Article 85 entitled “Principle of Humanity”, contained in Title IV on Operations [of the Royal Ordinances for the Armed Forces (2009)] clearly embodies the spirit of the [1949] Geneva Convention and its [1977] Additional Protocols, as it provides that “[the] … conduct [of members of the armed forces] in any conflict or military operation must conform to the applicable rules of the international treaties on international humanitarian law to which Spain is a party”.
That is further developed in Chapter VI on Ethics in Operations, which goes into specific duties under international humanitarian law … the principle of the distinction between civilians and combatants.
