You are right to zoom in. But the basic culture abd repeat pattern of Russia and chinese empire is astonishing as well. It might not be used to explain Air Force but the general picture is still there. For this round, expanding an empire just be force is odd, except for Mongolian empire. Usually you start with soft bit. Seems this round is very Mongolian.
