In previous civ games, units have only a few levels: conscript, regular, veteran, and elite. Now in Civ4, there are more than 40 promotions you can give to your units as they gain experience, enabling you to customize your units to make them more unique and more powerful. Some of the promotions give your units a strength bonus, some give your units a bonus against a certain unit type, some make your units better on certain terrain types, while some give your units special abilities such as using enemy roads, faster healing, amphibious attack, and city raider.

In addition, some promotions (like Morale and Leadership) require the use of a Great General, a unit available in Warlords and Beyond the Sword. By joining a Great General to a unit, these promotions become available.

However, not all promotions are available to all units, and the better promotions have other, lesser promotions as prerequisites. The escalating cost of the next promotion ensures that few units will have more than 3-5 promotions, so choose carefully.

NOTE: Information in this section is correct as of Beyond the Sword v3.17.
