Beware of Mac's light lancers
Beware of Macedonian light lancers. They are fast like hell and allways appear in big number. If you can seperate one of them and encircle with three to five horse archers you can kill them rapidly. Just be careful when they flee, they will run through your lines and you will get friendly fire. When they attack in closed formation 5, 6, 7 or more units they are really dangerous, even to general units. They attack from several sides and can delet heavy cav in minutes.
Best tactics against them is to protect your HA with lots of barb cav. Foot archers are very effective ti fight them, too, but you have to protect them very good. This is a high mobile battle so always be allert.
Their hoplite units are no problem. They are so slow that you can kill them without losses. They look like hedgehogs with arrows in their backs! ~D
Your only in trouble if you run out of arrows.
