Practice Relating to Rule 143. Dissemination of International Humanitarian Law among the Civilian Population
The US Field Manual (1956) reproduces Article 47 of the 1949 Geneva Convention I, Article 48 of the 1949 Geneva Convention II, Article 127 of the 1949 Geneva Convention III and Article 144 of the 1949 Geneva Convention IV.
The US Air Force Pamphlet (1976) quotes a directive of the Department of Defense which provides:
The Armed Forces of the United States will insure that programs to prevent violations of the law of war to include training and dissemination as required by the  Geneva Conventions … and by [the 1907] Hague Convention IV … are instituted and implemented.
The Pamphlet adds that “all states must include the text of the Conventions in programs of … if possible, civil instruction”.
At the 27th International Conference of the Red Cross and Red Crescent in 1999, the United States pledged that “the United States will work to broaden and enhance efforts for dissemination of IHL, including in co-operation with the American Red Cross”.
