because they are any person to capture or internet by a Belligerent power during war
A prisoner of war (POW) is a person, whether a combatant or a non-combatant, who is held captive by a belligerent power during or immediately after an armed conflict. The earliest recorded usage of the phrase "prisoner of war" dates back to 1660.
Belligerents hold prisoners of war in custody for a range of legitimate and illegitimate reasons, such as isolating them from enemy combatants still in the field (releasing and repatriating them in an orderly manner after hostilities), demonstrating military victory, punishing them, prosecuting them for war crimes, exploiting them for their labour, recruiting or even conscripting them as their own combatants, collecting military and political intelligence from them, or indoctrinating them in new political or religious beliefs.
