4.2.4 Military aviation capabilities Military aviation capabilities consist of the capabilities for air operations, air support, and aviation education and training. These capabilities will support air transport, provide protection to the Republic of Slovenia’s airspace, and support the Slovenian Armed Forces’ units. Emphasis will be on joint combat operations within the Slovenian Armed Forces, and on joint operations within the Alliance. Military aviation capabilities will be deployable within the Alliance’s territory, and partly deployable outside it. The establishment of new capabilities will follow the principle of reducing the number of different types of aircraft, and the principle of their multi-purpose use. Efforts will also be directed towards the establishment and provision of medium-range air transport capabilities. Air surveillance by interceptor aircraft (air policing) will take place within NATO. 19
