How many Light and Air Units are operational in the department?

The number of Light and Air Units operational in the department is one. These units play an essential role in emergency operations, particularly during incidents that require illumination or air supply, such as extended firefighting operations or rescue missions. Having one unit allows for a focused resource that can be rapidly deployed to enhance safety and efficiency on the scene.

While the other options suggest a greater number of units, the operational capacity and resource management typically reflect the necessary support structures without redundancy. It's crucial for departments to optimize their resources while ensuring they can effectively respond to varied incidents. Understanding this operational setup is important for recognizing how support units integrate into overall fire and rescue operations.
