Here is the situation,
I am trying to give Turkey some tank designs (M48 and M60 etc.) in Mid.East scenario but I couldn't do it with map editor.I can add general technologies to the list but I couldn't see the part which we add/remove unit designs.
I tried something else.During the game I bought reactive armor tech. from Israel.However, there was no new tank designs in the research list. So I needed to buy unit designs as well!
I am very confused here

How can I give a country unit designs with using map editor?
