Combat or battle is a regrettable but necessary part of most strategy games. The attacker's attack strength and the defender's defensive strength are major factors in the outcome. In most games, the raw strengths can be increased by "veteran" status or similar experience-based enhancements, and defenders may in addition have a terrain bonus, making them stronger in forest or hilly ground, for example.

Combat outcomes are simple. Each unit's chance of losing is proportional to the relevant strength.

Combat is more complex than in Sid Meier's Civilization. Participants engage in several bouts, with the loser of each bout losing a small proportion of its health. The eventual winner usually has reduced health, which takes time to recover.

Battle outcomes are not random but depend precisely on the relative strengths (with a couple of other factors occasionally entering the equation). Before attacking, you can call up a diagram that shows the strengths and the outcome.
