What is an advantage of a one-person drag/carry method?

The correct answer reflects a scenario where a one-person drag or carry method indeed exposes less of the rescuer to enemy or hostile fire. This advantage is particularly significant in tactical situations where every moment counts, and exposure to potential threats must be minimized. By allowing one individual to perform the drag or carry, it reduces the overall profile of the team in a dangerous environment, making them less visible and therefore less likely to attract enemy attention.

In addition, the question's context indicates that efficient use of personnel in combat situations is crucial for survival and success. When only one person is engaging in the carry, they can maintain a lower posture, move more quickly, and potentially keep their eyes on the surroundings more effectively compared to a scenario where more individuals are involved and exposed. While communication might be simpler in some circumstances when fewer people are engaged, the trade-off in terms of safety and exposure in a combat zone makes the one-person carry method particularly advantageous.

Maintaining stealth and reducing the target area is critical in tactical operations, underlining why the ability for a single rescuer to move with a casualty is a strategic advantage.
