In Tactical Combat Casualty Care, what is the correct MARCH priority order?

• A. Massive hemorrhage, Airway, Respirations, Circulation, Hypothermia/Head Injury
• B. Airway, Massive hemorrhage, Respirations, Circulation, Hypothermia/Head Injury
• C. Massive hemorrhage, Respirations, Airway, Circulation, Hypothermia/Head Injury
• D. Massive hemorrhage, Airway, Circulation, Respirations, Hypothermia/Head Injury

Answer: (A)

In Tactical Combat Casualty Care, the sequence prioritizes actions that save the most lives first: massive hemorrhage control comes first because uncontrolled bleeding is the most immediate threat to survival on the battlefield. Once bleeding is controlled, securing the airway is next to ensure the patient can oxygenate and ventilate, since airway compromise rapidly becomes lethal. After the airway, treat respiration to optimize breathing and manage chest injuries or ventilation problems. Next comes circulation, focusing on maintaining perfusion and continuing hemorrhage control and resuscitation as needed. Finally, address hypothermia prevention and head injury management, which are important but not as time-critical as stopping bleeding and ensuring airway, breathing, and circulation.
