Thanks Sun. I have tried to add those units but they crash my game and I hate that. In all actuality, most Byzantine units were barbarian mercs. Alot of people don't know that Justinian's recnquest of parts of the old Roman empire was done for the most partby Hunnic cavalry. Armenia was always fought over due to its hardy infantry and lust for war. But disclipline was always lacking. That was one of the major differences between the Romans and Byzantines. One depended on Drill and discipline. The other depended on generalship and strategy. So far, I have just either changed names of units and/or build restrictions so that the Byzantines have to hold onto certain provinces if it wants to add the more "exotic" units to the army.
