A chariot archer is a mounted unit found in Civ 5. It can move four squares on open terrain, such as grassland or plains or snow, but can only go one at a time on hills, marshes, forests or snow.
It's advisable to have some melee units around when there are a lot of enemy units around, since these units have ranged combat strength of 6, but melee of only 3 so are very vunerable to melee combat.
These are rendered obsolete by a knight.
A fast Ranged Unit highly effective on flat ground, but slowed significantly when entering rough terrain.
Chariot Archers are fast ranged units, deadly on open terrain. They are slightly less powerful than the Archer but can move twice the distance. However, Chariot Archers suffer a movement penalty when entering Forest, Jungle or Hill hexes (unless roads have been constructed in them). As a mounted unit, the Chariot Archer is vulnerable to Spearmen.
Historical Info Edit
Before the invention of the stirrup, it was virtually impossible to fight from horseback. There was no way to brace oneself, and the slightest push could unhorse the warrior, with disastrous results. Horses first appeared on the battlefield pulling chariots. A chariot team usually consisted of one or two horses, a driver, and an archer. The chariots' mobility made them especially dangerous to infantry: they could rush within range, fire off a volley, then escape before the foot-bound soldiers could close with them. The greatest weakness of a chariot archer team was its inability to deal with difficult terrain. On open plains they were the kings of the ancient battlefield; in hills or woods they were at a significant disadvantage.
