Field Manual FM 27-10 MCRP 11-10B.2 Formerly MCRP 5-12.1B Treaties Governing Land Warfare 2 May 2016 This pamphlet is intended to serve as a supplement to FM 27-10, The Law of Land Warfare, 18 July 1956. The principal international conventions referred to therein are here given in the full English text. It should be noted, however, that the only official text of the Hague Conventions of 18 October 1907 is the French text which must be consulted and accepted as controlling in the event of a dispute as to the meaning of any provision of these particular conventions. The Geneva Conventions for the Protection of War Victims of 12 August 1949 have been ratified by the United States and came into force for this country on 2 February 1956. The effect of these four conventions upon prunus treaties to which the United States is a party is discussed in detail in paragraph 5, FM 27-10. Each of the earlier Geneva Conventions of 1864, 1906, and 1929 and each of The Hague Conventions of 1899 and 1907 will, of course, continue in force as between the United States and such of the other parties to the respective conventions as have not ratified or adhered to the respec-tive superseding convention(s) governing the same subject matter. 11oreover, the United States has adopted the policy of observing and enforcing the tern1s of the 1929 Geneva Convention related to the Treatment of Prisoners of War and the 1907 Hague Conventions, both of which have been held declaratory of the customary law of war to which all States are subject, in so far as such Conventions are not superseded by the 1949 Geneva Conventions which necessarily govern the relations between the parties to the latter. (See pars. 6 and 7, FM 27-10.) As the essential provisions of the earlier Geneva Conventions and Hague Conventions mentioned above have been substantially incor-porated into the more recent and more comprehensive conventions on the same subject matter, observance of the later conventions will usually include observance of the former. For this reason, only the more recent 1949 Geneva Conventions and those Hague Conventions relating to land warfare which have not been entirely superseded have been reproduced in this pamphlet. Pertinent information concerning the current status of ratifications, adherences, reservations, and denunciations (withdrawals) will be transmitted by higher authority to commanders in the field as occasions arise, thus rendering unnecessary the inclusion of such data in this pamphlet and avoiding the frequent changes that such inclusion would entail.
