Well, first of all, the Lusitanian faction remains largely unfinished for reasons I won't go into here.

Second, Lusitanian horseman were the elite part of the Lusitanian armies. They had a good social standing and probably had a decent war-kit, even if not terribly loaded on heavy armour. So what I'm trying to say is, Lusitanian cavalry as a whole wasn't especially heavy, nor did their elites differ a lot from that - their elites would have been rather more disciplined and highly capable at hit and run attacks by charging home as well as javelin throwing, but otherwise similar in equipment. Maybe a bit more common for them to use helmets and metal armour, but otherwise, the same.

Third, the masks. Hmmm...these were put in the concept, before I came on board. We *do* know they used them, as did Iberian Celts - they appear in trophy stands in coins - but we can't exactly equate that to them being a particular attribute of the Ambakaro guard unit. Anyway, expect to appear again in EB2, but not arming an entire contingent.
