Camel Rider (Age of Empires II)

"Excels at killing other mounted units." - Age of Empires II Description

The Camal is a Cavalry unit that is good against cavalry,

Overview
The Camel is the first available mounted anti-Cavalry unit available in the game. Best thought of as mounted Spearmen, these units will annhiliate most hostile Cavalry that oppose them, though their weak statistics make them highly ineffective against Infantry and Archers. It is avaliable only to the Byzantines, Chinese, Mongols, Persians, Saracens, and Turks.

Tactics
The Camel is essentially a mounted spearman, having an attack bonus of +10 against horse-cavalry/elephants and +9 against other camels. Remarkably there is an exception: The Camel has no attack bonus against the Cataphract. In general, Camels have the advantage over spearmen, pikemen and halberdiers of retaining enough speed to prevent cavalry from escaping at the cost of higher food and gold costs. Using camels against civilizations that revolve around cavalry units, such as Franks, Saracens, Persians, and Mongols often lend great results. However, they cannot go head to head with other Imperial Age cavalry (although they can inflict heavy casualties before perishing), nor can they take ranged attacks well. Camels are best used only against melee cavalry or to ambush groups of cavalry archers. Do not send them against infantry, archers, cataphracts OR pears and pikes in particular.

History
"The Camel was a useful mount for warriors in desert regions of the world because it could move quickly across sand and could go long periods without water. In addition, horses shied away from the presence of camels. The Saracens made good use of camels during the Crusades; camel riders appeared out of the desert to raid Crusader outposts and caravans and then escaped back into terrain that horses could not cross."

Trivia

 * Mongols and Chinese are the only non-Middle Eastern civilizations to train Camels.
 * Camels are the only military unit that does not make the usual military sound when created, not counting Trebuchets.
