Try with Carthage.

Use Militia and Iberian Infantry and only 1 unit of Round Shield Cavalry and 1 General, 2 Peltasts, no Hoplites against 6 units of Equites, 1 unit of Velites, 1 Roman Archer, 1 Wardogs, 1 General and 4 Hastati.

You will surely see how difficult it is.

I guarantee total defeat.
