IV. CAPABILITIES DEVELOPMENT 5 According to the Joint Doctrine of the Armed Forces of the Republic of Croatia, based on NATO doctrinaire postulates, the following capability elements of the Armed Forces are defined: doctrine; organization; materiel; personnel; management; infrastructure; education and training. In each of these basic elements of capability there is interoperability, i.e., a possibility of joint actions with Allied forces. Possessing and developing relevant capabilities is a prerequisite of successful accomplishment of the Armed Forces missions and tasks. Dynamic security environment characterized by series of hardly predictable specific threats and challenges considering form and effectiveness together with a low degree of possibility of a traditional threat by armed aggression, determines the approach to the capability based planning of the Armed Forces development. Successful response to a threat or challenge requires capabilities that are tailored and built with regards to types and the nature of threats or challenges and act accordingly. Since the acquiring of the capabilities is accomplished by means of organization and other elements of capabilities5, the requirements that define the capabilities direct all aspects of organization and development of the Armed Forces. Capabilities that the Armed Forces should possess and develop are to be considered through seven main areas: 1. Prepare, 2.  Communications, command and control (C3), 3. Project, 4. Engage, 5. Inform/Situational Awareness, 6. Logistics and Sustain, 7. Protect. Prepare Preparation comprises capabilities needed for continuous improvement of effectiveness, before and during operations. The following types of capabilities will be developed: • Defense Planning Capability will be continually enhanced and will follow processes of Strategic Planning in the Republic of Croatia. National Defense Planning will be harmonized with processes within the system of NATO Defense Planning; • The achieved level of capability regarding the evaluation of forces and capability review will be maintained in order to ensure effective mechanisms of feedback information in the process of developing capabilities at the national and international level and to ensure interoperability of the NATO and EU declared forces; • The achieved level of training and exercise will be improved in order to ensure a higher degree of integrity of other capability elements and to continue with validation of the achievements regarding required capabilities; • Capabilities of generating forces will be improved as well as timely force availability through the better planning of the use of the Armed Forces, relevant equip- T H E C R O AT I A N A R M E D F O R C E S L O N G − T E R M D E V E L O P M E N T P L A N 2 0 1 5 − 2 0 2 4
