Missing in action

Military term describing someone reported missing during service

Missing in action (MIA) is a casualty classification assigned to combatants, military chaplains, combat medics, and prisoners of war who are reported missing during wartime or ceasefire. They may have been killed, wounded, captured, executed, or deserted. If deceased, neither their remains nor grave have been positively identified. Becoming MIA has been an occupational risk for as long as there has been warfare.
