What are a units attack, defense, and movement values used for?
All land and ship units have the following values (air units are a bit different, so see the earlier aircraft question) for attack, defense, and movement. Movement is the easiest: this is the number of tiles the unit can move in a turn. Most early units can only move 1 tile. However, also be aware of the fact that some tiles ‘require’ multiple movement points. For example, if a unit has 2 movement, it can’t go over 2 hill tiles in a turn, because a hill tile uses up 2 movement per tile instead of the normal 1 – the unit can only go over 1 hill. Also, when on a road, a unit can travel three tiles, regardless of the underlying terrain. The attack and defense values are used for combat. Although it may appear that if an attacking unit’s attack strength is 2, and the defender has a defense of 2, the probability of either unit winning is 50%, this is not so. This is because there are a series of value modifiers that can affect both the attacker and defender. There are things to calculate in
