Indonesia’s future Threats, Disturbances, Obstacles and Challenges (TDOC) are nonconventional. Indonesia’s defense paradigm if relying only on the TNI as a major force should be changed. The drastic reduction of the military threats (conventional) from other countries to Indonesia, as well as similar threats around the world, make us have to rethink how the most appropriate formulation of Indonesia’s defense strategy in this era of non-military threats. To that end, the formation of reserve components, previously equipped with competent and knowledgeable knowledge of civic defense, needs to be considered. The consideration is that the formation of this reserve component can be useful as a major defense element supporting the main component, primarily to deal with non-military threats. The use of reserve components is not only prepared for war, but has a primary function of helping TNI deal with TDOC that is non-physical (intangible). This paper will discuss how the reserve component, as part of the nation’s defense force, faces future non-military threats. In addition, this paper also sees that civic defense can be an integral part of the effort of the reserve component to make this happen.
