What is true about the nurse tanker operation?

The nurse tanker operation is designed to enhance the efficiency of water supply at incidents by enabling Mobile Water Supply (MWS) apparatuses to dump water into independent tanks. This method allows for the storage of water closer to the scene, enabling quicker access and reducing the need for continuous tanker trips back to a water source. By utilizing these independent tanks, firefighters can maintain a steady supply of water for ongoing operations, improving their ability to manage fire suppression efforts effectively.

The other options do not accurately reflect the nature of nurse tanker operations. While it is one of several methods to supply water, it is not the only option available. The efficiency of transporting water can vary based on the scenario, and asserting that no pumps are needed overlooks the potential use of pumps in various MWS configurations.
