Practice Relating to Rule 1. The Principle of Distinction between Civilians and Combatants
Section B. Attacks against combatants
Mexico’s Army and Air Force Manual (2009) states:
The underlying idea of this body of law [i.e. IHL] is to humanize war. The three main principles established to this end … [include]:
A. military operations may only be directed against combatants.
Mexico’s IHL Guidelines (2009), in a section titled “Basic rules of conduct in armed conflict”, states: “Fight only enemy combatants”.
At the CDDH, Mexico stated that it believed Article 47 of the draft Additional Protocol I (now Article 52) to be so essential that it “cannot be the subject of any reservations whatsoever since these would be inconsistent with the aim and purpose of Protocol I and undermine its basis”.
