I'm creating my own mods in Civ4 but I have a problem with unique unit. I've done some unit for example I have an Infantry for general team and I have a Wehrmacht Infantry, and a Soviet Infantry that I want to be unique. They say that it replace the Infantry but when I do the tech even if I'm not German or Russian I can do the 3 unit ... what I must do to just have one of these three unit... and for your information I've put their unitclass and unit type in the civilization info...
