Unit Index

Units are an all-important part of a Civilization game. In Civ IV, instead of having separate attack and defense ratings, the units now have only one strength rating. Instead of having only a few experience levels (ex. Conscript, Regular, Veteran, Elite), now there is a new RPG-style promotions system that allows you to customize your units to make them more unique and more powerful as they gain experience. There are more than 40 promotions in Civ IV. Another important change is that alot of units now have bonuses when attacking other unit types, encouraging players to have a diversified military. For example, Axemen have a 50% attack bonus when attacking melee units, and spearmen receive a 100% bonus when attacking mounted units. These changes make combat much more interesting.

There are 83 units in Civilization IV, including Animals & all 7 Missionaries. They are listed in alphabetical order in the table below.

Legend:
Str. = Strength
Move = Movement or Range
Cost = Hammer Cost (for Normal game speed)
