Why is extremity hemorrhaging considered the leading cause of death on the battlefield?

Extremity hemorrhaging is considered the leading cause of death on the battlefield primarily because it is not protected by body armor. Body armor typically covers vital organs located in the torso, which leaves the extremities, such as arms and legs, exposed. Wounds to these areas can lead to significant blood loss, which, if not controlled quickly, can result in shock and death.

The nature of battlefield injuries often results in severe bleeding from extremities, especially during combat scenarios where high-velocity projectiles or shrapnel can cause catastrophic injuries. Unlike torso injuries that might be mitigated by protective gear, extremity injuries can result in immediate life-threatening conditions due to the potential for rapid blood loss. Therefore, managing extremity hemorrhaging swiftly with techniques such as tourniquets is critical to improving survival chances in combat situations.
