This is a unit i made by editing a default unit and using a helmet and textures that were found in Realism Invictus mod and edited by me where necessary.
Notice: When you add this unit, don't forget to change the entries in the CIV4ArtDefines_Unit.xml where it says "<Type>ART_DEF_UNIT_CROSSBOWMAN_GRECO_ROMAN</Type>"
EDIT: The original texture and helmet are from Bakuel's unit "Byzantine Longbowman" which can be found in his "Byzantine Middle Age Unit Pack".
