What factors affect Combat Strength bonuses?

[Trigan Emperor]

What factors in the game have an effect on Combat Strength in unit vs unit combat?

Is there anything missing from this list?

- Unit Combat Strength

- Unit Class modifiers (such as Anti-Cavalry vs Cavalry, Melee vs Anti-Cavalry)

- Unit Promotions

- Terrain modifiers (including Amphibious/River penalties)

- Fortification modifier (for not moving unit in previous turns)

- Support/Flanking bonuses

- Damaged unit penalty

- Insufficient strategic resource penalty*

- Embarked penalty ('Adjusted base strength when embarked')*

- Leader Abilities, including those of Frederick Barbarossa, Genghis Khan, Hojo Tokimune, Matthias Corvinus, Montezuma, Phillip II, Shaka, Teddy Roosevelt, Tomyris*

- Great General/Admiral

- Governor Victor (and Ibrahim for the Ottomans)

- Policy cards, such as Discipline, Bastions, Wars of Religion, National Identity, Their Finest Hour

- Governments, such as Oligarchy, Communism and Fascism

- Diplomatic Visibility ('Intel on enemy movements')

- Beliefs, such as Defender of the Faith and Crusade

- Military Alliance (+5 Combat Strength against units of players at war with you and your ally)

- Corps (+10) and Armies (+17)

- World Congress resolution (to certain types of military unit)

- Game difficulty

There's also an "insufficient strategic resource" combat strength penalty (strategic resource income < strategic resource maintenance), and if stockpiles are at zero. I think it is -20 for units that depend on that strategic resource (e.g. ironclads and coal)?

Thanks!

That's a good one. Allows for some interesting strategic war planning.

ETA: Added it to the list.

Adjusted strength whilst being at sea.
Leader ability (eg Frederick and Teddy R)
Amphibious / attacking across a river penalty which is similar to terrain modifier

Thanks.

I had a look through the Leaders. Others boosting Combat Strength are Genghis Khan, Hojo Tokimune, Matthias Corvinus, Montezuma, Phillip II, Shaka and Tomyris.

I'll add the new Combat Strength factors to the list.
