Yuri's revenge: a detailed introduction to the last stage of the Soviet Union?

Attack: build a nuclear bomb and an iron curtain after coming out. Bomb the allied spirit lighthouse with nuclear bombs, rebuild the time plane and weather control machine, and prepare nine apocalypse tanks at the same time. After everything is ok, throw the apocalypse into the open space near the fortress through the transformation of time and space, immediately surround the iron curtain when you arrive, and then point to the fortress. I believe it's not a problem to take care of the fort in 20 seconds. If you don't feel safe, there is another trick: replace one of the revelations with a multi-purpose vehicle with a seal during transmission. Behind the Iron Curtain, the apocalypse directly destroyed the crocodile guns around, and the multi-function vehicle took the opportunity to let the seals out, and the seals directly blew up the fortress to pass the customs.

Defense: build a large number of armed helicopters, deploy them in places where the terrain can hold the intersection, and build a bunch of American soldiers to block the intersection. Generally speaking, the enemy can't even think about it.

Tip: There is a secret science and technology laboratory in the lower right corner of the map. Cannons can be used after the occupation. In the case of sufficient electricity, the power plant is used to propel, and a prism tower and a giant gun are placed during the propulsion. I think Yuri's base will be completed soon. Similarly, you can also put the giant gun in the base where you can hit the intersection. I dare them not to come over.
