Casualty classification

The casualty classification is a way to determine the status military personnel.

List of classifications

 * KIA - Killed In Action. This term is used when a military combatant is killed during battle, or deaths resulting from a war.
 * MIA - Missing In Action. This term is used when the status of a military combatant is unknown, whether they're dead, wounded, or simply lost.
 * POW - Prisoner Of War. This term is used for anybody, including soldiers who are captured as part of a war. A medal is awarded to any military combatant who is captured for any length of time and has either escaped or was rescued.
 * WIA - Wounded In Action. This term is used when a military combatant is severely injured in battle, rendering them either temporarily or permanently unable to continue active duty.

Trivia
Due to the need to increase morale in the UNSC, SPARTAN-II and SPARTAN-III supersoldiers are never listed as 'Killed In Action', but rather as 'Missing In Action' or 'Wounded in Action' to give the appearance that they are invincible.
