What method is most effective for transporting multiple casualties?

Utilizing vehicles designed for mass transport is the most effective method for transporting multiple casualties because it significantly increases efficiency and speed in evacuating individuals from a scene. This approach allows for a larger number of casualties to be moved simultaneously, which is crucial in emergency situations where time is of the essence and medical attention is immediately needed.

Mass transport vehicles are equipped to handle various logistical challenges, such as providing protection, space for medical equipment, and ensuring that casualties are secured during transit. This method minimizes the physical strain on medical personnel and optimizes the use of available resources. Additionally, vehicles can traverse rough terrain more easily than individuals on foot, thus reducing transit time and increasing the likelihood of maintaining the casualties' conditions during transport.

In contrast, using individual stretchers for each casualty would require more manpower and time, making it inefficient when dealing with a high volume of casualties. Carrying them on foot might work in certain contexts, but would also be slower and less stable. Grouping casualties in pairs, while it may seem practical, does not maximize capability as effectively as using a vehicle designed for mass transport, where injuries can be monitored and treated en route.
