Material resources ensure the degree of equipment procurement stipulated in the NATO Capabilities Code, in accordance with the type of structure nominated for each capability separately. In the process of rendering operational the military structures, the planned level of readiness will be achieved through revitalization, redistribution, and functionality maintenance of the current equipment, and through the acquisition of new equipment by involving the Romanian defense industry in providing the products and services required by the Romanian Armed Forces. The major procurement programs will include planning and acquisition of the elements of integrated logistic support to ensure sustainability of equipment throughout its entire life cycle. Maintenance for military equipment will be provided mainly within our own structures trough supplies of spare parts and materials, testing and support equipment, personnel training, technical documentation and specific infrastructure, in facilities offered by the national defense industry and/or in framework of cooperation offered by NATO and the EU. Technological and research resources will provide the basis for the modernization of military equipment in order to develop the capabilities required by the Romanian Armed Forces to carry out its national defense missions according to established directions. CHAPTER 6 - STRATEGIC AND OPERATIONAL PRINCIPLES AND CONCEPTS Military strategy defines strategic and operational principles and concepts which ensure the accomplishment of national military objectives and missions. Maintaining their elements of continuity in ensuring the defensive-active character of Romania’s Military Strategy, the strategic concepts regarding a credible defensive capacity, restructuring and modernization, and the enhanced operational partnership remain valid for the timeframe 2016-2019 with adjustments in actions according to the directions stipulated in the present strategy. The use of the element of military power to defend and promote national interests will be based on the following strategic principles: legitimacy, unity of action in an allied context, multidimensional interdependence, joint and interagency action, flexibility, strategic initiative, and proportionate response. Legitimacy is provided by having the Romanian Armed Forces exclusively under the will of the people and the conduct of any action only within a legal national and international framework. The use of force will observe the legal, moral, ethical, political, and diplomatic norms, and ensure the accomplishment of military objectives and missions. The principle of unity of action in an allied context is achieved in accordance with Romania’s status as a member of NATO and the EU and with the participation of the Romanian Armed Forces in collective defense/ mutual assistance clause through a coherent approach to threats. The wide range of unconventional and asymmetric risks and threats, and the diversification of the types of crises and conflicts require an interdependent and multidimensional approach of threats, risks, and vulnerabilities and a joint, interagency response in hostile operational environments, in difficult geo-climate conditions by configuring a force structure adequate to the mission. According to the type, duration, and complexity of the missions, the Romanian Armed Forces develop and engage adequate capabilities, which are task-organized in a modular manner according to the principle of flexibility, in order to accomplish the full range of missions. Strategic initiative ensures competitiveness over time of the military and its purpose is to define the conceptual framework and implementation of defense policy objectives, 17
