Jaguar riders, spearman and archer. Riders from Danrell's Civ5 Maya Ancient Unit Pack, jaguar base from Civ IV (see the
Big Cats thread for the CiV conversion). Animations, sounds, and effects are CiV Hun Horse Archer and Spanish Conquistador, respectively.
The mount can easily be re-skinned with any of the Big Cats skins by a simple edit of the .gr2 file assigned to the desired .dds texture using NexusBuddy.
