In answer to In's question about "Anti aircraft missiles stationed back in times of ex-Yugoslavia."
Larger Yugoslav army units had considerable tactical air defense assets, designed to defend major troop concentrations against enemy air strikes. The ground forces had four surface-to-air missile regiments and eleven antiaircraft artillery regiments. The former operated large numbers of Soviet SA-6, SA-7, SA-9, SA-13, SA-14, SA-16 missiles.
Yugoslav antiaircraft artillery regiments operated over 5,000 guns. Self-propelled gun systems included the Soviet-made 57-mm dual ZSU-57-2 gun systems and the domestically produced triple 20mm BOV-3 and dual 30mm BOV-30.
