobile water supply units focus primarily on transporting large quantities of water without the other necessary firefighting equipment, and aerial apparatus is primarily designed for elevation but does not typically carry a water tank or the same complement of ground ladders as a quint.
