Replacements

Every civilization in Civilization IV has its own unique unit. A unique unit, or UU for short, is a unit that can only be built by that civilization. It always replaces some other unit, not allowing that one to be built at all.

The only unique unit that is not a replacement for a military one is the Fast Worker, which replaces the Worker.
