34 vehicles are copy-paste, meaning they play the same role and are identical in data to other tanks in the game. They are marked with '=✮=' or country abbreviations (ALB, SVN, etc.). The Pattons are an exception.
6 vehicles are minor modifications or export variants of tanks designated for Yugoslavia in particular and by other countries that are not in the game.
