The Yugoslav People's Army (JNA) once the forth largest army in Europe. It's groung forces comprising of infantry, armour, artillery, air defence, as well as signal, engineering and chemical defence corps had 140,000 active-duty soldiers (including 90,000 conscripts) and could mobilize over a million trained reservists in wartime. The JNA had a diverse ethnic composition so when civil war broke out in Yugoslavia there were many desertions. Many felt it was not their war or their loyalities laid elsewhere. As Croatia, Bosnia and Montenegro declared their independence with only Serbia and Montenegro left in the union of Yugoslavia it was decided to abolish the JNA. Many soldiers were thorn as to whether to join the Federal Republic of Yugoslavia army (FRY) or the Army of Republika Srpska (Bosnian-Serb (VSK)) or the Republika Srpska Krajina army (Croat-Serb (VRS)). FRY although not involved in the conflicts in Croatia or Bosnia helped the Serbian states of Republika Srpska and Republika Srpska Krajina with supplies and military technology.
