In Conflict of Nations, there are three different doctrines: European, Western, and Eastern. Each doctrine has its own unique strengths and weaknesses, which affects the research timelines for various units.

Why Doctrines Matter:

1. European Doctrine: Allows earlier research of mechanized infantry but delays the availability of Armored Fighting Vehicles.
2. Western Doctrine: Might allow faster research of air units but delay ground units.
3. Eastern Doctrine: Could enable quicker access to artillery units while slowing down the development of other types.

Example:

• If your opponent is using the European Doctrine, they can research mechanized infantry earlier than you if you are using the Western or Eastern Doctrine. However, they will find it takes longer to research and deploy Armored Fighting Vehicles compared to the other doctrines.

Strategic Differences: Understanding these differences is key to planning your strategy and anticipating your opponent's capabilities. Each doctrine offers unique advantages and trade-offs, requiring players to adapt their tactics accordingly.
