What is the recommended action to take before moving a casualty in the Care Under Fire phase?

In the Care Under Fire phase of Tactical Combat Casualty Care (TCCC), the highest priority is to control life-threatening bleeding before moving a casualty. Applying a tourniquet to a limb with severe bleeding is a crucial action that can drastically increase the casualty's chances of survival. This phase emphasizes care provided under active threat conditions, where the immediate environment is still dangerous. Therefore, stabilizing the casualty by stopping significant blood loss is essential before any other intervention or movement can be safely considered.

While airway management and other interventions are important in patient care, they are secondary to controlling severe bleeding during this critical phase. In contrast to options focusing on airway issues or other procedures, the application of a tourniquet directly addresses the most immediate and life-threatening condition, aligning with the protocols established for combat scenarios.
