In relay pumping, which pumper ends up delivering pressurized water to the fire scene?

Explanation:
In relay pumping, water is moved from a source through a chain of pumpers, with each pumper helping to maintain or increase pressure along the supply line. The pumper stationed at the fire scene that actually feeds the handlines and pushes water through the nozzle is the attack pumper. The source pumper sets the water supply in motion and starts the pressurization, while the relay pumpers keep the pressure up as the line grows longer. The support pumper adds additional water supply as needed, but it’s the attack pumper at the scene that delivers the pressurized water to the hose and nozzle.
