Traumatic Brain Injury (TBI) is the

Signature Wound of the Global War on Terror

Special Operations are more than two times as likely to sustain a TBI as conventional forces.

Special Operations Forces are more than twice as likely to sustain a traumatic brain injury as conventional forces.

The average wait time for SOF personnel to receive TBI rehabilitation: 1,746 days from injury.
