18) In connection with the changes in the security environment and following the decisions of the Government, the progression of AF SR armament projects has been altered in favour of air force equipment. By approving the AF SR Air Force Development Concept (2014) the Government gave direction to air force development. 19) As a result of the changed progression of armament projects, as well as financial constraints, the former priority intent of outfitting a battalion with multirole tactical vehicles, and other equipment and materiel remains unachieved. Enhancing the combat potential of armoured vehicles already in use was begun (the modernisation of Infantry Fighting Vehicles). Despite advances in building a mobile communication system (MOKYS) for a mechanised battalion group, the desired end-state of the command, control, communication, computers and intelligence system (C4I) with an appropriate security certificate was not achieved. The AF SR are markedly lagging in capability development 20) In the context of achieved results as regards the implementation of development intentions, as well as in view of long-term development deficits, the obsolescence of major military equipment, materiel shortfalls, communication and information systems limits and in military personnel preparedness shortfalls persist. These are the reasons why the AF SR are markedly lagging behind in both capability development and in meeting NATO interoperability standards – against the 2015 standards, their levels were at about 50% of measureable indicators. 1.6 Human Resources Development in the scope of the MoD The passing of new legislation concerning the military service of professional soldiers 21) New legislation concerning the military service of professional soldiers created conditions to retain highly qualified military personnel at the operational and strategic levels in the AF SR command structure and introduced a short term form of military service to meet AF SR manning needs. Since this legislation was passed at the end of 2015, its positive contribution has not yet been felt. Preconditions for the long-term sustainability of the specialised social welfare system of professional soldiers have been created by the amendment of legislation dealing with the social welfare of policemen and soldiers. 22) In order to increase the quality of military preparation of personnel, the military character of education provided by the AF SR Academy of Milan Rastislav Štefánik was strengthened and other measures focusing on specific areas of expertise were adopted, including the possibility of attending a civilian university. 24 WHITE PAPER ON DEFENCE
