In the western US, what term is used for automotive water supply apparatus used in wildland firefighting?

In the context of wildland firefighting in the western United States, the term "tender" specifically refers to an automotive water supply apparatus designed to transport and supply water to the firefighting site. Tenders are typically equipped with large tanks that carry a significant amount of water, allowing firefighters to quickly access water in areas where fire hydrants are not available, such as remote or rural locations. This makes tenders essential for effective wildfire containment efforts.

The other terms, while related to water transportation, may not accurately convey the intended use in wildland firefighting. For instance, "water truck" and "tank truck" can refer to vehicles used for various purposes, including municipal water supply. "Tanker" generally describes a broad category of vehicles designed to transport liquids but may not always be used specifically for firefighting scenarios. In the wildland firefighting context, "tender" clearly signifies a vehicle purpose-built for delivering water to fight wildfires.
