Was switching to horses ever a realistic option for Tuaregs? Keeping them in the central Sahara can't be easy, and while Tuareg forces often intervened both in the Sudan and the Maghreb, I don't recall there ever being any based there on a more-or-less permanent basis. Switching riding animal in the middle of a campaign is unlikely to be a good idea even if the new one is better, because the men will be unused to it.David Kuijt wrote: One critical aspect of the historical record was this -- in all cases except Tuaregs, armies that had a chance to switch from Camels to Horses as they got more wealthy and more successful, all did so.
One use of camels that David didn't mention is Cyrus' supposed stratagem of mounting his cavalry on baggage camels to discomfit Lydian cavalry. Presumably another battle card if it's to be represented.
At the very tail end of the period, there's also the use of camels to carry very light artillery. Mounted Artillery? Or ignore as completely marginal.
