Medical ships and craft other than those referred to in Article 22 of this Protocol and Article 38 of the Second Convention shall, whether at sea or in other waters, be respected and protected in the same way as mobile medical units under the Conventions and this Protocol. Since this protection can only be effective if they can be identified and recognised as medical ships or craft, such vessels should be marked with the distinctive emblem and as far as possible comply with the second paragraph of Article 43 of the Second Convention.
