I'm not a pro at this game so my understanding might be wrong. But for me, this game is a bit like a simple comparison of the number of military buildings and the length of online time between players. Wars between two countries are just direct collisions of two continuous supply lines.
If paratroopers and other long-range facilities are added, such as artillery with explosive ranges, real bombers that can fly across roads, etc., the wars will become complex and tactical.
