         It can be complicated at first, you might think you need to go fascist in order to get storm troopers, and fascism isnt available in the demo, its simple, look for another country with a training camp, if your strong enough, declare war on the country for the training camps or trade for the land. hope it helps! let me know if i made any mistakes!

    2. How to get tanks in warnament demo:

        3 ways to do this, the first way is to wait. sometimes, if your lucky enough, a tank will randomly spawn in your capital, 2nd way is to trade for a tank, if you see a country with a tank, trade with them, click on the province that has the tanks, select how much tanks you want, and done! 3rd way to to look for a country with machine factory II. machine factory II isnt available in the demo, so, just invade a country with it or trade for the province.

   3. I cant do anything with uranium in the demo, how do i use it?
