Air defence capabilities will be based on modern short- to medium-range mobile systems. They will provide direct and indirect protection to the Slovenian Armed Forces and critical infrastructure. The capabilities of combat engineering will ensure the mobility and survival of friendly forces, and prevent the manoeuvring of enemy forces. They will provide capabilities for the medium battalion battle group. General engineering capabilities will ensure the construction and maintenance of military infrastructure. Nuclear, radiological, chemical and biological defence capabilities will be able to detect and identify nuclear, radiological, chemical and biological substances, and to decontaminate personnel, equipment and assets. Modules for the medium battalion battle group will be established from a range of nuclear, radiological, chemical and biological defence capabilities. Nuclear, radiological, chemical and biological defence capabilities will be deployable. Military intelligence and reconnaissance capabilities will be used for reconnaissance, observation, targeting, data collection and analysis, and the provision of intelligence. They will consist of intelligence acquisition, analysis and distribution capabilities. These capabilities will be deployable and interoperable with the capabilities of the Alliance; they will be able to support the operation of units to the brigade level. Electronic reconnaissance and warfare capabilities will support the implementation of the Republic of Slovenia's defence interests, and protect the Slovenian Armed Forces’ units in the electromagnetic spectrum. Electronic warfare capabilities will be deployable, while electronic reconnaissance capabilities will be partially deployable. Psychological operations (PSYOPS), civil-military cooperation (CIMIC), and Military Police capabilities will be deployable and will support the operation of the Slovenian Armed Forces. 4.2.3 Combat service support capabilities Combat service support capabilities will enable the operation and sustainability of the Slovenian Armed Forces within the national context, while part of the capabilities will be able to support the Slovenian Armed Forces outside the country. Development will cover autonomous and organic deployable logistic capabilities providing logistic sustainability and support to tactical units of the Slovenian Armed Forces in international operations and missions. Tactical units of the Slovenian Armed Forces will be logistically self-sufficient. The development of non-deployable logistic capabilities to support the Slovenian Armed Forces will be directed towards increasing its combat effectiveness. The deployability of the Slovenian Armed Forces will be based on land, maritime and air strategic transport, which will be provided through various initiatives by NATO and the European Union, and by contractors. 18
