I’ve only seen russa build a fleet when the game was over for all purposes. Germany had fallen and Japan was about to. So he put 2 BB in the pac using a IC that Japan built. I was foolish and went after US with Japan. Suicide.
if you have excess money to buy navy with russia i’d rather spend it on fighters and then use the one sub as sort of a fodder pieace. that way once your navy objective has been covered you can switch to land easily and i think fighters are great.
Actually, if you needed fodder pieces for Russia, I’d go with Transports. Then you can shoot down planes. :P
