If a casualty cannot apply self-aid after being shot in the chest, what should be done in the Care Under Fire phase?

In the Care Under Fire phase, the primary focus is on the safety of both the casualty and the rescuer, as it occurs in a potentially hostile environment. If a casualty cannot apply self-aid after sustaining a gunshot wound to the chest, moving them to cover is essential. This action helps to protect the casualty from ongoing threats and allows for a more secure environment to provide further medical assistance.

Once the casualty is in a safer position, additional measures can then be taken, such as controlling bleeding or applying a chest seal. However, the immediate priority during this phase is to ensure that both the casualty and the rescuers are safe from any further harm. Other choices, while important in later stages of care, may not be feasible or safe to perform if the area is still under threat. Thus, moving the casualty to cover is the most appropriate initial action to take.
