Special unit
Special units are a special type of mobile army with unique abilities. Each special unit is represented by an icon and is shown next to the amount of actual armies on a territory.
Attack and Defence power
The Attack Power is the number of armies the unit is worth when attacking. The Defence Power is the number of armies the unit is worth when defending. Usually the values of both are the same as each other.
Combat order
The Combat order determines which special units take damage before others. The lower the number, the sooner the special unit takes damage. Negative numbers mean the special unit will take damage before normal armies. A commander has a combat order of 10000.
Damage to kill
When a unit has Damage to kill, it means all armies the unit is worth while defending must be killed in one go. The unit will not be partially damaged.
Health
When a unit has Health, it means all these armies must be killed to destroy the unit. The unit does not need to be killed in one go.
Visible to all players
If a unit is Visible to all players then players can see the territory the unit is on, regardless of normal fog rules.
