The Camel (Gaia) is an untrainable unit in Age of Empires II HD: The Forgotten. The Camel itself is of very limited use, since it can neither attack nor contribute to the player's economy, but it can be used for scouting, though its limited Line of Sight makes it rather ineffective. In some MegaRandom map games, the players start with a Camel as a starting scouting unit. Camels can be found in some campaign scenarios and are available in the Scenario Editor. The stats are identical to those of a Horse.
The Camel is the one-humped species also known as Dromedary (Camelus dromedarius), like the Camel Rider's mount it was edited from. All other camel units in the game are also dromedaries, except the Mameluke, who rides a two-humped Bactrian Camel (C. bactrianus).
It is unknown if the Dromedary ever existed in the Middle East as a wild species or was bred in its present form from the Bactrian Camel. Dromedary fetuses even grow two humps before the first is absorved into the second while in the womb. Nevertheless, one-humped camels escape captivity easily and have established many feral populations in North Africa, Western Asia, and even Australia.
