Up to now there has been no multinational or joint doctrine in Latin America for the participation of its armed forces in United Nations peacekeeping operations. However, most of the countries are actively participating in peacekeeping operations, as part of multinational contingents, such as the MINUSTAH. As the result of this situation, there has arisen a need for developing a common doctrine for the employment of military and police forces and civil contingents in this type of operation. This article presents a brief description of the three existing doctrinal models: UN, NATO and USA, with a critical analysis of the challenges that arise in generating a unique model adapted to Latin American realities.
