Practice Relating to Rule 142. Instruction in International Humanitarian Law within Armed Forces
Mexico’s Army and Air Force Manual (2009) states:
The publication of this manual by the Ministry of National Defence of Mexico contributes to fulfilling the obligation undertaken by the Government of Mexico on signing the  Geneva Conventions to ensure that these instruments are disseminated as widely as possible in both peacetime and wartime and that their study is incorporated into the military instruction and training system, so that the members of the armed forces are familiar with the principles enshrined in them.
The High Command, which is responsible for organizing, managing, preparing, educating, instructing, training and developing the land and air forces, has taken the steps necessary to ensure that the members of these forces are aware of their obligations under the above-mentioned Conventions, with a view to preventing violations of the provisions of international humanitarian law.
In a section on the 1949 Geneva Convention II, the manual also states:
The High Contracting Parties undertake, in time of peace and in time of war, to disseminate the text of the Convention as widely as possible in their respective countries, and, in particular, to include the study of the Convention in their programmes of military … instruction, so that the principles that it contains may become known … to the armed forces.
