Apologies in advance if this has already been covered, however when I utilized the search function I couldn't find anything on this topic. I am in the editor and when I go to select certain units to place, such as any type of helicopter or a number of tanks they are grayed out. Any idea why this is? I can still place them on the map, however when I hit test it seems to not be able to load them as playable or anything of the such.
