How could I not answer a thread by someone called 'Kryten4000'!
One of the units I am creating for Exsanguination's Alexander the Great mod will be a Thracian Peltast. It will look like the spearman, but with a 'Thracian' helmet (which looks like the civ3 Cavalry helmet, but with a bronze plume), carrying two extra javelins in his left hand behind the shield, and throwing a javelin instead of thrusting with a spear.
It may take a bit of time though. The Scythian/Persian/Saracen horse archer I'm currently working on has already taken me a month and is still not quite finished. Next will be a Macedonian pikeman, THEN the Peltast....then the Trebuchet....then the Mongol Horseman....then the Spanish Harquebusier............
(BTW, this thread should really be in the Creation & Customization forum. It makes new units easier to find if only completed animations are in the Unit Graphics section)
