Which type of wildland fire apparatus is designed to transport water to the scene of a wildland fire?

The type of wildland fire apparatus that is specifically designed to transport water to the scene of a wildland fire is a water tender. Water tenders are equipped with large water tanks and are essential in providing a reliable water supply, especially in remote areas where hydrants may not be available. They can carry significant amounts of water, allowing firefighters to establish a water supply for firefighting operations in wildland fire situations.

In contrast, structural apparatus typically refers to fire trucks designed for urban environments, focusing more on transporting firefighters and equipment, rather than primarily acting as water carriers for wildland fires. Brush trucks are specialized vehicles designed for wildland firefighting, often equipped with smaller tanks, pumps, and the ability to navigate rough terrain, but their main purpose is to combat fires rather than just transport water. Lastly, a tiller is a type of apparatus maneuvered by a second operator at the rear, used primarily for urban settings, and does not fulfill the specific role of transporting water to wildland fire scenarios. Thus, the answer aligns perfectly with the intended function of each type of apparatus in relation to wildland firefighting.
