In the game's words

How to use it

The Iron Flail is a Chinese heavy cavalry unit that wields the iron flail weapon. It is a strong cavalry unit with many hitpoints and a high resistance to ranged attacks. In close combat, the Iron Flail causes much melee damage and has a powerful trample attack. The Iron Flail is part of the Forbidden Army and the Imperial Army, and can be trained at the Chinese War Academy.

History

The flail is a medieval weapon used primarily in Europe during the thirteenth to fifteenth centuries. Its construction consists of a weighted head, often spiked, that is attached to a wooden handle with a whip or length of chain. While not as commonly used in Asia, the flail was quite similar to other flail weapons, such as the Chinese nunchaku, or two-section staff, and Sanjiegun, or three-section staff.

How this is worked out

Each hit: damage × every multiplier that matches the target's types × (1 − the target's resist to that damage). Two ranged units trade shots; against a melee-only unit the better of ranged and melee is used. Damage per second = hit ÷ seconds between attacks.

Armies bought with the same resources fight by Lanchester's square law: strength = (resources ÷ unit cost)² × damage per second × hit points. The edge is the square root of the strength ratio. All matchups.
