Mexico’s Army and Air Force Manual (2009), in a section on the 1949 Geneva Convention II, states: “After each engagement, parties to the conflict must take all possible measures to … protect [the shipwrecked, wounded and sick] against pillage and ill-treatment”. 

Mexico’s Code of Military Justice (1933), as amended in 1996, provides penalties for persons who mistreat or otherwise cause physical or mental injuries to the wounded and sick.
