I know units can have a number of heads, torsos, shields, etc to choose from in order to look unique but I was wondering about their weapons.
The reason for this is that certain places that did not have formal (professional) armies like Sicily, Iberia, Balkans, etc are a mix of cultures so you'd have some European mixed with some Muslim.
Think El Cid (Rodrigo Diaz de Vivar) where his army was Christian and Muslim, fighting side by side. So you'd expect those units to be some european, some arab, mixed in armor and weapons. So I was wondering how far we could potentially take this..
