Wounded in action (WIA)
Wounded in action (WIA) – a battle casualty who has incurred a non-fatal injury due to an external agent or cause as a result of hostile action.
Typically, it implies that they are temporarily or permanently incapable of bearing arms or continuing to fight. Generally, the Wounded in Action are far more numerous than those killed. Common combat injuries include second and third-degree burns, broken bones, shrapnel wounds, brain injuries, spinal cord injuries, nerve damage, paralysis, loss of sight and hearing, post-traumatic stress disorder (PTSD), and limb loss. For the U.S. military, becoming WIA in combat generally results in subsequent conferral of the Purple Heart because the purpose of the medal itself (one of the highest awards, military or civilian, officially given by the American government) is to recognize those killed, incapacitated, or wounded in battle [Wikipedia].
A casualty category applies to a hostile casualty, other than the victim of a terrorist activity, who has incurred an injury due to an external agent or cause. The term encompasses all kinds of wounds and other injuries incurred in action, whether there is a piercing of the body, as in a penetration or perforated wound, or none, as in the contused wound. These include fractures, burns, blast concussions, all effects of biological and chemical warfare agents, and the effects of exposure to ionizing radiation or any other destructive weapon or agent. The hostile casualty's status may be categorized as "very seriously ill or injured," "seriously ill or injured," "incapacitating illness or injury," or "not seriously injured" [The Free Dictionary].
