Approximately 90 percent of combat casualty deaths occur before the casualty reaches a higher level of care (surgeon, etc.).

Prehospital care, including the care provided by CLS, is critical to the survival of those wounded in combat.

Multiple research studies and casualty data from Iraq and Afghanistan highlight the causes of preventable death on the battlefield.

TCCC training focuses on identifying and treating these most common causes of preventable death on the battlefield: hemorrhage/bleeding, injuries resulting in tension pneumothorax, and airway issues.
