Cartel aircraft: An aircraft used by a parlementaire sent to parley with the enemy. A cartel aircraft enjoys the same conditional immunity as the parlementaire.
Cartel ship: A ship used by a parlementaire on a mission to the enemy. The cartel ship has the same immunity as the parlementaire. It may also be used to transport prisoners of war and wounded to be exchanged with those of the enemy. The ship must bear the appropriate distinctive sign and its route must be known. It may not be armed and may not be attacked or captured during the outward or return voyage.
