Slovenia
During the Ten-Day War, the Yugoslav People's Army (YPA) attempted to regain control over border crossings, airports and other strategic positions in Slovenia. The Slovenian Territorial Defence had no armoured units of its own, as such YPA M-84s were commonly used to break through barricades. The YPA lost some 20 M-84s to insurgent tactics. Slovenia inherited all the M-84s within its territory, once the ceasefire and Slovenia's independence was accepted.
