The Annales de droit international médical (No. 11, 1964) includes an article written jointly by a Colonel, Dr. A. Guérisse and two Doctors of Laws, Mr. A. Jacquemin and Mr. G. Kellens. The title is “The Armed Forces of the United Nations and their Humanitarian and Medical Mission”. Consideration is first given to what the United Nations Armed Forces are, what were the reasons for their organization and in what circumstances they have been called upon to act. The authors then explain the need for the attachment of a medical service to these armed forces and, in a chapter of which the main substance is reproduced below, they analyse the problem of the application of the Geneva Conventions by the U.N. forces.
