 Beginning in 1961, the Directorate of Military Training took charge the research for national defence planning, military doctrine and strategy for both internal and external threats.This included reviews of international and domestic political situations, studies of the potential sources of conflicts, collection of information for strategic planning and defining the possible routes of foreign invasion.In 1962, as part of new military doctrine planning, principles of anti-guerrilla warfare were outlined and counterinsurgency-training courses were delivered at the training schools.
