Each country has its own unique geography. Battle tactics always depend on landscape and size of a country or combat operational area. All these specifics should be considered during battle tactics. Each phase of war is different and unique for all countries in the game. Battlefields have different landscape.
Here is a list of some bonuses and penalties for military units in different landscapes:
Submarines have penalty in shallow waters
Mechanized units have penalty in desert, city and mountain areas
Infantry has bonus in city and mountain areas
All Air units have penalties in mountains and bonus in desert
Infantry has bonus in jungle, mountains and city
You may want to consider landscapes If you move your units to a proxy war or build military base abroad and locate your army there.
On the screenshot below you can see phase of war with many combat areas. Each area has its own penalty and bonuses. The wiped off area is for text. We still work on texts and letter styles and can’t demonstrate it at the moment.
