The Serbs spend about 1.5 billion a year or 2.5 percent of GDP on defence. For a state outside NATO and conflicted with neighbours and having territorial claims, this is not much. The answer to these challenges is to collect on the basis of a volunteer enlistment, a vibrant indigenous arms manufacture specialised in the production of artillery and small-caliber weapons, but besides e.g. armored vehicles, as well as to aid a controversial global friend in the form of Russia and Belarus. Today, the armed forces of more than 28,000 soldiers, supported by 3,700 gendarmes, can be maintained, and in the event of war, these forces can be easy expanded by the appointment of 50,000 conscripts.
