According to TCCC, what is the leading cause of preventable death on the battlefield?

The leading cause of preventable death on the battlefield is attributed to bleeding. In tactical combat situations, traumatic hemorrhage can occur from various types of injuries, leading to significant blood loss. It is essential to identify and control this bleeding quickly, as rapid hemorrhagic shock can develop, significantly increasing the risk of mortality. TCCC emphasizes the importance of early intervention techniques such as applying tourniquets, hemostatic dressings, and proper positioning to manage severe bleeding effectively.

While burns, traumatic brain injuries, and pneumonia are serious conditions that can certainly contribute to morbidity and mortality, they are not as immediate or as directly impactful on survival in the acute battlefield context as uncontrolled bleeding. This understanding is vital for any combat lifesaver, as prompt action to control bleeding can mean the difference between life and death in the field.
