What type of helicopters are considered specialized air ambulances?

Specialized air ambulances are defined by their specific design and equipment tailored for medical transport. Helicopters classified in this category are equipped with advanced medical technology, like patient monitoring systems, emergency medical equipment, and space for medical personnel to attend to patients during transit. This specialization allows for efficient and effective transport of critically ill or injured patients, ensuring they receive necessary care while en route to medical facilities.

The other options do not fully align with the requirements for specialized air ambulances. Military helicopters, while capable of serving various purposes, are not exclusively designed for medical transport. Similarly, helicopters used for tourism are primarily meant for recreational purposes and lack the necessary medical equipment and setup. Multi-purpose utility helicopters, although versatile, do not specifically cater to the medical transport needs that define specialized air ambulances.
