What is an advantage of a 2-person supporting carry?

The advantage of a 2-person supporting carry is that it can be employed to transport both conscious and unconscious casualties effectively. This method allows two individuals to support a casualty in a way that provides stability and helps distribute weight evenly.

In situations where the casualty is conscious, they can assist by following instructions and holding on to the carriers, making the transport smoother and leveraging the capability of the rescuers. Conversely, when dealing with unconscious casualties, the 2-person supporting carry ensures that the casualty remains secure and less prone to further injury during the transport process. This adaptability enhances the overall ability of medical personnel to evacuate and manage casualties in various states of consciousness, which is crucial in emergency medical situations.

The other options don't provide a broader advantage as they either limit the types of casualties that can be transported or imply the need for specialized equipment, which isn't necessary for this type of basic carry. Although it is essential to have protocols for transporting injured individuals, the defining characteristic of the 2-person supporting carry is its versatility in accommodating casualties regardless of their level of consciousness.
