Hm, if your playing as the Romans and have to fight some chariots, use your Triarii spearmen, they should be similtar to my phallanx of Armoured & Spartan Hoplites.

If your on the defense, put your men in the unit deployment screen in a square formation, put about two units on the main front, where the hammer stroke will fall hardest, with two or four support units behind them. On the right put one or two units, same with the left. On the rear put two units protecting your flank, and put your General or Captain in the center, on Guard mode along with archers or peltasts.

Put your entire force on guard mode. If you only have some Triarii, put them up front to take the blunt of the force. Hold your ground, and you should prevail. Chariots get massacred by the spears pointing forward, they just fall over dead. Occassionally a few may get through, but are always killed or rout.

**On A Side Note**

You may eat a ton of missles or peltasts and feel the urge to charge forward, but hold fast. I've done this battle defense formation many times now when horribly out numbered, and still won. You may suffer extensive losses, depending on the number of the opposition missle groups, or lack of phallanx formation units or Trarii, but you should inflict much damage to your enemy.

This is effective vs. Chariots, Horses, foot troops. Do NOT use this vs. Elephants, you'll be massacred! If you do not have any sort of strong spearmen, do not use this formation either, do the typicall battle.

I'll post a Screen Shot of my first square defense battle this weekend, if I remember. I won the battle & was out numbered by over 1,300 enemies.
