Bounding overwatch ensures one element covers while another moves, providing suppressive fire and security for litter teams. This prevents ambush and protects casualties during evacuation. Speed alone cannot guarantee survivability without security. It does not replace medical care or HLZ marking. Bounding integrates tactical and medical priorities, ensuring mission continuity and casualty survival under hostile conditions.

Flail chest results from multiple rib fractures creating a paradoxically moving segment and impaired ventilation. Initial management includes stabilizing the segment (bulky dressing, manual pressure or commercial devices), providing oxygen, and giving analgesia to improve ventilation mechanics. Needle decompression is for tension pneumothorax, which is not suggested by bilateral breath sounds and no rising hemodynamic compromise. Cricothyrotomy is for airway obstruction/failure to ventilate/oxygenate. Hyperventilation offers no benefit and may worsen respiratory fatigue. Monitor closely for deterioration—underlying pulmonary contusion can evolve, potentially requiring positive pressure ventilation at higher care. Continue hypothermia prevention and manage other MARCH priorities.

A CCP must balance casualty care with tactical security. A defensible position with cover, concealment, and multiple exit routes is safest. Open areas, rooftops, and crowded markets increase vulnerability to follow-on attacks. Proper CCP selection ensures casualty flow, triage, and evacuation occur with minimal risk. Alternate CCPs must also be preplanned, with rehearsals to facilitate rapid displacement if conditions deteriorate.

Studies from past conflicts show extremity hemorrhage is the number one preventable cause of death. Tourniquet use, wound packing, and hemostatic dressings directly reduce this mortality. Tension pneumothorax and airway obstruction are also major causes but less common. Hypothermia contributes to mortality but is rarely sole preventable cause. Recognizing this data drives the emphasis on rapid bleeding control during Care Under Fire. Modern tactical training prioritizes tourniquet application proficiency and immediate recognition of catastrophic hemorrhage.

TCCC/TECC guidelines emphasize resource preservation in austere, tactical environments. In casualties with no signs of life after penetrating/blast trauma (no breathing, pulse, or purposeful movement), resuscitation is not initiated. CPR in combat zones exposes rescuers, diverts resources, and has virtually no survival in this setting. Exceptions may exist for hypothermia, drowning, or electrocution. Otherwise, focus on living casualties with salvageable injuries. Ethical, tactical, and medical priorities converge in this difficult decision.
