This is a simple guide to what units are most effective at countering other units. Sometimes this is because the unit gets bonus damage (for example the Axeman does quadruple damage against enemy infantry) and sometimes it is simply because the unit's stats are suited to beating the opposing unit. (Toxotes may be weak, but their range lets them beat slow infantry units.)
