Is Cataphract Historically Accurate?? | Age of Empire 2

The Byzantine Cataphract. A fan favorite unit that players adored since the release of age of kings. One of the coolest looking units in the game with a special bonus attack against infantry good resistance against camel units and big amount of hit points with mobility and fast attack speed. The Cataphract has been reskinned few times during the years but not a lot has changed. Today we are going to see how historically correct is the Cataphract unit. In the Byzantine Empire or Roman Empire or Empire of the Greeks as Westerners used to call it gradually abandoned its legions which consisted of the Legionaries and by the 7th century focused more on heavy cavalry. This is where the cataphracts made their appearance in the Roman ranks.
Cataphracts are anti-infantry cavalry units with low pierce armor and attack, but resist anti-cavalry attacks. All these qualities make them very distinct from the Knight line. As such, despite both being heavy cavalry, they play different and often complementary roles. Cataphracts in the Castle Age are mostly seen only against Native American civilizations, Goths, and Hindustanis, which rely on archer-resistant infantry. Byzantines do not have any bonuses to get a Castle up earlier than most civilizations, and the high cost also limits their usage in the Castle Age. Cataphracts really need their Imperial Age upgrades to shine.
