While under enemy fire, which action can you perform before moving the casualty to safety?

Applying a tourniquet is a critical and time-sensitive action that can be performed before moving a casualty to safety, especially when there is severe bleeding that poses an immediate threat to life. The application of a tourniquet can effectively control life-threatening hemorrhage from an extremity, allowing for better chances of survival while reducing the risk of further blood loss during evacuation.

In high-stress environments, such as under enemy fire, rapidly stopping major bleeding takes precedence over other interventions. By prioritizing this action, the focus remains on stabilizing the casualty to prevent exsanguination before securing a safe environment for further medical care or evacuation.

Other actions, like administering CPR, managing the airway, or dressing a wound, may require more time and a stable environment to be performed effectively. In particular, performing these procedures may be complicated or ineffective while still under enemy fire, where immediate safety and stabilization of hemorrhage are paramount.
