Anyone who has ruck marched with a heavy pack, performed a parachute landing fall out of a C-130 or worn body armor all day knows that the military lifestyle is rough on the body. Due to the physical requirements of the military, veterans experience a much higher rate of chronic pain than the civilian population. The recent wars in Iraq and Afghanistan have led to more advanced body armor, saving the lives of thousands of soldiers, Marines, sailors and airmen. These advances in equipment, though lifesaving, mean that troops survive with devastating injuries such as limb amputations and traumatic brain injury that require advanced, coordinated treatment.
