Killed in action

Killed in action (KIA) is a casualty classification generally used by militaries to describe the deaths of their own forces at the hands of hostile forces. The United States Department of Defense, for example, says that those declared KIA need not have fired their weapons but have been killed due to hostile attack. KIAs do not come from incidents such as accidental vehicle crashes and other "non-hostile" events or terrorism. KIA can be applied both to front-line combat troops and to naval, air and support troops
