Scholars have analyzed participation by civilians in defense ministries in Latin America from a dual perspective: as part of a civilian-military integration and as an instrument of civilian control of the sector. These practices have been adopted in a context of democratic consolidation and, in the governmental sphere, of a demand for rationalization and greater efficiency and effectiveness in the conduct of government. The case of Chile is a good example of this. Since the restoration of democracy (1990), the inclusion of civilians in the Ministry has been a constant. All of the ministers have been civilians, as have all undersecretaries; however, because the Ministry does not have a permanent staff of civilian professionals, an Advisory Committee has gradually and inorganically developed within the Ministry, which brings in people who provide advisory services on political, politico-strategic, budgetary, international, communications and auditing issues.
