Perhaps the most widely misunderstood aspect of AOM is the unit counter system. For example, standard thought dictates that infantry counters cavalry, yet in a 1v1 fight a hippikon always trumps a hoplite. With this in mind, how can we possibly say that one unit is superior to another? The answer to this question depends on a lot of factors, especially in a game like AOM. Consider the case of 1v1 combat; whoever survives longer obviously wins. There must be rules governing this process, and the purpose of this article is to find them. A little bit of math will be involved. You can read the conclusions first if you are not interested in the details.
