Prisoner-of-war status or treatment also covers various categories of people who do not come under the definition of combatant, but are entitled to prisoner-of-war status:
A. those taking part in a levée en masse, that is, the inhabitants of an unoccupied territory who spontaneously take up arms, on the approach of the enemy, to resist the invading forces, without having had time to form themselves into regular armed units, provided that they carry arms openly and respect the laws and customs of war.
