What is one of the capabilities of the FAWPSS?

The correct answer highlights one of the capabilities of the FAWPSS, which stands for the Forward Area Water Point Supply System. This system is specifically designed to support small unit water requirements, particularly in situations where traditional ground supply routes are unavailable. By providing necessary hydration directly to field units, the FAWPSS enhances operational effectiveness and sustainment in combat scenarios, where access to water can be critical.

The other options do not accurately represent the FAWPSS's primary functions. For instance, while desalination capabilities are important, the FAWPSS is not primarily tasked with purifying saltwater for drinking purposes. Similarly, while air transport is a valuable asset in military logistics, the primary role of the FAWPSS does not involve providing airlift support for large units; this typically falls under different logistical systems. Finally, the claim of providing an unlimited water supply is unrealistic, as the FAWPSS is designed to support immediate and tactical water needs, rather than serving as an endless source for strategic operations.
