As it stands, more than 55,000 active-duty U.S. soldiers – wracked by war wounds and injuries – are deemed non-deployable. In 2018, more than half of all active-duty soldiers sustained some form of physical trauma – with over 70% diagnosed as lower extremity micro-traumatic musculoskeletal (MSK) or "overuse" injuries.
And aside from the gaping hole it leaves in the defense and security arena, the medical costs related to MSK ailments across all military branches cost the U.S.
taxpayer more than $575 million per year. The U.S Marines using the Sparta Science system were taken at the School of Infantry – West Training Command at MCB Camp Pendleton, California.
