The JNA consisted of the ground forces, air force and navy. It was organized into four military regions which were further divided into districts that were responsible for administrative tasks such as draft registration, mobilization, and construction and maintenance of military facilities. The regions were: Belgrade (responsible for eastern Croatia, Serbia and Bosnia and Herzegovina), Zagreb (Slovenia and northern Croatia), Skopje (Republic of Macedonia, Southern Serbia and Montenegro) and Split Naval Region. Of the JNA's 680,000 soldiers, more than 180,000 were conscripts.

In 1990, the army had nearly completed a major overhaul of its basic force structure. It eliminated its old divisional infantry organization and established the brigade as the largest operational unit. The army converted ten of twelve infantry divisions into twenty-nine tank, mechanized and mountain infantry brigades with integral artillery, air defense and anti-tank regiments. One airborne brigade was organized before 1990. The shift to brigade-level organization provided greater operational flexibility, maneuverability, tactical initiative and reduced the possibility that large army units would be destroyed in set piece engagements with an aggressor. The change created many senior field command positions that would develop relatively young and talented officers. The brigade structure had advantages at a time of declining manpower.
