How do I get tanks?

[Archangel85]

The game cannot be made to interpret such conquerings and move a "minor" to a "major" status. You still need to research Observers, Mech Cavalry and then 19xx Armored Division tech (or so, I'm just writing this from my head - this is what I had to do as Hungary, at least).

Let me know if it works out for you!

perhaps the armor tree could be altered in a similar fashion as the air-doctrines, enableing foreign purchase, but also enableing to go the way of domestic tank production, if one chooses to do so...
